PACKET STACKING APPARATUS

摘要

An apparatus for stacking filled flat bags advanced thereto in at least one coherent row forming a bag web of indeterminate length, comprises an advancing arrangement for feeding the bag web vertically downwardly; an orienting arrangement for imparting a back-and-forth oscillating motion on the downwardly advancing bag web; a collecting arrangement situated below the orienting arrangement in the path of the bag web for receiving the bag web in zigzag-folded layers; and a synchronizing arrangement for coordinating the operational speed of the advancing arrangement with that of the orienting arrangement for determining the length of the zigzag-folded layers deposited on the collecting arrangement.
