  • the back side of stacked printed products is pulled over the sliding surface provided with the slot nozzle so that the adhesive emerging from the outlet slot can penetrate into the back zone of the stack in a well-dosed manner and unilaterally connect the printed products.
  • a glue pot for an edge banding machine comprises a glue head, the interior of which opens to the outside via an exit slot bounded by longitudinal side walls, and an applicator roll arranged outside the glue head in front of the exit slot, wherein a rotatable metering rod is arranged between the applicator roller and the longitudinal side walls of the exit slot.
  • Adhesives and their properties are for example in [5], Dubbel, paperback for mechanical engineering, 17th edition, Springer Verlag, Berlin 1990, pages G23 and G24 or in [5], Frank Kreith, CRC Handbook of Mechanical Engineering, CRC Press, Boca Raton 1998, chapter 12.3, pages 12-34 to 12-43 described.
  • the aesthetic properties of the adhesives are also important in the applications described above.
  • the adhesives have been made available in the desired colors to suppress or specifically bring about color contrast to adjacent objects.
  • the present invention is therefore based on the object to provide an improved adhesive application station, by means of which the problems described are avoided.
  • the adhesive application station which is intended in particular for binding stacked products, for use in edge banding machines, or for the assembly of elements in vehicle construction, comprises an adhesive dispensing head element having an adhesive chamber with an exit opening through which the adhesive extends the adhesive chamber can escape.
  • the adhesive chamber is provided with at least one inlet channel serving to supply a dye, through which the dye can be introduced into the adhesive chamber and mixed with the adhesive can emerge from the outlet opening.
  • the inventive adhesive application station allows the processing of adhesives according to conventional methods and, if dyes are used, with minimal additional effort.
  • the storage and use of adhesives of different colors is eliminated.

It is also possible to apply to an applicator roll, by means of which the adhesive is delivered to the objects to be processed. If the invention can be used with double-roll systems in which the adhesive is introduced into the nip through which products or product parts to be processed, for example layers of a laminate to be bonded, optionally textile layers, are guided.
  • the supply of the adhesive and its promotion within the adhesive chamber can be done in a conventional manner, for example by means of local or external printing units.
  • volumetric systems are used in which metered volumes of colorants and adhesives are supplied. That is, a volume X of an adhesive is added with a volume Y of a dye.
  • adhesives used so far such as cold adhesives, two- or Multi-component adhesives, hot-melt adhesive eg in the temperature range 40 ° C-100 ° C or hot melt adhesive in the temperature range 100 ° C-250 ° C can be used. It is particularly advantageous to use hot-melt systems by means of which thermoplastic adhesives are liquefied.
  • the dyes are chosen to match the adhesives, for example, made on the same basis.
  • a mixed product or laminate can be surface-coated, e.g. be discharged from a slot nozzle.
  • a mixed product or laminate can be surface-coated, e.g. be discharged from a slot nozzle.
