Definitions

  • the invention is in the field of further processing of printed products and relates to a method and a device according to the preamble of the corresponding, independent patent claims.
  • the method according to the invention and the device for carrying out the method are used for adhesive binding, that is to say for connecting a plurality of partial products stacked on top of one another in the area of a stacking surface for the production of finished products with a glued back, a partial product consisting of a single sheet, of a single or multiple fold Arch or can consist of several nested, simply folded sheets.
  • the products consist of a fibrous material, such as paper.
  • the products produced by the perfect binding are, for example, magazines, brochures, books or the like.
  • the adhesive back can also be covered with a backing strip, which can be part of the cover sheets of the finished product.
  • adhesive backs for products consisting of multi-layered partial products are produced by milling the back surface formed by the folded edges of the multi-layered partial products to such a depth that all folded edges (possibly without the innermost folded edge) are removed and thereby actually a stack of unfolded single sheets arises, which is then glued like one.
  • the back surface is usually still dusted off between milling and gluing.
  • the method according to the invention is based on treating the edges of the partial products stacked on top of one another to be joined by gluing with a tearing or roughening tool (in contrast to a cutting tool) in such a way that multilayer folded edges are torn open completely at least in some areas.
  • the tearing or roughening creates edge areas to be glued, which consist of fibers that only partially adhere to the bond of the paper and protrude beyond the effective paper edge. These fibers not only anchor the sheets to be glued well in the adhesive on the back of the glue, they also represent a glued area that is thinner and more flexible than the entire paper layer, which means that the finished glued product can be opened more easily.
  • the properties of the treated edges to be glued can be advantageously influenced by appropriate selection of the tearing or roughening tool and by appropriate arrangement of the relative movement between the tearing tool and the edges to be treated, in that the fibers of the edge area after treatment with the tearing tool are as possible protrude completely and as orderly as possible over the paper edge.
  • FIG. 1 schematically shows the method according to the invention on the basis of a representation of successive stages of an emerging product with adhesive back, which is produced from a plurality of multi-sided partial products, each consisting of three sheets folded into one another.
  • the figure can also be understood as a schematic snapshot of a continuous process in which a multiplicity of products being produced are continuously guided past various processing tools in the conveying direction F and are pretreated on a back surface, provided with adhesive and a backing strip and pressed.
  • a stack 1 of, for example, four folded partial products is introduced, held by suitable holding means 3, the stacked partial products being arranged with folding edges lying against one another and the folding edges forming a back surface 2 to be processed into an adhesive back.
  • the stack 1 of partial products is conveyed past a tearing or roughening tool 4, which is a rotating brush, for example, the tearing tool 4 being arranged in such a way that its effect has a depth that is at least up to the innermost Position of the folded edges extends.
  • the edges arranged on the back surface 2 are torn open if they are folded edges, or they are converted from cut edges into torn edges if they are not folded edges.
  • the rotating tool is advantageously driven (arrow R) in such a way that it runs in synchronism with the conveying direction F of the product being produced.
  • the fibers of the torn edge regions are combed out of the edge regions by this direction of rotation, which further enhances the advantageous effect (see also FIGS. 2 and 3 and the associated description).
  • Fibers removed from the back surface by tearing and combing are suctioned off with suitable means 5 and / or mechanically removed from the tool 4.
  • the pretreatment with the tearing tool creates a stack of partial products with torn ones from the stack 1 of folded partial products Edges, for example a stack of single sheets with torn edges, which form the pretreated back surface 2 of the part product stack.
  • An adhesive 8 is applied to this pretreated back surface 2 with a suitable center in 7, by means of which the torn edges are connected to one another to form a beloved back optionally a back strip 9 is applied and pressed with a suitable pressing means 10 (arrow P). Heat may also have to be supplied for the curing or drying of the adhesive 8.
  • Variants of the back strip 9 shown in FIG. 1 are cover sheets or pairs of cover sheets which extend over the back. Covering the glued back with a back strip is a measure to improve the aesthetic impression of the finished product. This measure can of course also be omitted in such a way that the glued back on the finished product is visible as such.
  • the method according to the invention can be used not only for connecting a plurality of partial products but also for connecting the individual layers of a single multi-layer partial product, the method according to the invention taking on the function of stapling.
  • the method according to the invention is characterized by the pretreatment of the back surface 2 of the stack of partial products, while the other steps for creating the adhesive back are known per se. It turns out that after the pretreatment with the tearing or roughening tool, no further pretreatment steps are necessary, that is, directly after the tearing or roughening pretreatment, the adhesive can be applied.
