Title (EN) UNIT FOR TRANSFORMING A SUBSTRATE IN A CONTINUOUS BAND AND WRAPPING PRODUCTION MACHINE EQUIPPED WITH SAME
(FR) UNITE DE TRANSFORMATION D'UN SUPPORT EN BANDE CONTINUE ET MACHINE DE PRODUCTION D'EMBALLAGES AINSI EQUIPEE
Abstract:
(EN) A transformation unit transforming a first substrate in a continuous band (2) into a second substrate in the form of transformed pieces with a predetermined length (3), the band (2) having a constant entry speed, comprises a first motorized arrangement (4) for performing a first feed driving (F) of the band (2), a sheet cutter (12) with rotary tools (13, 14) for cutting the band into pieces (3), a second motorized arrangement (17) for performing a second feed driving of the substrate (2, 3), positioned in the immediate vicinity of the sheet cutter (12), and at least one station (21, 22, 23) with rotary tools (26, 27, 28, 29, 32, 33) to transform the pieces (3). A speed of rotation (38, 41) of the second arrangement (17) varies during a rotation cycle of the tools (13, 14) of the sheet cutter (12), having a constant tangential speed phase (46) substantially equal to the speed of rotation of the tools (13, 14) of the sheet cutter (12), during which the cutting is done, a speed decrease phase (43), during which a band length (2), depending on the difference between the length of the piece (3) and a development of the tools (26, 27, 28, 29, 32, 33), is kept upstream from the second arrangement (17), and a speed increase phase (44), during which the substrate (2, 3) is discharged downstream from the second arrangement (17).
(FR) Une unité de transformation transformant un premier support en bande continue (2) en un deuxième support sous forme de poses transformées à longueur prédéterminée (3), la bande (2) présentant une vitesse d'entrée constante, comprend un premier agencement motorisé (4) pour réaliser un premier entraînement en défilement (F) de la bande (2), un coupe-feuille (12) à outils rotatifs (13, 14) pour réaliser une coupe de la bande en poses (3), un deuxième agencement motorisé (17) pour réaliser un deuxième entraînement en défilement du support (2, 3), positionné à proximité immédiate du coupe-feuille (12), et au moins une station (21, 22, 23) à outils rotatifs (26, 27, 28, 29, 32, 33) pour réaliser une transformation des poses (3). Une vitesse de rotation (38, 41) du deuxième agencement (17) varie au cours d'un cycle de rotation des outils (13, 14) du coupe-feuille (12), en présentant une phase à vitesse tangentielle constante (46), sensiblement égale à la vitesse de rotation des outils (13, 14) du coupe-feuille (12), pendant laquelle la coupe est réalisée, une phase de diminution de la vitesse (43), pendant laquelle une longueur de bande (2), fonction de la différence entre la longueur de la pose (3) et un développé des outils (26, 27, 28, 29, 32, 33) est conservée en amont du deuxième agencement (17), et une phase d'augmentation de la vitesse (44), pendant laquelle le support (2, 3) est évacué en aval du deuxième agencement (17).
