Abstract

Selon la présente invention, une pâte à papier qui a été transportée vers une position déplacée à partir d'une position normale peut être superposée et stockée sur une pâte à papier précédemment stockée. Un dispositif de traitement de papier-monnaie (1) est équipé : d'une unité de stockage (5) permettant de former un espace de stockage (5a) dans lequel du papier-monnaie (M) est mis en couches et stocké ; d'un mécanisme de transport permettant de transporter du papier-monnaie (M) vers l'unité de stockage (5) ; et d'une pièce mobile (37) destinée à entrer dans l'espace de stockage (5a) et à sortir de celui-ci, la pièce mobile (37) étant disposée dans une direction orthogonale à la direction de transport du papier-monnaie (M) transporté au moyen du mécanisme de transport. Le transport est arrêté dans une position dans laquelle la partie d'extrémité arrière dans la direction de transport du papier-monnaie (M) à transporter vers l'unité de stockage (5) au moyen du mécanisme de transport fait face à la pièce mobile (37), la partie d'extrémité arrière du papier-monnaie (M) dans la direction de transport dans une position faisant face à la pièce mobile (37) étant ensuite déplacée vers le côté espace de stockage (5a) et le papier-monnaie (M) étant mis en couches et stocké dans l'espace de stockage (5a) au moyen de l'actionnement d'entrée et de sortie de la pièce mobile (37).
