Description

 Supply roll with marking, process for working with flat and / or strip material wound on supply rolls and system for handling with

 Flat and / or strip material

The present invention relates to a supply roll having a roll core and flat and / or strip material which is supported by a plurality of windings of the roll core.

Such stock rolls can be used for example in the field of packing technology. Apparatuses are known which provide uninterrupted flat and / or strip material in order to wrap articles with the flat and / or strip material and to combine them in this case. For example, the flat and / or strip material may be formed as a shrink film, wherein a plurality

Beverage containers enveloped by shrink film and to containers

be summarized.

If the supply of flat and / or strip material of a roll is exhausted, the roll must be replaced by another roll with new flat and / or strip material in order to continue a packaging process and preferably to perform uninterrupted. Devices for an uninterrupted packing process as well

corresponding stock rolls that can be used for an uninterrupted packing process, are known for example from DE 195 22 1 10 A1. In the device known from DE-application two parallel shafts are provided, sit on which supply rolls. From the supply rolls is

Shrink wrap unwound and placed around articles. The articles then pass through a shrink tunnel. If the supply of shrink film of a role is exhausted, so shrink film is another roll to the tape supply of the first roll means

Welded ßens connected.

If the shrink films of two roles are to be connected by means of Verschwei ßens, this is first deduct a free end of a new role and move for the purpose of welding in the direction of the other role. Frequently the position of the free end portion unknown, so that the new role must first be manually rotated or oriented, whereupon the free end portion is moved in the direction of the other role, to weld this with shrink film of the other role. With automated implementation, this can be associated with problems. Manual alignments are cumbersome and associated with human resources.

The object of the invention is therefore to provide a supply roll, can be replaced with the simplified manner and while avoiding problems already used up supply roll. It is also an object of the invention to provide an at least partially automated device or a method for handling flat and / or strip material, by means of which supply rolls can be simplified and replaced with at least largely avoiding problems.

The above objects are achieved by a supply roll, a method and an apparatus comprising the features in claims 1, 12 and 18. Further advantageous embodiments are described by the subclaims.

The invention relates to a supply roll comprising a roll core and flat and / or strip material which is supported by a plurality of windings of the roll core. The roll core can be formed for example by cellulose or plastic and have a hollow cylindrical shape. If the supply roll is used in the field of packaging technology, the flat and / or

 Band material be formed for example by shrink film or stretch film.

Furthermore, the supply roll has at least one function marking, which is formed on an outer free end region of the flat and / or strip material, so that information about the relative position of the free end region can be visually recognized via the at least one function mark. The functional marking can be designed as an adhesive marking or as an adhesive marking and thus possibly on at least one broad side surface proportionally or completely comprise an adhesive application. Thus, an adhesive bond can be formed between the at least one functional mark and the outer free end region.

The invention is not limited to embodiments with only one

Function mark limited. Thus, it is also conceivable that in various embodiments two or more than two function markings are provided, which are each formed in a defined relative position at the free end region of the flat and / or strip material of a supply roll.

Since the at least one functional mark is formed in a defined relative position on the outer free end region of the flat and / or strip material, conclusions about the actual position or the actual orientation of the free end region can be made by optically recognizing the at least one functional mark.

In particularly preferred embodiments, it can also be provided that the at least one functional marking comprises one or more adhesive markings, wherein a respective adhesive bond exists between the one or more adhesive markings and the free end region of the flat and / or band material. Further, it may be that the supply roll comprises at least one adhesive bond, which sets the free end region of the flat and / or strip material at an outside of the free end region lying outside lying position of the flat and / or strip material. In this case, the respective adhesive bond of the adhesive marking the free end region of the flat and / or strip material at the free end region adjacent au outer lying position of the flat and / or strip material set. The adhesive marking or the

Adhesive marking can thus be bonded both to the free end region and to the outer layer of the flat and / or strip material. If more than one adhesive marking is present, then all adhesive marks of the respective

 Supply roll set the free end region at an outer position of the flat and / or strip material adjacent to the free end region. Advantageously, the free end region can retain its relative position on the roll as a result of the bonding. The risk of unintentional Abwickeins of flat and / or sheet material from the supply roll is reduced.

