Abstract

La présente invention aborde le problème de la fourniture d'un dispositif d'alimentation en feuilles et d'un dispositif de fabrication de boîte doté d'un mécanisme d'alimentation en feuilles qui permettent une économie de main-d'œuvre. Un dispositif d'alimentation en feuilles (10) fournit des feuilles de fabrication de boîte (S) à un dispositif de fabrication de boîte (100) qui stocke une pluralité de feuilles de fabrication de boîte dans une unité de stockage (112) dans un état dressé de façon à croiser une direction horizontale et retire les feuilles de fabrication de boîte de l'unité de stockage pour fabriquer une boîte. Le dispositif d'alimentation en feuilles est pourvu d'une unité de montage (20) et d'une unité d'alimentation (60). L'unité de montage reçoit la pluralité de feuilles de fabrication de boîte dans un état posé depuis l'extérieur. L'unité d'alimentation change la pose de l'unité de montage à partir d'une première pose (P1) pour recevoir la pluralité de feuilles de fabrication de boîte depuis l'extérieur vers une seconde pose (P2) pour ainsi changer la pose de la pluralité de feuilles de fabrication de boîte de l'état posé à l'état dressé, puis fournit la pluralité de feuilles de fabrication de boîte dans la pose modifiée au dispositif de fabrication de boîte.
