Description

DESCRIPTION

Procedure for regulating the processing of a tape of material by means of registration marks and a device for carrying out the procedure

The invention relates to a method for regulating the processing of a tape of material, especially a tape of packaging material, having registration marks guided so that they pass in front of a processing equipment for the purposes of processing. Furthermore, the invention relates to a device for processing a strip of material, especially a strip of packaging material, in a processing equipment with at least one drive cylinder to drive the strip of material, with at least one tool unit for carrying out the aforementioned procedure with at least one sensor to detect registration marks of the material guided tape so that it passes in front of the sensor, with an evaluation equipment to determine a deviation from an actual position of at least one processing equipment processing tool, position corresponding to the detection event of a registration mark by the at least one sensor, relative to a predetermined position of the at least one processing tool for the same detection event, and with a regulation equipment for the regulation of the actual processing position of the at least one tool of p friction by the deviation, determined by the evaluation team, between the actual position and the predetermined position of the at least one processing tool.

The tapes of material are processed multiple times in several consecutive steps, each isolated processing step being repeated with predetermined distances along the tape of material. In this way they can be manufactured with a large number of sections of the same type arranged one behind the other. During processing, the material belt is typically driven by at least one drive cylinder.

The ribbons of material can be provided, for example, with a multi-color print. In order to ensure high print quality in this regard, the isolated printing steps must be carried out in synchronization, that is to say in such a way that they coincide with each other. Alternatively or additionally, by material tape and projected use of the material tape other processing steps such as stamping, cutting, folding, die-cutting and punching can be mutually adapted to each other, so that material tapes or cuts of material produced as accurately as possible.

Those core principles are, for the most part, independent of the tape material. The tapes of material to be processed can be, for example, single-layer materials. However, material tapes which are composed of a composite material and / or a laminate may also be considered. These can be used, for example, as packaging material. As for the packaging material, it may be, for example, a laminate for packaging material with individual layers, attached one below the other, of different materials that provide different properties to the laminate for packaging material. For food, in many cases so-called laminates for cardboard / plastic packaging material or composite cardboard packaging are taken into account, which are formed by a laminate comprising a cardboard layer and outer layers of plastic, especially thermoplastic, for example, made of polyethylene (PE). The cardboard provides sufficient stability to the packages so that the packages can be easily handled and, for example, stacked. The plastic layers can be stacked and protect the cardboard from food moisture from the absorption of unwanted materials from the package. Additionally, more layers may be provided as barrier layers, which are so composed, for example, of aluminum, polyamide and / or an ethylene vinyl alcohol, that they prevent a diffusion of oxygen and other gases through the package. The corresponding tapes of material are comparatively thick and comparatively consistent, which can make it difficult to accurately process the tapes of material in steps to be performed consecutively.

For the regulation of the processing of a tape of material having registration marks guided so that they pass in front of a processing equipment for the purposes of processing, a so-called regulation of registration or regulation of printing marks is typically used. For this, the material tape is provided, at certain distances, with registration marks or print marks that can be detected by an optical sensor as soon as they pass through the sensor. The imprint marks represent, in this regard, registration marks affixed by imprint which may, in principle, also be provided in a different way from the imprint. Such registration marks are disclosed in WO 2012/039934 A2 for a regulation of a processing equipment to stamp a moving tape. The disclosure from WO 2012/039934 A2 is indicated as the closest state of the art with respect to the object of independent claims 1 and 10.

In most cases, registration mark detection is performed at a position that corresponds to a large number of integer repeat lengths of the media tape. The repeat length is determined by the length of sections of the same type of material tape, for example, cuts taken out of the material, especially cuts of packaging material. In this case, a repeat length would be defined, for example, by the distances of the leading edges of the subsequent packaging material cuts. However, alternatively or additionally, the repeat length can also be understood as the distance of two processing points of the same type along the strip of material. For example, if the same decoration is always reprinted, the repeat length would be the distance between two identical points of consecutive decorations. The registration marks are preferably also provided at distances corresponding to the repetition length.

