Title: Device for separating/folding individual sheets and apparatus for manufacturing bags including such a separating/folding device
Inventor: HATCHELL PETER J
IPC: B65H35/10
Filed: 1992-05-13
Abstract: The bag machine includes a separating/folding device (28) and produces individual folded bags (22) made from plastic material. Two high-speed separation rollers actuated by a cam mechanism driven by a servomotor take a continuous strip (12) of plastic material in order to separate individual bags (22) made from plastic material which are formed in the strip. Two parallel wide strips and two similar superposed strips seize the two sides of the separated bags (22) and transport the bags towards several folding stations. A two-speed deceleration mechanism at the exit end of the separating/folding device (28) slows down the folded bags in order to facilitate downstream handling. An optional stacking and indexing transporter (conveyor) automatically stacks predetermined numbers of folded bags, aligns them and compresses them in order to form a stack.
