  • the webs that are turned out of the side of the machine are folded lengthways on the former and can be further processed in one of two folders arranged under the former structure.
  • a funnel construction for a triple-width printing press is known from DE 25 10 057 A1, which has three upper and three lower funnels arranged next to one another.
  • the funnels of the lower and upper levels are rotated relative to one another by 180 ° about their vertical longitudinal axis in such a way that the folded products have their backs on different sides.
  • DE 41 28797 C2 also discloses a funnel structure for a triple-width printing press, with six funnels being arranged on three levels in order to increase the variety of products.
  • EP 11 45 850 A1 shows a funnel structure of a printing press for illustration printing, wherein in addition to a four A4-page wide first funnel, a second funnel which is either correspondingly wide or part-wide and a third part-wide, smaller funnel is arranged.
  • the two outer funnels and thus also the strands produced by these funnels can be displaced in the longitudinal direction of the printing press in order to enable a staggered delivery of the products which are subsequently cut transversely.
  • DE 199 59 152 A1 discloses a divided web guide roller for guiding a double-wide web, the two roller sections being able to be driven independently of one another by means of their own drive motors for the simultaneous production of two different products having different supports.
  • DE 42 04254 C2 shows two funnels arranged in one plane, which are arranged to be horizontally movable.
  • a third funnel is arranged in a level above or below the center of an incoming entire web.

Abstract

L'invention concerne un dispositif de fabrication de produits repliés à partir de bandes (01,01') et/ou de bandes partielles (27,27'). Ce dispositif comprend un ensemble de pliage (02) équipé d'un groupe (37) d'au moins trois entonnoirs (O8,O9,26) agencés de façon décalée horizontalement les uns par rapport aux autres et dans un sens perpendiculaire à un sens d'avance de la bande. Chaque entonnoir (08,09,26) a au moins une largeur correspondant à deux pages de journal droites ou quatre pages d'impression couchées au format tabloïde. En sens horizontal, ces entonnoirs s'entrecoupent au moins partiellement dans leur sens vertical, au moins un des entonnoirs extérieurs (26,08) du groupe étant toutefois décalé, par rapport à un entonnoir intérieur (09), d'une certaine hauteur (41) en sens vertical.
