Dichtungssystem zum Abschliessen geschnittener Teile eines Materialstapels und Verfahren zum Abschliessen dieser Teile

摘要

An automated cutter bed (10) employs a sealer (44) which is mechanically coupled to a tool carriage and moves with it along a first coordinate direction. A first roller (46) is connected with a second roller (50) disposed at the take-off end of the table by an air impermeable sheet (52) which is tensioned between the two rollers by a resilient member (106) housed within each of the rollers causing a preload to be exerted on the air impermeable sheet material. The first roller moves between ends of the table paying out a length of the air impermeable material. As the carriage moves to the cutter datum, equalization is effected by the preloads given in each of the first and second rollers.
