  • the belt member 120 of the first outer circumferential member 114 is movable in the circumferential direction relative to the first rotating member 113 that rotates together with the cutting blade 111. Therefore, the speed of the cutting blade 111 and the speed of the belt member 120 can be made different at the point of contact with the web. For example, by making the speed of the belt member faster than the speed of the cutting blade, the web cutting interval can be made longer than the circumferential length of the cutter roll, and the speed of the belt member is made slower than the speed of the cutting blade. Thereby, the cutting interval of a web can be shortened rather than the circumferential direction length of a cutter roll. Therefore, it is possible to easily adjust the interval for cutting the web to cope with various sizes.

Abstract

Un dispositif de découpe (100) est pourvu d'un rouleau découpeur (110) et d'un rouleau enclume (130) qui est disposé de manière à faire face au rouleau découpeur. Le rouleau découpeur est pourvu : d'un premier organe rotatif (113) possédant une lame de découpe (111) et tournant dans la direction α ; d'un premier organe périphérique extérieur (114) tournant quand le premier organe rotatif tourne ; et d'un organe d'entraînement. Le premier organe périphérique extérieur (114) est pourvu : d'une première section de contact (120a) destinée à distribuer une bande (7) dans la direction d'acheminement (MD) ; et d'une première section à déplacement relatif (121) destinée à déplacer la première section de contact par rapport au premier organe rotatif (113). La première section à déplacement relatif (121) est configurée de manière à déplacer la première section de contact le long de la périphérie extérieure d'un premier arbre rotatif.