It is also conceivable, however, that the free end region itself is adhesively bonded to the layer adjacent to the free end region of the flat and / or strip material. Thus, the pointing in the direction of the adjacent position side of the free end portion and the adjacent layer at least one adhesive connection may be interposed. It is also conceivable that the adhesive marking or a

 Wide side surface of the adhesive marker in the direction of the outer layer lying flat, so that the connection between the outer-lying position and the

Adhesive marking a lower adhesive force than the connection between the free End region and the adhesive mark has. In particular, the adhesive marking can taper in the direction of the outer layer. Have proved successful here

Embodiments in which the adhesive marker is opposed to two

Has broad side surfaces which have a triangular shape and one of which is designed as an adhesive surface. The free end area can hereby

advantageously be easily removed, wherein the connection between the adhesive marking and the adjacent outer layer is achieved and the

Connection between the adhesive mark and the free end area is maintained.

It may also be the case that the at least one function mark has at least one identification which defines the function mark

 Assigning the rotational position with respect to the terminal edge of the outer free area. Here, the at least one identifier, for example, a

comprise transparent and preferably rectilinear viewing window, via which the profile of the terminal edge of the outer free end region can be optically detected. Practice has shown that functional markings, especially if they are designed as adhesive mark, can also be applied manually or manually to the free end region. In addition, it may be that

Connecting or forming the function mark on the free end region is made automated. In addition, further markings or optical markings come in

Consider, in order to assign the at least one function mark, if necessary, a certain rotational position with respect to the end edge of the outer end free end region. For example, a symbolism such as an arrow or the like

be provided, which refers with the aid of the end edge to the corresponding specific rotational position for the at least one function mark.

In addition, at least one function mark can be at least one

Identification, which assigns the at least one functional mark a central position with respect to the longitudinal extent of the supply roll. A marking over half the amount of the longitudinal extent can in this case be applied to the supply roll or onto the flat and / or strip material, preferably along a winding course. With the aid of the marking, the at least one functional mark can then be applied at least approximately centrally on the free end region of the flat and / or strip material of the supply roll. A transparent viewing window can be provided as an identifier to the function mark the assign central position. Again, a symbol, such as an arrow or the like may be provided, which refers with the aid of the mark on the corresponding central position for the at least one function mark.

The supply roll can also comprise an RFID transponder on which information about the supply roll is stored. For example, information about the number of turns, the nature of the respective flat and / or strip material, the amount of the longitudinal extent of the supply roll and / or further information can be stored on the RFID transponder. The information from the RFID transponder can then be read out via a corresponding RFID reader and possibly displayed on a display or on a display and / or used for working parameters of the packaging machine. The RFI D reading device can be arranged in the region of an installation position for the supply roll or in the region of a holding mandrel. It is also conceivable that a

Handling device, which places the respective supply roll on a retaining pin, the RFID reader carries. The RFID transponder can on the flat and / or strip material of the respective

Fixed supply roll and be glued, for example, on the flat and / or strip material of the respective supply roll. In particularly preferred embodiments, the RFID transponder may be formed as part of the function mark. It is also conceivable that the RFID transponder in the free end of the flat and / or

Band material is embedded or that the flat and / or strip material formed in the free end region of a pocket which receives the RFID transponder.

In general, it may be advantageous if the function marks so

are equipped and used to convey and / or provide information and / or data on the film rolls a packaging machine and / or handling device. As such a suitable information carrier imprinted optical codes or the aforementioned RFID transponder can be used.

It is also conceivable that the at least one function mark has a QR code which, in coded form, has corresponding information, as previously mentioned, for the supply roll. In addition, further codings, such as barcodes, by means of which information can be held to the supply roll. In particularly preferred embodiments, at least one

Function mark consist of a pressure applied in a defined relative position on the free end area print job. The print job may in this case comprise at least one marking formed as a line, which extends parallel to a terminal edge of the outer free end region of the flat and / or strip material. The line may extend proportionally or completely over the entire width of the flat and / or strip material. In particular, the print job can be designed such that it refers to a central position with respect to the longitudinal extension of the supply roll. Thus, with the help of the print job and its optical

Detecting an axial alignment of the supply roll when inserted into a mounting position to be described below and if necessary corrected, so that the axial alignment of the supply roll in the respective mounting position corresponds to a desired orientation.

