Description

cut. Before that, of course, are the camps 13 lower with the knife 16 accordingly.

After the winding roll 1 is provided on the front side with thorns for transport and hanging in the roll star the prepared winding roll can be conveyed to the unwinding point. Regardless of that, the Rolleur already has another winding roll in the one described Prepare ways that should be used for another unwinding point if necessary

Claims (1)

1 2 can be completely removed. Claim: This task is achieved through the application of the features from the characterizing part of the patent application Device for preparing packaged slogans solved Winding rolls made of web material for unwinding, 5 This measure makes it possible to use the Vorrichmit two axially parallel arranged at a distance from each other separated from the downstream processing level, set up drivable support rollers for a winding machine so that the roller without a lower roller, with one between the support rollers at the break the winding rolls for several roll changers Attacking winding roll, a pressure medium piston can prepare and also the complete packaging cylinder unit having lifting device, with ίο and paper waste easier with mechanical a frame with adjustable tools for the aids can be removed and then sorted the outer layers, and with a rack behind them with guides Cutting device for the leading edge of the web, also for the height-adjustable mounting of the cutting through characterized in that the frame (7) device for covering, separating the two sides the winding roll (1) arranged in pairs 15 ßenlayers of the winding roll and the straight cutting of the te guide rails (10, 11) and that on the edge to be glued. the one pair of guide rails (10) each higher. By accommodating the required adjustable bearings (12) parallel to the winding tool in the area of the device, the supporting rods (17, 18) running along the axis of the control roller are also rational for voltage. In addition, the waste can easily be separated from the outer layers and two auxiliary knives and new winding rolls can be provided by the free knife (15), which can be displaced along this for the protruding arrangement of the device.
(19, 20) for separating the frontal packaging The invention is arranged in the following on the basis of a recess, whereas along the other guide rail pair (11) bearing (13) of a transverse illustrated in this shows with reference to the drawing in more detail
carrier for a knife (16) of the straight cutting device 25 F i g. 1 is a front view of the device,
Device adjustable in height are provided. F i g. 2 a side view, F i g. 3 is a plan view One wrapped and with a few layers of protective paper provided winding roll 1 can, as FIG. 1 shows both 30 for example by means of a flat carriage 2 or a crane The invention relates to a device for passing over two support rollers 3, 4 and one with a pneumatic Ride of wrapped rolls of web material tables piston provided lifting device 5 brought for unwinding according to the preamble of the patent and by lowering it onto the two support rollers 3, 4 Saying. are placed, which by means of a drive device 6 Preparing wrapped paper rolls 35 are rotatable. up to now, printing has been carried out directly on the roller star even between the printing units by a roller winding roller 1, d. H. removing the vervon at the front Hand in time while a pack to be printed is done. For this purpose, a frame 7 is provided The winding roll runs out, done. Since the preparation of a side stand 8.9 in addition to the support rollers 3.4 vorgeseanderen Hen the winding roll on another star wheel 40. There are guide bars on these side stands 8, 9 the same operator is not possible, NEN 10,11 for height adjustment of bearings 12,13 for This sometimes resulted in considerable idle times for cutting devices 14,15,16 attached in pairs, the roller, which leads to an increase in the cost of the printing process. The bearings 12 are connected to one another by support rods 17, 18 duktes led. connected, wherein on the one support rod 17 two in From DE-OS 20 33 385 is already a device 45 in the form of circular knives trained auxiliary knife 19.20 to prepare, d. H. Unpacking of paper rolls to separate the front packaging from rolls known, with both the winding roll around a roller 1 of different sizes horizontally displaceable longitudinally Axis as well as about a vertical axis are superimposed. is rotatable. Mechanical aids to remove the By lowering the bearings 12 after the side- Packaging or the outer layer of paper and, for the most part, the setting of the auxiliary knives 19, 20, this pre The cutting of the beginning of the web is easy to do at this point, quite a complete device but not available. Using a tear strip inserted in the packaging The US-PS 33 51 299 shows a device of one of the packaging itself can be torn open lengthways and Initially designated type. The tool there consists of sleeve plugs 21, 22, which the end face a chisel for removing the winding roll 55 of the winding roll 1 in the core area from damage surrounding bandages. With a chisel, however, the protection can be removed. Removal of packaging material for paper wraps - Roll along with the motorized rotation of the support rollers 3, 4 not possible. Trained as crop shears means consisting of an electric motor and gearbox The straight cutting device is at a distance from the drive device 6, the packaging can now arranged for the tools. This known 60 to be settled. The device is primarily used to prepare by longitudinally moving the plow knife Metal band ties so that the tools can then use the cutting device 15 accordingly are designed accordingly. In this way, it is also not possible to remove the bad outer layers of the winding roll 1 borrowed to become a front-side packaging of winding rolls after the bearings 12 are correspondingly far remove. 65 have been lowered. The object of the invention is to provide a compact construction. The beginning of the material web 23 is now on a To create a device with which the roll packaging, the bearing 13 connecting worktop 24 and pulled In particular, of wrapped paper rolls, the edge of the material web is straight with the knife 16
