Definitions

  • the invention relates to an adhesive device according to the preamble of claim 1.
  • Gluing devices according to this invention are used in web printing machines. These printing machines print on continuous paper webs, which are wound up in paper rolls. Printing machines equipped with paper rolls are used where speed is important. This requirement applies to newspapers, magazines, and a variety of commercial print products. Speed is of paramount importance in the production of these printed matter. It influences an abundance of work steps.
  • the adhesive connection according to the invention can achieve an adhesive reliability of 99.4%.
  • the splice connections were carried out without interruption to the great satisfaction of the press operators. This success was achieved because the adhesive pattern according to the invention can be made without regard to specific tolerances in the dimensions of the web, the adhesive, the application of the adhesive and a protective cover of the adhesive layer.
  • the adhesive pattern can be applied to the paper roll early, especially before it is introduced into the printing press; it provides a reliable, fresh adhesive surface when the protective cover is removed from the adhesive pattern.
  • the gluing device can be operated effectively during operation. This reliability is of great importance to industry and has solved a long-standing problem.
  • the gluing device is constructed so that it has a so-called triangular shape or that of a double triangle, the base of the triangle being applied to the front edge of the new paper roll.
  • the corner of the triangle opposite the base of the triangle which is a considerable distance from the base, includes adhesive areas on both sides so that the adhesive connection can be secured on the roll by keeping the leading edge in place while the other side during the gluing process causes an adhesive splice with the outgoing paper roll, which is just feeding the rest of its paper web into the printing press.
  • an adhesive pattern is provided, which creates a precise adhesion between the adhesive device and the leaking old paper roll.
  • the surface is provided with a very pressure-sensitive adhesive which grips immediately and adheres to the end of the paper roll, so that it brings into play the remaining extensive adhesive pattern of the adhesive device.
  • the adhesive pattern is provided with blank areas so that the drive belts, with which the new paper roll is brought to the same rotational speed as the old paper roll, do not interact with or come into contact with the adhesive surfaces, which leads to destruction of the adhesive device and one would wipe out the gluing options.
  • a protective layer is provided above the entire adhesive surface and remains in its position until the adhesive device is prepared for the splice. This means that the adhesive surfaces are fresh and have no loss of their adhesive properties and do not previously absorb any contaminants such as lint, dust or the like.
  • the adhesive pattern according to the invention has a predetermined shape, size, adhesive areas; and covering the adhesive surfaces before splicing them together with adhesives prevents all the problems mentioned above and ensures a reliable splice connection at all times.
  • a printing press (FIGS. 1, 2) has a roll changer 10.
  • the roll changer 10 contains a paper roll 12 which is currently in use and is therefore also referred to as an outgoing paper roll. From it, a paper web 14 is drawn into the printing press.
  • the new or next paper roll 16, which is wrapped with a paper web 17, is arranged like the paper roll 12 on a roller star 18, so that the paper web 17 can later be spliced together with the paper web 14.
  • the splice is carried out by an adhesive device with an adhesive pattern 20.
  • Drive belts 22 cause the paper roll 16 to rotate so that the end of the paper web 17 can be detached from it at the same speed at which the paper web 14 is knocked off the paper roll 12 to achieve an effective splice.
  • 6 shows the almost unwound paper roll 12 and the new paper roll 16 with the adhesive pattern 20 which sticks to the end of the paper web 17 of the new paper roll 16 before the process of splicing begins.
  • 6 also shows a pressure roller 26 surrounded by a flexible foam sleeve or bristles and a cutting knife 28.
  • the paper web 14 is drawn into the printing press (not shown here).
  • the pressure roller 26 is provided for the paper web 14 against the paper roll 16 to press with a sufficiently large pressure so that the adhesive layer of the adhesive pattern 20 adheres.
  • the paper roll 12 and the paper roll 16 both rotate counterclockwise, which is indicated by arrows A and B.
  • the new paper roll 16 has an angular velocity such that the paper web 17 on the outer surface of the paper roll 16 moves at the same speed at which the paper web 14 is being drawn into the printing press.
  • the pressure roller 26 (FIG. 7) then moves against the paper web 14, while the new paper roll 16 and with it the adhesive pattern 20 move to the position at which the adhesive pattern 20 comes into adhesive contact with the paper web 14.
  • the new paper roll 16 and the adhesive pattern 20 applied to it are connected to the paper web 14 (FIG. 9); the cutting knife 28 is activated in order to separate the paper web 14 from the remnant which remains on the old paper roll 12 which is running out. This process takes place at very high speeds, i.e. a high rotation and feed speed.
  • the individual components of the adhesive pattern 20 are shown in FIGS. 3 and 4.
  • the adhesive pattern 20 contains paper which is strong enough not to tear under normal circumstances, but which is not strong enough to be easily torn as required when spliced together.
