Definitions

  • GB-A-1400684 describes a device for applying an adhesive strip to the outer end of a reel.
  • this facility a support beam, which is integrated in a cutting roller; there is a holding slot for an adhesive strip below the supporting beam; the device also has a knife, which is provided with its cutting edge directly below the holding slot, and the support beam is rotatably arranged about an axis parallel to its longitudinal axis.
  • This device serves to connect two paper webs to one another.
  • the invention relates to a device which is used to prepare a paper roll for a later connection process.
  • the object of the invention is therefore to provide a device in which the individual processes are carried out essentially by machine.
  • This object is achieved with an adhesive tape which is essentially coated on one side with adhesive and which only has a further adhesive layer on its other side in the region of one longitudinal edge, in accordance with a device defined by the features of claim 1.
  • the guide roller is in the vicinity of the reel to be replaced, so that the end of the web from which the reel is wound can be knocked over the guide roller.
  • the end of the web is then cut off at a certain point, at which the adhesive tape held in a slot in the beam is also adhered to the new web end by a holding surface held by a supporting beam.
  • the adhesive strip sticks out only with the part out of the slot, the part of the adhesive surface of which is exposed for attachment to the web, ie in general is first freed of a cover film. This end is brought into the vicinity of the contact surface by a blowing device, the adhesive strip being deformed at an angle in cross section.
  • the web end H detached from the drum C lies above the guide roller 2 and hangs down here on its left side.
  • the guide roller which is designed as a hollow roller, has a rubber-elastic jacket 22 made of plastic.
  • a pressure surface 5 which is formed here by a strip made of rubber-elastic material.
  • This support beam is arranged parallel to the central axis of the guide roller 2 and the spool C and has a pivot axis 19 that also has this direction.
  • a holding slot 6 under the box-shaped carrier 11 and a knife 7 provided with a cutting edge 8, which is designed as a spring steel angle.
  • This knife is brought into the cutting position by means of a pressure hose 12.
  • the knife is fastened to the supporting beam 4 by means of a clamping strip 13.
  • Below the knife 7 there are blowing channels 9 with openings 10 for blowing air.
  • Further blowing channels 15 are located below these blowing channels and are connected to a central air channel 14, which also extends parallel to the central axis of the guide roller 2.
  • a guide surface 16, which generally consists of thin sheet metal, is arranged below the blowing channels 15. As shown, the web end H is held in a position suitable for cutting by this guide surface. It also facilitates threading the paper web and unwinding several meters of paper web from the reel.
  • An adhesive tape is used which is essentially completely covered on one side by an adhesive layer which is covered by a cover film D divided in the longitudinal direction of the adhesive tape.
  • the adhesive tape has a narrow adhesive strip near its one longitudinal edge, which consists of an adhesive layer F and a cover film E.
  • the adhesive tape A is shown in the position in the slot 6, in which it is after the suction (6) and the blowing up of the part already freed from the cover film through the blowing openings 10.
  • the cover film is only removed when the adhesive tape has been completely sucked onto the surface 5 and 6.
  • the nozzles 10 blow the surface 5 is vacuumed so that the adhesive tape lies directly on the surface 5.
  • the adhesive tape can then be connected to the end of the web in this position, the unnecessary End of web H is cut off by knife 7.
  • the plastic jacket 22 of the guide roller 2 must also be provided for this purpose.
  • a very suitable plastic is polyurethane.
  • FIG 3 shows the position of the adhesive tape after the web end has been rolled back onto the reel C.
  • the cover film E of the small adhesive tape has also been removed, so that the end of the web by means of the adhesive tape A could be attached to the drum C tightly.
  • the adhesive tape A still carries the second cover film part D. Shortly before the actual splice process begins, this cover film part is then finally removed.
  • the blown air channels 15 serve to guide the web end H into the correct position and down without human help.
