Definitions

  • the present invention relates to a perforating net or the like usable in particular on printing machines such as offset machines, as well as its method of implementation on said machines.
  • the perforating nets currently used on printing machines consist of a generally metallic strip having a toothed or sharpened lateral edge, which has on its face opposite the toothing, a layer of adhesive material on which is arranged a protective tape which is removed at the time of use.
  • a perforating net of this type in which the layer of adhesive material consists of a double-sided adhesive is described in particular in patent FR.A. 1512643.
  • perforating nets are intended to be stuck on a pressure cylinder of the printing machine and more particularly in the case of an offset on the margining cylinder compressing the sheets to be printed on the blanket cylinder.
  • the object of the invention is to eliminate all of these drawbacks.
  • a perforating net comprising, in a known manner, a rigid core which may be in the form of a metal strip, preferably made of steel and which has, projecting, on one of its two faces, at least one element possibly cutting or perforating, one of the sides of the core carrying a double-sided adhesive.
  • This perforating mesh is more particularly characterized in that a layer of adhesive material is placed on the side of the core opposite the perforating element and in that the double-sided tape-like adhesive is placed on the side of the core adjacent to the above element.
  • the above layer of adhesive material and the above adhesive tape are protected by a respective protective strip, to be removed at the time of use.
  • the above-mentioned element consists of a toothed or sharpened edge, which extends perpendicular to the plane of said strip.
  • the perforating thread 1 comprises a core in the form of a steel strip 2 comprising a flange 3 at right angles to the upper part of which are sharp teeth 4 of so as to make a serrated perforation edge.
  • the lower side of the strip 2, opposite the serrated edge, is coated with a layer of adhesive material 5 covered with a protective strip 6 which can be removed for the purpose of use of the perforating net 1.
  • the upper side of the strip 2, adjacent to the serrated edge is covered with a double-sided adhesive strip, that is to say a strip 7 carrying on its two faces an adhesive coating 8, 9, the adhesive coating 8, located on the side opposite to the steel strip 2, being protected by a protective strip 10 which can be removed when using the perforating net 1.
  • Such a machine conventionally comprises a plate cylinder 12 provided with ink rollers 13 and wetting rollers 14, a blanket cylinder 15 and a pressure cylinder or margining cylinder 17.
  • the blank sheets to be printed are stacked in a feed station 18 and are transmitted one by one in a margining area 19 before passing between the blanket cylinder 15 and the margining cylinder 17 where the printing takes place.
  • the sheets thus printed are then stacked in a receiving station 20.
  • the operator removes the protective tape 6 covering the adhesive layer 5 of the perforating nets 1 and then passes the sheet thus equipped (sheet 22) through the machine, nets perforators 1 located on the side of the margining cylinder 17.
  • the perforating threads 1 automatically stick to the margining cylinder 17 (threads in broken lines 23).
  • the double-sided adhesive tape 7,8,9. which remains stuck on the sheet, detaches from the perforating nets 1 (the adhesion of the double-sided adhesive tape 7, 8, 9 on the paper being stronger than its adhesion to the perforating net 1).
  • the perforating nets 1 are placed on the margining cylinder 17 at the suitable locations. The operator can therefore perform his printing operations with perforation.
  • the invention is not limited to the type of perforating thread shown in Figures 1 and 2. It also relates to all threads of this kind such as grooving threads and cutting threads.