The invention also relates to a method for dealing with

Supply rolls wound flat and / or strip material. In the context of the method, at least one function mark is applied to an outer, free end region of the flat and / or strip material of a supply roll in a defined relative position. The at least one function mark can be designed according to the preceding description. Furthermore, the at least one functional marking may comprise an adhesive marking, which is adhered to the free end region of the flat and / or strip material or has an adhesive application, by means of which adhesive application the adhesive marking is connected to the free end region. The bonding of the adhesive marker to the free end region of the flat and / or

Band material can be automated or manual. The adhesive application may be formed as part of the adhesive label.

In the context of a further method step, which may be followed in time by the application of the function marking to the free end region, the supply roll is placed on a holding mandrel. For example, a handling device can be provided which rests the supply roll on the retaining pin. The retaining mandrel can be formed as part of an installation position of a packaging machine and, if necessary, rotated or actorically rotated for unwinding the flat and / or strip material from the respective supply roll.

In a further method step, the position or position of the at least one function marking is optically recognized. For this purpose, optical sensors and For example, one or more camera systems may be provided in order to optically recognize the position or position of the at least one function mark. It is conceivable, for example, that the position or position of the at least one functional mark is optically recognized and the supply roll is then placed on the holding mandrel. For example, a handling device may be provided, which has an optical sensor or a camera system, detects the position or position of the at least one function mark and temporally thereto the supply roll touches the holding mandrel, so that the free end region or the at least one function mark a certain Has orientation or position. However, it is also conceivable that one or more optical sensors are positioned in the region of the retaining mandrel or in the region of a respective installation position for the supply roll and recognize a position of the at least one functional mark after placing the supply roll on the retaining mandrel. If the position of the at least one function mark does not coincide with a predetermined desired position, the holding mandrel can rotate the supply roll until the position of the at least one function mark with a predetermined desired position

matches. Thus, in a further method step, the free end region is aligned as a function of the optical recognition. The free end region can be aligned by a rotation of the retaining mandrel, on which the respective supply roll is seated.

Practice has shown that function markings can be easily recognized if the function mark on a broad side facing away from the supply roll areas with high contrast. Thus, at least one first recognizable region of the at least one functional marking may be formed black and at least one further region, which optionally adjoins the first region, may be white and / or transparent.

In a further method step, the free end region is gripped and withdrawn from the supply roll. For this purpose, for example, a suction and / or

Gripping device or a suction rod may be provided which detects the free end region via negative pressure and leads away in the direction of the supply roll. Since this step takes place after the at least one functional marking or the free end region has been aligned, the free end region can be received in a targeted and problem-free manner by the suction and / or gripping device and pulled off in the direction of the respective supply roll. In packaging machines, the free end can on this following with already running in the packaging machine flat and / or strip material, which is possibly unwound from another supply roll a further mounting position, are connected. For this purpose, for example, a vertically movable welding rod can be provided, which is the free end against the already in the

Packaging machine guided flat and / or strip material moves.

It is also conceivable that the at least one functional mark at least approximately centrally and / or with a certain rotational position with respect to a

End edge of the outer free end portion is applied to the outer end lying free end region. As already mentioned above, the at least one function marking for this purpose can have one or more identifiers in order to connect the at least one function marking to the free end region at least approximately centrally and / or with a specific position or rotational position.

In particular, embodiments have proven in which the at least one marking is formed by a transparent viewing window with T-shape. The at least one marking can also be used for a check of a correct seat or a correctly defined relative position of the at least one

Function mark serve on the free end of a respective supply roll.

In addition, it may be that at least one function mark as

Adhesive marking is formed, which is connected to a free end region of the flat and / or strip material and with the free end region adjacent position of the flat and / or strip material and in particular glued, so that the at least one function marker or adhesive mark on the free end the adjacent position of the flat and / or strip material sets. In particular, embodiments have proven in which the adhesive marking over a

Adhesive bond with the free end portion and the adjacent layer is connected such that an adhesive force of the adhesive bond between the free end portion and the adhesive mark is formed greater than an adhesive force between the adjacent layer and the adhesive mark. Thus, the free end portion can be easily withdrawn from the supply roll or the flat strip material, whereas the at least one function mark or adhesive mark remains connected to the free end region.

In particularly preferred embodiments it can be provided that one or more functional markings on the free end region in defined

Relative position to be printed. A print job can hereby according to previous description to conceivable embodiments of the supply roll according to the invention be educated. In particular, it may be that a line is printed on the free end portion which is parallel or at least approximately parallel to one

End edge of the free end region extends.

