ABSTRACT:
A bag detection apparatus (50) for sensing the position and seam integrity of a deformable bag (24) and bag transfer apparatus (53) for gripping and maintaining positive control of the edges (25) of the bag (24) during transfer from a bag filling station to a bag closure station. The bag positioning and seam integrity detecting apparatus (50) includes pneumatic conduits (60-67) mounted on the bag distending assembly (23) of a bag filling apparatus (20) and coupled to pressure switches (68). A controller (101), monitoring increases in pressure at each pressure switch (68), determines the position and condition of the mounted bag (24). The transfer apparatus (52) includes a pair of elongated arms (80) having hook-shaped gripping fingers (82) formed to engage and cooperate with clamping members (83) to grip the bag proximate the upper edge (25). A bag detection method also is provided.
