Schlauchbeutelmaschine mit einer Einrichtung zum Staubfreihalten der Innenseite eines Folienschlauches in dessen Siegelbereich

摘要

Between a filler pipe (22) and a moulding pipe (12), a bag forming, filling and sealing machine (10) has at least two seals (28) which separate an annular space (23) formed by the filler pipe (22) and the moulding pipe (12) into an input (31) and an extractor channel (32). The two channels (31, 32) are connected to a suction device (36) with a filter (37) via tubes (34, 35). The design and arrangement of the seals (28) provide a closed circuit for the air or protective gas used for dust removal.