The invention further relates to a device for handling wound on stock rolls flat and / or strip material. The device comprises a device by means of which at least one function mark can be applied to an outer outer free end region of the flat and / or strip material of a supply roll in a defined relative position. By way of example, the device can comprise a handling device, by means of which a function marking designed as a sticking mark can be applied to the outer, free end region

can be applied.

In addition, the device, which optionally as a packaging machine

may be formed, at least one and preferably two mounting positions, which are provided for the rotational recording of supply rolls with flat and / or strip material. The at least one mounting position may be assigned a retaining pin, on which the supply roll is plugged. If necessary, the retaining mandrel can fix the supply roll in a clamping manner by increasing its cross-sectional diameter.

In addition, a handling device for inserting the respective supply roll is provided in the at least one installation position. For example, several supply rolls may be arranged on a pallet, received by the handling device and inserted into the respective installation position. In front

Receiving the supply rolls by the handling device, the free end region of the respective supply roll may already have the at least one function mark or be connected to an adhesive mark. The device also comprises an optical detection device, by means of which a position of the at least one function mark can be detected. The optical detection device may, for example, comprise at least one camera system.

Also, one or more means are provided, by means of which the free

End region of a respective supply roll can be aligned in dependence on the optical detection, so that the free end region of the respective supply roll in the installed position has a predetermined position. For example, the one or more means may be formed as a holding mandrel or comprise a retaining pin, on which the respective supply roll is clamped. In order to align the free end region, the retaining mandrel can be rotated by a certain amount until the free end region or the at least one functional marking reaches a desired position. In preferred embodiments, the device may comprise at least one

 Include printing station, by means of which at least one function mark can be printed on the outer free end region of the flat and / or strip material of a respective supply roll in a defined relative position.

For identical or equivalent elements of the invention, identical reference numerals are used. Furthermore, for the sake of clarity only reference numerals in the individual figures that are required for the description of the respective figure. The illustrated embodiments are merely examples, such as

Invention can be configured and do not represent a final limitation.

Figure 1 shows a schematic view of an embodiment of a

Supply roll 5 according to the invention. The supply roll 5 has a roll core 6, which can be formed, for example, from cellulose or plastic and is designed as a hollow cylinder. Due to the hollow cylindrical shape, the supply roll 5 or the roll core 6 can be placed on a retaining mandrel 15 or by a

Handling device 10 is received and attached to a retaining mandrel 15 (see Figure 5).

From the roll core 6 flat and / or strip material 8 is supported with a plurality of windings. The flat and / or strip material 8 is formed as a shrink film 9.

Furthermore, the supply roll 5 comprises a functional mark 2, in the present case designed as an adhesive marking 3, which is defined with an outer free end region 7 of the flat and / or strip material 8 or the shrink film 9 in FIG

Relative position is connected. Insofar as the position of the function marking 2 is known or has been detected, conclusions about the relative position of the free end region 7 can be made. The supply roll 5 rests on a holding block 12, which has two lateral

 Stops 14 limits the freedom of movement of the supply roll 5 on the holding block 12. It is conceivable, for example, that the function marking 2 or adhesive marking 3 is applied to the supply roll 5 or to the free end region 7 of the supply roll 5, while the supply roll 5 rests on the holding block 12. It may also be that the supply roll 5 is placed on the support block 12, this already one

 Function mark 2 has and is used by the holding block 12 in an installation position EB (see Figure 6) of a packaging machine.

A combination of Figures 1 and 2 illustrates the relative position of the function marker 2 at the free end portion 7 of the flat and / or strip material 8 and the shrink film 9. Thus, the function marker 2 or adhesive marker 3 has a label 22, which is formed as a transparent viewing window 24 is and has a straight course. The adhesive marking 3 is connected to the free end region 7 of the flat and / or strip material 8 or the shrink film 9 in such a way that a End edge 18 of the free end portion 7 completely along the label 22 and along the transparent viewing window 24 extends. Since the function marking 2 or adhesive marking 3 itself is designed as an adhesive marking or on its the flat and / or strip material 8 facing broadside surface itself a

Adhesive application forms, the function mark 2 or adhesive mark 3 can be glued manually on the free end portion 7, so that the end edge 18 can be seen via the transparent window 24. The transparent viewing window 24 allows after connecting the function mark 2 or adhesive mark 3 with the free end portion 7 a check for a correct position of the function marker 2 or adhesive mark 3. If the end edge 18 in the transparent viewing window 24 can not be seen, then the function marker. 2 or adhesive marker 3 removed and, if necessary, again connected to the free end portion 7.

