Abstract (en)
[origin: EP0941928A1] The machine is designed to advance a tube (20) e.g. of thermoplastic film over a filling neck (110) to form the walls (38, 40) of a bag, cutting the tube transversely into sections, and fitting the cut end of the tube which is still held by the filling neck with a closure (50) made from interlocking transverse strips (51, 52). After the walls of the bag have been pressed together above the closure the bag is filled through the neck and its bottom edge is sealed when the next cut is made.
