Abstract

La présente invention concerne un dispositif de séparation de feuilles de papier (11) comprenant : un rouleau de séparation (16) qui vient en contact avec des feuilles de papier envoyées à partir d'une unité d'accumulation conçue pour accumuler des feuilles de papier ; un rouleau d'alimentation (17) qui est disposé de façon à être en contact avec le rouleau de séparation (16) et qui sépare et transporte des feuilles de papier une feuille à la fois par rotation par rapport au rouleau de séparation (16) arrêté ; et une paire d'éléments de guidage (18) qui ont des faces de guidage (18a) en contact coulissant avec le bord avant de feuilles de papier envoyées à partir de l'unité d'accumulation et qui sont disposées des deux côtés du rouleau de séparation (16) dans la direction axiale. Le coefficient de frottement des faces de guidage (18a) de la paire d'éléments de guidage (18) est inférieur au coefficient de frottement de la face circonférentielle (16a) du rouleau de séparation (16). Les faces de guidage (18a) font saillie vers l'extérieur du rouleau de séparation (16) plus loin que la face circonférentielle (16a) du rouleau de séparation (16) dans la direction radiale du rouleau de séparation (16), et les faces de guidage (18a), au niveau du point de contact entre le rouleau de séparation (16) et le rouleau d'alimentation (17), sont supportées de manière à pouvoir se déplacer vers l'intérieur du rouleau de séparation (16) dans la direction radiale.
