A MACHINE FOR FOLDING FLEXIBLE SHEET MATERIAL

摘要

A machine for folding bags wherein bags are rolled and removed from rolling cages (28, 30) through an opening (32) between the rolling cages. The rolling cages have an internal moving surface extending through an arc of 270 DEG formed by a series of drive rollers (26) mounted on shafts (20). …In order to minimize ballooning of the bag during rolling the moving surface within the rolling cages (28, 30) is extended beyond the rolling cages and into the opening between the rolling cages.