If a registration mark is detected by the sensor, the position at which the next processing tool was found at the time of registration mark detection is also detected, i.e. in the detection event. This position is then compared to the default position of the processing tool where the processing tool was to be at the time of registration mark detection. From this comparison a deviation between the two positions is deduced, which optimally, as necessary, equals zero but can also be positive or negative. To compensate for this deviation, the regulation equipment regulates the position of the processing tool using the absolute value and the forecast of the deviation. For this purpose the processing tool is accelerated for a short period of time or slowed down for a short period of time. This implies that the actuation of the processing tool moves it somewhat more quickly or somewhat more slowly for a short period of time. The time interval in which acceleration and / or slowdown or delay is performed is typically shorter than the time interval between the detection of two consecutive registration marks by the at least one sensor. Acceleration or slowdown for a short period of time seeks to alter the position of the processing tool so that it coincides with the default position of the processing tool. Therefore, and due to the deviations, insignificant in most cases, the acceleration or slowdown also takes place only for a short period of time. Due to the speed, in most cases, of the material belts, the slowdown or the delay or the acceleration is implemented as an impulse.

In practice it has been shown that a very high regulating effort must be made to achieve precise processing of the material tapes. This applies all the more as inaccuracies from previous job steps must be taken into account in subsequent processing steps. For example, a registration mark can be incorporated into one processing for further processing with another processing tool. For example, on processing equipment a part of the material tape may be punched out or a fold line is provided on the material tape. In order to now orient the post-processing precisely in the pre-processing and thus take account of any errors in the pre-processing, the edge of the material tape can be used around the punched part of the material tape or the line The crease can be used as a registration mark for a subsequent processing step, for example, to guide post-processing at the stamp or crease site.

In addition, slippage and / or acceleration or retardation of the feed rate of the media tape may occur during transport of the media tape, causing registration marks to be undetected by the sensor in the precise time order as planned. Thus, on the one hand, deviations from the regular registration mark detection conditions and deviations of the position of the processing tools from the predetermined position of the processing tools can occur independently of each other. The regulation must seek joint compensation for both deviations.

This is especially problematic for those applications where very high belt speeds and / or strong accelerations of the material belt must be achieved. With an increasing interest in increasingly efficient manufacturing and decreasing average cost, there is a constant effort to continue to increase belt speeds and accelerations of the material belt during processing of the material belt. However, this always results in operating states in which the regulation is not available with sufficient speed or with sufficient precision to compensate for or avoid errors in relation to the material belt and / or the tool. processing. If, in this regard, predetermined fault tolerances are exceeded, there are parts of the material tape that must be removed as waste. Thus there is an objective of optimization so that high belt speeds and strong accelerations are made possible while reducing waste in order to produce in the most economical way possible. So far, especially in the case of packaging material tapes, this optimization objective has not been satisfactorily achieved.

Accordingly, the present invention is based on the aim of configuring and perfecting the method and the device of the aforementioned type respectively so that high speeds of tape and accelerations of the material tape can be realized when starting the device to process the tape material with little debris at the same time.

The object is achieved, according to claim 1, by a method for regulating the processing of a tape of material, especially a tape of packaging material, which has registration marks guided so that they pass in front of an equipment of processing for the purposes of processing,

- wherein the registration marks are guided such that they pass in front of at least one sensor that detects registration marks,

- in which an evaluation equipment determines the deviation of an actual position of at least one processing tool of the processing equipment, a position that corresponds to the detection event of a registration mark by means of the at least one sensor, with respect to a predetermined position of the at least one processing tool for the same detection event,

- wherein a regulating equipment regulates the actual processing position of the at least one processing tool by means of the deviation, determined by the evaluation equipment, between the actual position and the predetermined position of the at least one processing tool ,

- in which the evaluation equipment determines, by consecutive registration mark detection events by means of the at least one sensor, the actual distance of consecutive registration marks with respect to the length system of the at least one actuating cylinder, especially with respect to the angular difference and / or the perimeter difference of the drive cylinder, and is positioned relative to an expected distance of the registration marks from the length system of the at least one drive cylinder,

- in which, by the relationship between the actual distance and the expected distance of the registration marks, a predetermined control value is determined and

- wherein a control equipment, preferably a preset control equipment, adapts the speed of the at least one processing tool depending on the predetermined control value determined.

The aforementioned objective is further achieved with a device according to the preamble of claim 10 because the evaluation equipment is configured to determine a predetermined control value, which depends on the belt speed of the material belt in the zone of the at least one sensor, by consecutive detection events of registration marks by means of the at least one sensor, determining the predetermined control value, which is based on the relationship between the actual distance of consecutive registration marks with respect to the length system of the at least one drive cylinder, especially with respect to the angular difference and / or the perimeter difference of the drive cylinder, and a distance, to be expected, of the registration marks with respect to the length system of the at least one cylinder drive, and because control equipment, preferably a preset control equipment, is provided for adapting the speed of the at least one processing tool depending on the predetermined control value determined.