  • the end product of the process is a multi-page printed product 12.
  • FIG. 2 shows, on a significantly larger scale, a sheet 20 of paper or of another fiber-containing material in the region of a torn edge 21, which is surmounted by fibers 22 combed over the edge, while the fibers in sheet 20 themselves are essentially undirected .
  • FIG. 3 schematically shows in cross section to the main surfaces of the sheets a plurality of sheets 20 which are held together by an adhesive back 23.
  • This figure clearly shows how the adhesive 8 essentially holds the tapered edge regions of the sheets 20 together. Because of the tapering of the edge areas, these are also more flexible than cut, that is, non-tapering edge areas, and thus make it easier to open the bound product. However, because of the orientation of the fibers (see FIG. 2) in the edge areas bound in the adhesive back, the mechanical strength is not significantly reduced, so that tearing of a sheet from the adhesive back is not promoted.
  • FIGS. 4a to 4c show various exemplary back surfaces 2a to 2c as can be produced by the method according to the invention.
  • the back surfaces 2a to 2c have a width d and a height h, the edges of the partial products running parallel to the height h.
  • the back surface 2a according to FIG. 4a has a pattern of bound areas 40 alternating with unbound areas 41.
  • the bound areas extend across the entire back width and over part of the back height. In these areas, the part product edges are pretreated and glued with adhesive.
  • the unbound areas 41 the edges of the partial products are unchanged, that is to say if the edges are folded, the folded parts are still connected to one another in these areas, which contributes significantly to the stability of the bound product.
  • the back surface 2b according to FIG. 4b shows more and narrower bound areas 40, but does not differ in principle from the back surface 2a according to FIG. 4a.
  • Figure 4c also shows a back surface 2c with narrow bound areas 40, which do not run parallel to the back width d, but obliquely to it. It can be seen that adhesive backs according to FIG. 4c are advantageously flexible and can be produced with a minimum of adhesive. Variants with intersecting, obliquely bound areas are also conceivable.
  • FIG. 5 shows, limited to the most essential, an exemplary embodiment of a device for carrying out the method according to the invention.
  • This device has a tearing tool in the form of a rotating brush 50, the axial extent of which is substantially the same as or greater than the back height of the stack 1 of partial products conveyed past it with the corresponding conveying means (not shown) in the conveying direction F.
  • the brush 50 is arranged in such a way that its axis A is aligned essentially parallel to the back surfaces 2 to be treated and that the distance between the back surfaces 2 of the incoming products 1 and the brush axis A is smaller than the brush radius, essentially by that Depth of the folded edges (see Figure 1).
  • the direction of rotation R of the brush 50 is advantageously set up in such a way that the brush is operated in synchronism with the conveying direction F; it is also possible to operate in the opposite direction.
  • the brush 50 is advantageously a wire brush.
  • the illustration according to FIG. 5 relates to the pretreatment of stacks 1 of partial products which are conveyed in a high-performance conveying stream, that is to say with main surfaces oriented transversely to the conveying direction F.
  • the brush For pretreatment of products that are conveyed with main surfaces and back heights aligned parallel to the conveying direction, the brush must be aligned perpendicular to the heights of the back surfaces conveyed past. In any case, the axis of the rotating brush must therefore be arranged essentially transversely to the conveying direction.
  • FIG. 6 shows a bird's eye view of a device with three coaxially arranged, rotating busts 51, on which the back surfaces 2 of stacks 1 of partial products conveyed in the conveying direction F are conveyed past and pretreated in three areas 40.
  • FIG. 7 also shows a bird's eye view of a device for producing adhesive backs according to FIG. 4c.
  • a plurality of disk-shaped tools 70 are provided, for example toothed disks, which are arranged coaxially or with parallel axes A, the conveying direction F being perpendicular to the tool axis A and the heights of the back surfaces 2 being oriented obliquely to the disks 70 are.
  • FIGS. 5, 6 and 7 show, in a very simplified manner, devices such as are used for the pretreatment of stacks 1 of partial products conveyed in a high-performance conveying flow (conveying direction F), in which, therefore, back surfaces 2 conveyed past them are treated with an essentially stationary tool will.
  • continuously conveyed products are analog Way pretreatable. Arrangements are also conceivable in which essentially stationary products are treated with moving tools, or arrangements in which both tool and products execute translatory movements, a relative movement between products and tool being produced.
