Definitions

  • the invention relates to a method and a device for the stripping of laminated film blanks, which are provided in a cover film glued to a backing adhesive layer with a carrier paper with incisions which form an advertising lettering or advertising graphic designed for self-adhesive attachment to an advertising surface.
  • the film cuts on a branching of a predetermined transport direction are influenced in cooperation with a transfer device with a deflection edge in such a way that with each film cut the film remainder for transfer to a remainder roll in a branch Transfer direction is withdrawn from the backing paper, while the backing paper with the advertising lettering or advertising graphic remaining on its top is removed in the predetermined transport direction.
  • the leading edge of each film blank is cut obliquely at an obtuse angle by means of a cutting device before the deflection edge is reached, so that the top of the cover film over the underside of the backing paper protrudes forward in the transport direction.
  • the quality of the bevel cut initially made on the leading edge of each film cut results in a significant influencing variable for a trouble-free removal of the cover film or. the remainder of the film from the backing paper in cooperation with the transfer device with the deflection edge.
  • the peeling is the more problematic, the thinner the cover film compared to the backing paper and the less it is initially possible to stick the cover film so strongly to the pad of the transfer device via its adhesive layer on the back that the for removing the cover film in Interaction with the deflection edge required tensile forces can be generated in the required amount at all.
  • the invention has for its object to develop the known stripping of laminated film blanks in such a way that while maintaining the greatest possible protection of the on the backing paper when the cover film is removed or. of the remainder of the foil or advertising graphic, it is not necessary to make an oblique cut on the leading edge of each foil blank.
  • a cutting device for the stripping of laminated film blanks, with which a dividing line running transversely to the transport direction from the underside into the carrier paper with a maximum of up to at a leading edge region of each film blank at a distance from its leading edge a cutting depth reaching into the underside of the cover film is cut.
  • the leading edge region of each film cut is then taken over by a clamping device of the transfer device in order to cooperate with a deflecting edge to cover the cover film or. remove the film residue from the backing paper for transfer to a remainder roll, while the backing paper with the advertising lettering or advertising graphic remaining on its top is removed in the originally specified transport direction.
  • the removal of the cover film resp. the remainder of the film from the backing paper can thus be introduced without problems and continued until the remainder of the film is taken over by the remainder of the roll.
  • the device therefore also comprises a transport device (not shown) with which the film blanks 3 consisting of a cover film 1 and a carrier paper 2 are transported in a predetermined transport direction 4.
  • the cover film laminated onto the backing paper via a layer of pressure-sensitive adhesive is provided with incisions which form an advertising lettering or advertising graphic which remains on the backing paper when the cover film or.
  • the film remainder adjacent to the incisions in the interaction of a transfer device 5 with a deflection edge 6, is pulled off the carrier paper in a branched transfer direction 7 as soon as a dividing line has been cut into the carrier paper of a leading edge region of the film cuts by means of a knife 8 of a cutting device 9.
  • the cutting device 9 is formed with a knife carrier 10, in which the knife 8 is at an insertion gap 11 for the leading edge region 12 of each film blank 3 is arranged such that a dividing line running transversely to the transport direction 4 can be cut into the carrier paper 2 from the underside with the knife 8.
  • the knife carrier 10 is moved back and forth in the direction of the double arrow 13.
  • the leading edge region has first been moved so far into the insertion gap 11 that a predetermined distance from the leading edge of the relevant film blank has been obtained for the line of action of the knife 8. Then it was still clamped by a clamping device, which is designed with a pull-off bar 14 and a relatively movable clamping bar 15.
  • the pull-off strip 14 is provided with a tip for forming the deflection edge 6, in which two guide surfaces for the cover film 1 and the film rest 16 of each film blank 3 meet.
  • the guide surfaces run parallel to the predetermined transport direction 4 and to the transfer direction 7 branched therefrom.
  • the clamping strip 15 can be moved from the underside of the carrier paper 2 against the guide surface parallel to the transport direction 4, so that the relevant film blank 3 can be clamped against the pull-off strip . This clamping is released again as soon as the leading edge area 12 has been transferred to the transfer device 5 after the cutting line has been cut into its backing paper 2 and after the cutting device 9 has been moved out of the path of movement of the film blank 3 in question.
  • the transfer device 5 is for further transport of the formed from the carrier paper 2 in cooperation with the deflection edge 6 peeled off film residue 16 to a residual roll (not shown). For this purpose, the transfer device is moved from the takeover position shown in FIG. 2 in the transfer direction 7.
  • the transfer device 5 has a clamping device which is designed with a clamping bar 17 and a clamping roller 18.
  • the pinch roller 18 is connected to the pin bar 17 on an axis of rotation 19 to enable the pinch roller to pivot relative from the relative position shown in solid lines in FIG.
  • the dividing line 20, the depth of cut of which should extend at least to the underside of the cover film 1 and expediently also includes a scoring of this underside of the cover film, ensures that the remainder of the film with the provision of a sufficiently large tensile force by the clamping force of the clamping device initially without any risk of damage the advertising lettering or advertising graphic remaining on the carrier paper can be subtracted from the carrier paper.
  • the transfer device As soon as the remainder of the film is taken over by the remainder roll and the clamping device of the transfer device 5 for one Release of the thus clamped edge region 12 has been released, the transfer device remains in a position relative to the pull-off bar 14 in which the absorption of the film residue on the remainder roll is not hindered.
  • the transfer device is only brought back into the position shown in FIG. 2 in the direction of arrow 7 'after a dividing line 20 has been cut into the carrier paper of its leading edge region 12 during a next cut of the film.
  • the cutting device has also previously been brought back into the path of movement of this next film blank.