According to the invention, the regulation of the position of the processing tool of the processing equipment is complemented by a control of the speed of the processing tool. In this regard, the speed of the processing tool is not calculated by the speed of the material belt drive as such, for example by the angular speed or the perimeter speed of a cylinder or roller for the belt drive of material or by the number of revolutions of a motor to drive the belt of material. Rather, the speed of the media tape or a speed parameter corresponding to the speed of the media tape is detected by detecting consecutive registration marks and thus very precisely. High precision is achieved in that the effective speed or a predetermined control value corresponding to the effective speed of the material belt, for example in the form of a speed parameter, of the material belt is determined in the manner described.

When registration marks are not provided at precisely predetermined distances on the media tape, for example, because prior processing of the media tape, where, for example, registration marks have been formed, has been performed with defects, the actual material tape speed or the predetermined tape speed is reached less than the relevant speed for ongoing processing, ie effective tape speed, of the material tape. This describes, for example, the speed with which the registration marks are driven to the next processing equipment or processing tool. When processing the media tape with the Rendering Tool is to be tailored to the registration marks, the speed of the registration marks, which may but need not coincide with the absolute speed of the material tape or with the default tape speed is critical.

The detection of the belt speed by the registration marks is also, therefore, more accurate than the determination of the belt speed by the drive for the material belt, either with respect to a motor, at the speed of a cylinder drive or other parameter, since this detects a displacement between the drive and the material belt and / or an expansion of the material belt during transport. This can be taken into account in the post processing of the material tape.

Finally, detecting the effective speed of the web of material allows the speed of the processing tool to be adapted to the effective speed of the web. In this regard, however, the speed of the processing tool is not regulated, but is controlled. The control is characterized by an open development of the action, in which an input quantity, in accordance with certain legal norms or specifications, influences an output quantity without the influence result being continuously monitored or corrected . On the other hand, during regulation, an output quantity, which is also called the regulation quantity or actual value, is continuously detected and compared with a guide quantity or a nominal value. Therefore, regulation is characterized by a closed development of the action, the so-called regulation cycle, which serves to adapt the output quantity to the guide quantity or nominal quantity.

In other words, the speed of the processing tool increases when an increasing effective tape speed is determined, while the speed of the processing tool decreases when a decreasing effective tape speed is determined. Since the speed of the processing tools for the processing of material tapes can typically be adjusted very precisely and reproducibly, in the present case the continuous detection of the speed of the processing tool and the regulation by means of a comparison with the predetermined speed of the processing tool. In addition, the control takes into account that the desired speed of the processing tool should not be kept more or less constant, but should vary very quickly as necessary, which may be the case especially when starting and running the installation for material tape processing. With this, a regulation could be slightly overloaded and result in imprecise or unstable operation of the installation.

As for the material tape, it is especially a packaging material tape, since the process can be used particularly advantageously in these material tapes. This applies especially in the case of packaging materials in the form of packaging material laminates, which, in the case of a cardboard / plastic packaging material laminate, can have at least one inner layer of caron and outer layers of plastic that can be sealed, especially printed. In most cases at least one more layer is added, especially aluminum. The laminates of packaging material are used to form packages, which, in most cases, serve to fill them with food.

The material belt can be easily, reliably and very precisely driven by means of at least one drive cylinder. In this connection, there can be a friction drive between the drive cylinder and the material belt, so that the material belt is driven at least essentially, for example, with the perimeter speed of the drive cylinder. The perimeter speed of the drive cylinder and the belt speed can thus correspond to each other. In the case of actuation by means of an actuation cylinder, the preset control value, determined by the detection of the registration marks by the at least one sensor, for example in the form of a speed parameter, can refer to the lengths of the at least one drive cylinder. Consecutive registration mark detection events are thus related, for example, to the path over which the drive cylinder has rotated again between the detection of consecutive registration marks. The corresponding preset control value or speed parameter may in this respect refer, for simplicity, to the angular difference and / or the perimeter difference of the cylinder or drive cylinder operating between two detection events. The angular difference is the angle around which the cylinder has continued to rotate between the corresponding detection events and the perimeter difference is the path around which a perimeter point has continued to move between the corresponding detection events along the perimeter. Thus, the perimeter difference and the angular difference are directly related to each other in the case of cylinders with a round cross section.

