Valved sack extraction mechanism from magazine - has end portion sucked out before mechanically gripping for further extraction

摘要

The mechanism extracts a valved sack from a magazine and prepares it for fitting over a filling machine spout. The foremost sack is sucked out of the magazine and turned into the filling position. Only an end portion of the sack (2) is sucked out of the magazine (1), after which this portion is mechanically gripped and extracted in the lengthwise direction of the sack. It is then turned through roughly 180 deg., and supported on its rear side in the final position. Suction is then applied to its front for further preparation.
