CA 2211912

The invention relates to a method and an apparatus (1) for erecting flat-laid packaging container blanks (3). The packaging container blanks (3) are fed one-by-one from a magazine (4) into the apparatus (1) where they are forced into a gap between an erector roller (14) and a counter pressure roller (22). On the axial surface (15) of the erector roller (14), there are disposed anumber of suction cups (16) which are activated when the packaging container blank (3) reaches the erector roller (14) so that a panel (8) of the packaging container blank is fixedly retained against the surface (15) of the erector roller (14). When that panel (7) ahead of the fixedly retained panel (8)is free, a corner (10) of the packaging container blank (3) will be opened because of the bending against the erector roller (14). The opened corner (10) is further opened against a carrier (24) on a carrier chain (23) and the packaging container blank (3) is erected and enclosed in the carrier (24).

Méthode et appareil (1) pour monter des découpes empilées à plat de contenant d'emballage (3). Les découpes (3) alimentent l'appareil (1) une à la fois à partir d'un chargeur (4) où elles sont forcées dans un écart entre un rouleau monteur (14) et un rouleau de contre-pression (22). Sur la surface axiale (15) du rouleau monteur (14), il y a plusieurs ventouses (16) qui sont activées lorsque la découpe (3) atteint le rouleau monteur (14) de façon à retenir fermement un des panneaux (8) de la découpe sur la surface (15) du rouleau monteur (14). Lorsque le panneau (7) situé avant le panneau retenu (8) est libéré, un des coins (10) de la découpe (3) s'ouvrira à cause de la courbure contre le rouleau monteur (14). Le coin ouvert (10) s'écarte encore plus contre un transporteur (24) sur une chaîne de transport (23) et la découpe de contenant d'emballage (3) est montée et enfermée dans le transporteur (24).
