ABSTRACT:
Apparatus for automatically inserting plastic liners in open-mouth multiwall paper bags having means for holding a stack of the bags to be lined, and means for opening the uppermost bag of the stack for insertion of a liner therein. Insertion is via an inserter having vacuum means for gripping a liner, the inserter moving forward into the opened bag at the top of the stack for inserting a liner grasped by the inserter into the bag. The inserter moves the lined bag forward to an outfeed position where an outfeed means engages the lined bag to feed it forward for being stacked and, with the grip on the liner released, the inserter is retracted for the next cycle of operation. Liners are supplied from a roll in which they are interconnected end-to-end in series at transverse lines of weakness, the leading liner of the series being torn off and fed into position for being gripped by the vacuum means of the inserter.