  • the adhesive pattern 20 (FIG. 3) has a construction of two triangles 30, each with a truncated corner 30A.
  • a base side 32 is the common base side of the two triangles 30, their width essentially corresponds to the width of the paper web 17 on which the adhesive pattern 20 is applied.
  • a strip 34 (FIG. 4) of a pressure-sensitive adhesive is applied to the rear side 29 of the base side 32.
  • the strip 34 is shaped such that the adhesive pattern 20 sticks to the front free edge 36 (FIG. 2) of the paper web 17.
  • the adhesive pattern 20 is to be applied to the new paper roll 16
  • a removable protective layer 38 which covers the pressure-sensitive adhesive strip 34, is removed so that the pressure-sensitive adhesive strip 34 is exposed; then the adhesive pattern 20 is glued onto the front edge 36 of the new paper roll 16.
  • the adhesive pattern 20 is attached to the upper layer of the paper web 17 by an adhesive tape (not shown) at the positions of the triangles 30, which are denoted by 40 and adjoin the truncated corners 30A glued on.
  • These adhesive tapes permit an adhesive connection of the triangles 30 on the surface of the paper web 17 of the new paper roll 16.
  • the front edge 36 and with it the adhesive pattern 20 are held firmly in their positions.
  • the front surface 31 (FIG. 3) of the adhesive pattern 20 is provided with a plurality of adhesive-coated surfaces which are arranged so precisely that contact with any other surface which is not desired is avoided, in particular contact with one of the drive belts 22, which accelerate the new paper roll 16 to a sufficiently high speed.
  • the non-coated surfaces also serve to allow air to escape during the splicing process. 3, viewed from left to right, has an adhesive surface 39, a non-adhesive surface 42, a narrow adhesive strip 44 and a non-adhesive surface 46. This is followed by a wider adhesive strip 48 and a non-adhesive surface 50.
  • a wide adhesive strip 56 covers the central region of the adhesive pattern 20.
  • the pattern of the adhesive and non-adhesive strips and surfaces is repeated on the right of the two triangles 30 and has the same reference numerals.
  • the non-adhesive surfaces 42, 46, 50 and strips 54 have a width and a length which is adapted to the drive belts 22 so that they do not touch the adhesive surfaces 39 and the adhesive strips 44, 48 and 52.
  • a surface 57 (FIG. 3) on the gluing device 20 in the region of the blunted corners 30A is made with a particularly strongly adhering material equips.
  • the adhesive applied there is more adhesive than the adhesive used on the other adhesive surfaces of the adhesive device 20, so that an immediate adhesive connection between the paper webs 14 and 16 takes place at the moment of pressing together by the pressure roller 26.
  • the adhesive used for surface 57 is manufactured, for example, by 3M; it is, for example, Scotch Brand product 913 Repulpable Newsprint Splicing Tape.
  • the adhesiveness of an adhesive in a conventional adhesive device begins to decrease as soon as the adhesive is exposed to the air. This may be due to the evaporation of solvents in the adhesive as soon as it is released into the air.
  • all adhesive surfaces are sealed with protective cover layers or covered with removable layers that are not removed before the adhesive device is prepared for the splice.
  • the adhesive surface 57 is covered by a protective layer 59, and the remaining portions of the adhesive device are also covered by five separate protective layers 58, 60, 62, 64 and 66. They each have a pretreated inner surface, which is treated, for example, with a silicone compound, so that the protective layers 58 to 60, 62, 64, 66 can be quickly removed from the adhesive surface, but protect it as long as it covers it.
  • the front edge of the adhesive pattern 20 is held in place on the surface of the new paper roll 16 by adhesive strips 40. During splicing, it is necessary that the front edge 36 of the adhesive pattern 20 can be torn off the outer surface of the paper web 16 as soon as the adhesive surface 57 abuts the paper web 14.
  • a reinforcing tape 68 (FIG. 4) is arranged on the rear side 29 of the adhesive device. The presence of the reinforcement tape 68 causes the adhesive to peel off along lines 68A and causes a rapid tear-off process in which only a small amount of pressure is applied to the paper web 14.
  • this adhesive device 20 can be reproduced in the same dimensions and with the same adhesive surfaces and that the dimensions of the adhesive device are always the same. Covering the adhesive surfaces ensures that the adhesive itself does not lose its adhesive properties. It follows that the adhesive device 20 can be produced in large quantities, that it can be stored well and can be applied to a roll of paper and can be left in this position while its adhesive surfaces are covered until the splicing is carried out so that almost 100% splicing security is created.
  • Fig. 5 shows another embodiment of the adhesive device according to the invention, which has only a single triangle.
  • the construction of this gluing device is the same as in FIG. 3, and the reference numerals are to be understood in the same way as in FIGS. 3 and 4.
  • This gluing device is used in the same way as the gluing device shown in FIG. 3.
