Title (EN) TAPE RESTRAINT FOR USE WITH WRAPPER SEALING ANVIL
(FR) BANDE DE RETENUE DESTINEE A UNE ENCLUME DE SCELLEMENT D'EMBALLAGES
Abstract:
(EN) In a machine for making heat seals in plastic materials an anvil (14) having a cushioned surface (24) is overlaid with a nonstick tape (26) to preclude the plastic materials being sealed from sticking to the anvil (14). The nonstick tape (26) is wrapped around the anvil (14) such that it is restrained on the bottom side as well as the sides of the anvil.
(FR) Dans une machine de thermosoudage de matériaux plastiques une enclume (14) possédant une surface tampon (24) est recouverte d'une bande non-adhésive (26) afin d'empêcher les matériaux plastiques de coller à l'enclume (14) durant le scellement. La bande non-adhésive (26) est enroulée autour de l'enclume (14) de telle sorte qu'elle soit retenue sur le dessous aussi bien que sur les côtés de l'enclume.
