Abstract

L'invention concerne un dispositif permettant de produire un article cousu, de surface étendue, comprenant un organe de couture à aiguilles multiples (1), un dispositif d'approvisionnement en couches d'articles à coudre, monté en amont de l'organe de couture à aiguilles multiples et un poste de traitement (3), monté en aval du dispositif d'approvisionnement en couches d'articles à coudre (1) et prévu pour l'article cousu (4). L'organe de couture à aiguilles multiples (1) présente une pluralité d'organes de couture et un dispositif de guidage (11) pour l'article à coudre (4). Ledit dispositif de guidage (11) est monté dans la zone des organes de couture et peut être déplacé par rapport aux organes de couture, dans une direction sensiblement perpendiculaire au sens d'acheminement de l'article à coudre (4). L'invention vise à perfectionner un dispositif et un procédé de ce type de générique, de sorte que l'article cousu fini parvienne dans le poste de traitement ou au moment de la couture, entre les organes de couture, à l'encontre du sens d'acheminement, essentiellement sans ou du moins avec très peu d'écart par rapport au sens d'acheminement. A cet effet, il est prévu de disposer entre l'organe de couture à aiguilles multiples (1) et le poste de traitement (3), un dispositif (22) pour compenser un déport angulaire de l'article cousu (4) entre une sortie du dispositif de guidage (11) et une entrée (24) du poste de traitement (3).