Otherwise, the evaluation equipment can determine, by detection events, the actual distance of consecutive registration marks with respect to the length system of the at least one drive cylinder, especially with respect to the angular difference and / or the difference in perimeter of the corresponding cylinder, and relate it to the expected distance of the registration marks from the system of lengths of the at least one corresponding cylinder. The absolute value and the forecast of the deviations determined in this regard can be used very easily in this respect to adapt the speed of the processing tool. In this regard, for simplicity, the speed of the processing tool can first be adjusted to be identical to the speed of the drive cylinder. When a deviation of both speeds is to be taken into account, it is detected as described by a measurement technique and, by means of the preset control value, is taken into account in order to compensate for the deviation. The described deviation can be used accordingly. to precisely modify the speed of the processing tool.

In other words, by the relationship between the actual determined distance of the registration marks from the drive cylinder length system and the expected distance of the registration marks, a preset control value can be determined which can then be given in the regulation circuit. The preset control value changes the speed of the processing tool primarily in the direction of a control, while otherwise the position of the processing tool is especially regulated by different speeds printed over a short period of time. In this regard, the amount of adjustment can be deduced especially from an interference of the preset speed control and position regulation, respectively, of the at least one processing tool.

The relationship with drive cylinder length systems can be achieved, for example, because for each detection event of a registration mark the distance at which a given reference point along the perimeter of the drive cylinder is determined is determined. away from a certain reference location on the perimeter of the drive cylinder. This distance can be 300mm (L1) for one detection event and 405mm (L2) for the next detection event. If the distance to be expected in theory between two consecutive registration marks is 100 mm (LT), as a distance from the reference point to the reference point in the next detection event, a value of 400 mm would be expected. The corresponding difference between the actual and expected value from the length system is thus 5 mm (LD) and can be used to determine the default control value.

LD = L2 - L1 LT

For this purpose, first of all, a normalization is offered regarding the length value that must be Wait, which can be used as a preset control value or to determine a preset control value, for example in the form of a speed parameter (DV), for which the drive cylinder perimeter speed (VA) must be used .

VD = VA ■ (LT - LD) / LT

Instead of perimeter distances or perimeter lengths, the calculation, described above by way of example, of a predetermined control value could be implemented, also by angular differences of a reference point of the drive cylinder with respect to an angular reference of the drive cylinder.

Next, for a better understanding and in order to avoid unnecessary repetitions, the procedure and the device of the type mentioned above are described without differentiating in detail respectively between the procedure and the device. For the person skilled in the art, however, it is clear from the context which characteristics are respectively preferred for the device and the method.

In a first preferred configuration of the method, the evaluation equipment determines as a predetermined control value a speed parameter, which depends on the belt speed of the material belt in the area of the at least one sensor, with respect to the system of lengths of the at least one drive cylinder. This simplifies control as the speed to be adjusted can be corrected or adapted. Thus, if necessary, a speed target, depending on the speed parameter, is also derived for the processing tool, which can be adjusted or predetermined accordingly.

Alternatively or additionally it is preferred that the at least one processing tool is motor driven. This allows the speed of movement of the processing tool to be adjusted very precisely and reliably. In this regard it is more preferred that the processing tool rotates around an axis. This is a simple movement, which can be easily maintained at a more or less constant speed. In addition, regulation of the position of the processing tool is quite possible. This is especially true if the axis is oriented parallel to the material belt and perpendicular to the transport direction of the material belt, respectively in the area of the processing equipment or the processing tool. Thus, the rotation speed of the processing tool can be easily adapted to the belt speed. In this regard, the rotation can be carried out both in the direction of movement of the material belt and in the opposite direction to this direction. In order to easily provide rotary processing tools, they may be formed or supported by a drive cylinder.

Regardless of the actuation and type of movement of the processing tool, the processing position of the at least one processing tool can be regulated at least also by means of an acceleration and / or a delay, especially by way of impulse, for a short period of time, of the speed of the processing tool. Thus the position of the at least one processing tool can easily be adapted to the sections of the material tape to be processed. This especially applies to rotary processing tools and more especially to those with an axis of rotation that is oriented parallel to the belt of material and perpendicular to the belt speed, respectively in the area of the processing equipment or of the processing tool.

As an alternative or additionally, for stable and fast regulation, it is convenient that the processing position of the at least one processing tool is regulated by means of a regulation circuit by acceleration or slowdown or delay for a short period of time. at least one processing tool that moves at a predetermined speed. Regardless, if necessary, as a complement, the default speed of the at least one processing tool can be increased or decreased by means of a preset control. This preset control can be implemented easily and with sufficient precision.

