Flexible tube bagging machine

摘要

A flexible tube bagging machine having a feed device for a foil, a shaping member over which the foil is drawn and formed into a tube and a foil transfer device arranged downstream of the shaping member. The shaping member has a sleeve portion and a collar for engaging the foil. The collar is secured to the sleeve portion and guides the foil inside of the sleeve portion. The collar has a collar neck portion and two collar chest portions connected to the collar neck portion and face outwardly from a front side of the machine. The collar chest portions converge in a conveying direction of the foil and effect a guiding of the lateral edges of the foil toward one another. The collar chest portions are of different length and the longer collar chest portion extends through a central plane extending through the longitudinal axis of the sleeve portion to a position adjacent an opposed edge of the cutout and being perpendicular to the front side of the machine. The collar neck portion is asymmetrical with respect to the central plane and the part which lies on the side of the longer collar chest portion is wider than the other part thereof.
