Abstract

L'invention concerne un système pour former une boucle de bande ainsi qu'un procédé et un dispositif pour la fabrication de couvercles à arracher. Une boucle (7) de bande de film est formée pendant le défilement d'une bande de film (6) se déroulant d'une bobine de réserve (2) et acheminée progressivement par un dispositif d'alimentation (4). Afin que cela puisse être réalisé sans dysfonctionnement à des cadences élevées, un système (1) est prévu, dans lequel un cylindre creux (10) repose sur la bande de manière lâche avec une liberté de mouvement limitée pour former la boucle de bande. Un tel système est prévu de préférence pour la fabrication de couvercles à arracher, dans le cadre de laquelle une bande de film est déroulée d'une bobine de réserve et est acheminée vers un poste de découpe et de scellement.