Particularly conveniently, the method can be used when in the case of the at least one processing tool it is a cutting tool, a drilling tool, a die tool, an embossing tool, a folding tool and / or or a printing tool. These processing tools must generally work very precisely and are also available in case of very fast regulation regulation.

Furthermore, the method is especially effective with the use of material tapes in the form of packaging material tapes, preferably a packaging material laminate, especially a cardboard / plastic packaging material laminate. Specifically, with the known method, they do not satisfactorily process corresponding material tapes.

As an alternative or additionally, the present procedure may refer to registration marks that are integrated into a decoration or are provided next to a decoration. If necessary, however, print marks, die cuts, folds, embossing and / or material differences are also taken into account. In this way, the following processing of the material tape can be adapted to previous processing of the material tape. In the case of die cuts and folds, for example, cavities or elevations of the material tape can be formed which can be detected by a sensor. If parts of the material tape are punched, edges are formed that can also be detected by a sensor. If necessary, parts of the material tape are punched to make straws easier on them, place pouches or open packages.

So that other marks are not detected by mistake such as the registration marks that must be detected by the at least one sensor, a so-called door control can be used. In this regard, a release device is used, which opens windows as a function of time and / or as a function of length, for example, depending on the system of lengths of the material tape, windows in which the detection of registration marks. Only then can a registration mark be detected by the at least one sensor or only then can the detection result be transmitted to or processed by an evaluation team. Thus, the windows are always open for a certain period of time or for a certain length of the material tape in which the next registration mark is expected. Since the distance of the registration marks is known at least approximately, by detecting the last registration mark and additionally, if necessary, the speed of the material tape, it can be evaluated when approximately the following should be detected registration mark. Then, around the next expected registration mark, another window is opened by the releasing team, especially with a predetermined width.

In order to be able to relate detection events exactly to the drive cylinder length system, the possibility is provided that the corresponding cylinder has a cylinder sensor to detect a parameter that depends on the length system of the at least one drive cylinder, especially an angle, an angular difference or a perimeter length and / or a perimeter difference. In order that, alternatively or additionally, the position of the processing tool can be accurately detected, a position sensor can be assigned to the hdo and / or the actuating cylinder, which detects, for example, the position of the processing tool. processing or angle of the processing cylinder.

In the following, the invention is explained in more detail by means of a drawing which represents only an exemplary embodiment. In the drawing it shows:

FIG. 1 shows a method according to the invention and a device according to the invention in a schematic representation.

Figure 2 shows the procedure and the device in a flow chart representation.

1 shows a device 1 for processing a material tape 2 in the form of a packaging material tape of a packaging material laminate. As for the packaging material laminate it is a cardboard / plastic laminate comprising a cardboard layer, an aluminum layer and printed outer polyethylene layers. The material tape 2 can be unwound by a roller or supplied to the device 1 in another way. The material belt 2 is transported in a straight line through the device 1 shown and preferred in this regard. However, this is not mandatory, although it simplifies representation. In the case of the device 1 represented and preferred in this sense, the material belt 2 is driven by means of a drive cylinder 3, for which the material belt 2 is guided by a cylinder slot 4 between the drive cylinder 3 and a pressure cylinder 5. The cylinder groove 4 is so narrow that friction drag is provided between the drive cylinder 3 and the material belt 2. The drive cylinder 3 is driven by a drive 6, especially by an electric motor drive.

In this regard, the material belt 2 is transported to the right and guided, in this respect, so that it passes in front of a sensor 7 in which, in the case of the device 1 represented and preferred in this sense, it is treated of an optical sensor 7. If necessary, however, other sensors and / or more sensors may also be provided. Sensor 7 is provided in such a way that it recognizes on the material tape 2 registration marks 8 provided in the form of print marks when these pass through sensor 7. After the material tape 2 has passed through sensor 7, the material tape 2 arrives at a processing equipment 9 with a processing tool 10. In the case of the device 1 represented and preferred in this sense, it is a processing equipment 9 to divide the material tape 2 into isolated cuts, They can be used as cuts of packaging material to form packages, especially to fill them with food. For cutting the cuts of the material tape 2, the processing equipment 9 presents a processing tool 10 in the form of a processing cylinder with two cutting dies 11. The processing cylinder rotates with the transport direction T of the 2, so that the cutting blades 11 are guided so that they pass in front of a stationary cut 12 provided on the other side of the material belt 2 and, in this regard, they separate or cut the material belt 2 transversely with respect to the transport direction T. The processing tool 10 is driven by a drive 13, which in the present case is configured as an electric motor drive.