  • the guide roller 2 is fixed (but rotatable about its central axis) and the approach of the guide roller 2 and drum c takes place through the storage of the drum C, which can be adjusted in the horizontal direction by means of the spindle 27.
  • the actual bearing point 26 of the drum has an incline so that its bearing axis always has a certain position with respect to the drum bearing.
  • This bearing 25 is located on a reel 24. Preparing the adhesive seam on a reel is the most difficult case; usually the drum is placed on a stand with a sloping track with a crane.
  • the contact surface 5 is essentially at the same level as the central axis 18 of the guide roller 2.
  • a deflector plate 33 is also provided for the web end H, wherein the web end can be removed from the guide roller 2 by means of blowing channels 31 connected to a central air duct 30. Additional blowing openings of the air duct 30 direct air flows essentially tangentially to the guide roller in its lowermost region, so that the web end H has to slide along the guide surface 33.
  • FIG. 5 shows a detail of how the drum C looks before the processing operation with the adhesive tape.
  • the left end of the web is shown here, which is attached to the circumference of the reel C by means of adhesive tape I.
  • a supporting beam is also possible, which can be pivoted about a central pivot axis. Accordingly, the contact surface is then also curved with a center of curvature that lies in this pivot axis.
  • the adhesive tape can also be attached to the end of the web, which is to be used when the diameter of the guide roller would have to be kept relatively small.
  • Fig. 4 it is also shown that the guide roller 2 can be movably mounted on side pivot arms (shown in dash-dot lines). Further swivel arms 38 connected to these swivel arms and shown in dash-dotted lines then allow the support beam 4 or the pressing surface 5 to be swiveled towards the guide roller 2 by means of the hydraulic lifting elements indicated.
  • the guide roller 2 can be provided with holes in its jacket, so that the web end can be sucked onto the jacket surface of the guide roller 2 by means of a vacuum applied inside it. If you then bring the reel C in a position in which it rests on the guide roller 2, by rotating the reel C by means of the guide roller, which is coupled to a motor, clockwise the end of the web along the outer surface of the guide roller 2 to the guide surfaces 16 and 33 are performed. In the opposite direction, the adhesive strip A is then firmly connected to the drum.
  • the whole arrangement is advantageously to be provided in such a way that the guide roller is arranged in the lower quadrant of the drum C, it preferably being arranged so deep that the common tangent of it and the drum C of the largest possible diameter runs essentially horizontally.
  • a drum wagon which preferably has an inclined plane as a holding surface, so that the drum rests against the guide roller 2 with a certain contact pressure due to this inclination.
  • this trestle could also have levers which brake or push the axis of the drum by pneumatic lifting elements, so that one could generate a controlled contact pressure of the drum C on the guide roller 2.
  • the general point of view is that the arrangement can be operated by the staff without catwalks.
  • the adhesive tape is advantageously placed in the slot 6 with a transport belt, e.g. Flat belt, drawn in.
  • a knife blade 20 is provided which runs completely parallel to the plane of the slot 6 and is also arranged to be movable in this direction alone.
  • the knife is held by a guide bar 23, which is guided in a dovetail guide, and by guide blocks 28, which are screwed onto the knife. These guide blocks are guided in obliquely arranged slots 29 of the guide bar 23.
  • suction openings 40 which lead from the hollow support 11 to the contact surface 5 and pass through it, are also shown. Furthermore, there are also the blowing openings 41 which are connected to the blowing air duct 42 are, which is sealed by means of seals 43 against the support beam. Further suction openings 45 of the hollow carrier 11 can be provided in order to fix the adhesive strip in the slot 6. However, this is also possible (for example, if a hollow beam 11 is not used) by means of a pressure hose 21. Instead of the guide bar 23, this knife could also be used to actuate the knife 20 if it has a pressure bar at its end facing the pressure hose - as shown in dash-dotted lines shown - would have. The knife would then be able to be returned to the rest position by ribbon springs 46, as also shown in dash-dot lines.