On the supply roll 5 or on the flat and / or strip material 8, a mark 16 is applied in approximately half the amount of the longitudinal extension of the supply roll 5 over a winding course. Furthermore, a combination of FIGS. 1 and 2 clarifies a specific positioning of the function marking 2 or adhesive marking 3 with respect to the marking 16. Thus, the function marking 2 or adhesive marking 3 has a further marking 20 which runs approximately perpendicular to the marking 22 and also as transparent Viewing window 24 is formed. Both markings 20 and 22 form a T-shape. Also the label 20 or as transparent

 View window 24 formed label 20 has a straight line. The functional marking 2 or adhesive marking 3 is applied to the free end region 7 in such a way or is in contact with the free end region 7 in such a way that the marking 16 runs along the marking 20 or along the transparent

Viewing window 24 of the label 20 extends. With regard to the longitudinal extent of the supply roll 5, the functional marking 2 or adhesive marking 3 is thereby placed approximately centrally on the free end region 7 of the supply roll 5. The marking 20 or the marking 20 designed as a transparent viewing window 24 also permits a check of the correct position or position of the function marking 2 or

Adhesive marking 3 after connecting to the free end portion 7. If the mark 16 in the transparent window 24 can not be seen, the function mark 2 or adhesive marker 3 can be removed from the free end portion 7 and placed again on the free end portion 7, so that the Mark 16 along the

Marking 20 or along the transparent viewing window 24 extends. If the position of the function marker 2 or adhesive marker 3 is detected, conclusions about the position of the free end region 7 as well as the position or dimensioning of the supply roll 5 can be made. A capture of the free

End area 7 after optical recognition of the function mark 2 or adhesive mark 3 and a removal of the free end portion 7 of the supply roll 5 are then easily possible.

FIG. 1 furthermore shows that the functional marking 2 or adhesive marking 3 fixes the free end region 7 of the flat and / or band material 8 at an outer layer 11 lying adjacent to the free end region 7 of the flat and / or band material 8. The functional marking 2 or adhesive marking 3 is thus adhered both to the free end region 7 and to the outer layer 1 1 lying, so that the free end portion 7 and the flat and / or strip material 8 can not be handled unintentionally. Due to the triangular shape of the functional marking 2 or adhesive marking 3, the adhesive force formed between the free end region 7 and the functional marking 2 or adhesive marking 3 is greater than an adhesive force which is between the outer layer 1 1 and the functional marking 2 or adhesive marking 3 is trained. The free end portion 7 can thus be easily removed, wherein the adhesive bond between the function mark 2 or Haftmarkierung3 and the outer layer 1 1 is released, the function marker 2 or adhesive marker 3, however, continue with the free end portion 7 of the flat and / or Band material 8 remains connected.

3 shows a further functional marking 2 or adhesive marking 3, as it can be used for various embodiments of a supply roll 5 according to the invention (see FIG. The function marking 2 or adhesive marking 3 of the embodiment of Figure 2 has a label 22, which of the

 Function mark 2 or adhesive mark 3 assigns a certain rotational position with respect to the end edge 18 (see Figure 1) of the outer free end portion 7. As well as the function marker 2 or adhesive marker 3 of

Embodiment of Figure 2 has the function marker 2 or adhesive marker 3 in Figure 3, a label 20, which the function marker 2 or

Adhesive marking 3 a central position with respect to the longitudinal extent of

Assigns supply roll 5. The functional marking 2 or adhesive marking 3 can be aligned centrally with the aid of the marking 16 (see FIG. The markings 20 and 22 are further each as transparent

Viewing window 24 is formed. The functional marking 2 or adhesive marking 3 of the embodiment from FIG. 3 also has an RFID transponder 25, which is permanently connected to the function marking 2 or adhesive marking 3. On the RIFD transponder 25 information on the respective supply roll 5, to which the adhesive label 2 is adhered, can be deposited. It is conceivable that on the RFID transponder 25

For example, information on the number of turns, the nature of the respective flat and / or strip material 8, the amount of the longitudinal extent of the supply roll 5 and / or further information are stored. It is then possible to read out the RFID transponder 25 by means of a corresponding RFI D reading device, which is not shown in the figures of the present patent application and can be arranged, for example, in the region of an installation position EB (see FIG.