Alternatively or additionally, however, other processing tools may be provided which, for example, print, puncture, punch, fold or stamp material tape 2. In addition, crease lines may also be used in place of print marks, stampings, perforations, material differences or other characteristics of the material tape 2 as registration marks 8, In this regard, if necessary, it can be it is convenient to use a different sensor from the optical sensor 7.

The actuation cylinder 3 and the processing tool 10 are assigned a cylinder sensor 14 and a position sensor 15, which detects the position of the corresponding cylinders 3, 10 and transmits this position in the form of an S signal to a evaluation 16. The sensor 7 that detects the registration marks also transmits a signal S to the evaluation equipment 16 when a registration mark 8 passes the sensor 7. Thus, the evaluation equipment 16 can compare the processing position of the tool 10, by detecting a registration mark 8 or the processing position of the processing tool 10, which corresponds to a detection event of a registration mark 8, with a processing position, predetermined for the detection event , of the processing tool 10. If, in this sense, a deviation between the actual and the default processing position is determined, by means of the regulation 17 a regulation intervention is carried out which influences the drive 13 of the processing equipment 9 so that the corresponding deviation of the processing positions is reduced or increased as far as possible. In the case of the method represented and preferred in this sense, this is carried out by means of an acceleration or a delay, by way of impulse, for a short period of time, of the speed of the processing tool 10.

The evaluation equipment 16 can also determine, by the consecutive detection events of registration marks 8 by means of the at least one sensor 7, a speed parameter that depends on the tape speed of the material tape 2 in the area of the at least one sensor 7. The evaluation equipment 16 relates the belt speed with the length system of the drive cylinder 3, setting the angle, around which the drive cylinder 3 has continued rotating between two detection events, in relationship to detection events. Thus, it can be determined whether the expected distance of the registration marks 8 in terms of time and / or place of the material tape 2 coincides with the distance, actually determined, of the registration marks 8 also in time and / or length of the material tape 2. If this is not the case because, for example, the registration marks 8 do not have the predetermined distances, a displacement occurs during the transport of the material tape 2 or an expansion occurs of the material belt 2, by means of a control equipment 18 the speed of the processing tool 10 can be correspondingly adapted. In addition, separately from this, a regulation of the processing position of the processing tool 10 is carried out. Both, the regulation and the control, generate adjustment variables, which if necessary act by overlapping each other on the drive 13 of the processing cylinder 10 of the processing equipment 9.

Figure 2 shows the procedure described above in somewhat more detail. The same components are therefore characterized with the same references. As a guide quantity W, a speed of the processing tool 10 (set point) can be predetermined and, if necessary, can be justified by a particularly constant offset (compensation). In this way, the speed of the processing tool 10 can be predetermined correspondingly to the speed of the drive cylinder 3 for the drive of the material belt 2. A regulator R outputs an adjustment quantity U by means of the corresponding guide quantity W; accordingly, the drive of the processing tool 10 is actuated.

When only a deviation occurs between the default processing position of the processing tool 10 and the actual processing position of the processing tool 10 for a registration mark 8 detection event by sensor 7, the comparison unit D1, in which data E on the detection event and P data on the position of the processing tool converge, sends a signal S, which depends on the absolute value and the forecast of the deviation, to a position control unit PR , which adds an adjustment quantity U corresponding to the adjustment quantity U leaving the regulator R. When, alternatively or additionally, the effective tape speed, determined by the detection events of the registration marks 8 by the sensor 7 , does not correspond to the belt speed as would be expected from the speed of the drive cylinder 3, the comparison unit D2, in which it conve Data E on the detection event and data L on the length system of the drive cylinder 3 independently of the absolute value and the forecast of the deviation, sends a signal S to a calculation unit B, which by means of the corresponding signal S calculates a correction speed, which is then outputted as a guide quantity W to a correction speed regulation device KR, which, for its part, outputs an adjustment quantity U which is added to the adjustment quantity U which has already been previously determined.

A gate control T receives data E on the detection events and determines, by means of these and, if necessary, additionally by means of a belt speed parameter, a window as a function of time and / or the position of the material belt, window in which to wait for the next detection event, and transmits the data in question as TS gate control data to sensor 7. Outside this window, no detection is implemented, or the corresponding detection event is no longer processed as described.
