MECHANISM FOR STACKING AND ACCUMULATING STACKS OF FLAT FLEXIBLE ARTICLES

摘要

MECHANISM FOR STACKING AND ACCUMULATING STACKS OF FLAT FLEXIBLE ARTICLES A mechanism for stacking and accumulating a plurality of stacks of predetermined numbers of flat flexible articles, such as pillowcases and like products, sequen received therein, such as from a machine fabricating such articles. A plurality of bar holders sequentially receive the articles in draped-over superimposed position at an entrance end of the mechanism to form separate stacks and are selectively conveyed longitudinally through the mechanism (1) from the entrance end through a stacking section to an accumulating section, (2) incrementally through the accumulating section to an exit end of the mechanism in a plurality of incremental longitudinal distances each of which is less than the longitudinal distance through the stacking section, and (3) back to the entrance end.