Provided that information on the number of turns of the supply roll 5 is deposited on the RFID transponder 25, provision can be made for a packaging machine to be controlled after the RFID transponder 25 has been read out, taking account of the stored information. By possibly deposited number of windings, the packaging machine may possibly indicate a necessary replacement of the supply roll 5 or cause an exchange or replacement of almost completely applied supply roll 5 or perform automated.

The embodiment from FIG. 3 with an RFID transponder 25 is to be understood as an example. Thus it can be provided that the function mark 2 or

Adhesive marking 3 instead of the RFID transponder 25 or in addition to the RFID transponder 25 via codings information to the supply roll 5 is available. The codes can be used, for example, as a QR code, bar code and / or further

Coding be formed. It is also conceivable that the supply roll 5 is formed in the free end region 7 a pocket, by means of which an RFID transponder 25 is received and fixed at the free end region 7. The RFID transponder is with these conceivable

Embodiments do not form part of the functional marking 2 or adhesive marking 3. FIG. 4 shows a further functional marking 2 or adhesive marking 3, as may be used for various embodiments of a supply roll 5 according to the invention. The function marking 2 or adhesive marking 3 is formed almost completely transparent and further has markings 20 and 22, by means of which a predetermined relative position of the function marker 2 or

Adhesive marking 3 at the free end portion 7 of the flat and / or strip material. 8 refer. The markings 20 and 22 are in an embodiment of a

Function mark 2 or adhesive mark 3 formed according to Figure 4 as arrow representations 26. Alternatively, other symbols or further embodiments for the markings 20 and 22 may be provided to the corresponding

Relative position for the function marking 2 or adhesive marking 3 at the free

End region 7 and possibly to direct their central alignment on the supply roll 5.

Figure 5 shows a schematic view of another embodiment of a supply roll according to the invention 5. The supply roll 5 of the embodiment of Figure 5 forms as well as the supply roll 5 of the embodiment 1, a free end portion 7 with the end edge 18. The flat and / or strip material 8 of the supply roll 5 is formed as a shrink film 9. The flat and / or strip material 8 is carried by a roll core 6, which is seated on a holding mandrel 15 in an installed position EB (see FIG.

The functional marking 2 or adhesive marking 3 from FIG. 5 furthermore has a marking 20 which extends along an end edge 18 of the free end region 7 or of the flat and / or band material 8. By means of the marking 20, the functional marking 2 or adhesive marking 3 can be simply applied in a defined relative position to the free end region 7 of the flat and / or strip material 8 or

glued on. 5, the free end region 7 is fixed to an adjacent layer of the flat and / or strip material 8, so that the free end region 7 via the functional marking 2 or adhesive marking 3 on the supply roll 5 is held substantially immovable. Compared to the function marks 2 or

Adhesive marks 3 from Figures 1 to 4 has the function mark 2 or

Adhesive marking 3 several triangular markings 27, along the

 End edge 18 of the free end portion 7 are positioned. The function marking 2 or adhesive marking 3 can, with its triangular markings 27 in conceivable further embodiments, also be extended over or along the entire

Extending end edge 18. Due to the plurality of triangular markings 27, the optical

Detecting means 30 even with inaccurate axial placement of the supply roll 5 on the retaining mandrel 15 or inaccurate axial alignment of the supply roll 5 relative to the detection device 30 a respective position of the free end portion 7 recognize. The triangular markings 27 are to be understood in the present case merely by way of example. so that in various other embodiments, other markings or symbols may be provided by means of which the supply roll 5 and the free end portion 7 can be aligned with the aid of the optical detection means 30. FIG. 6 shows a schematic view of an embodiment of a

Device 100 according to the invention. The device 100 is provided for handling flat and / or strip material 8 wound on supply rolls 5.

The device 100 comprises a device 50 (see Figure 7), which is not shown in Figure 5 and by means of which the function mark 2 or adhesive marker 3 on the outer free end portion 7 of the flat and / or strip material 8 and Shrink film 9 can be applied in a defined relative position. The
