Abstract

Copy control strips (1) are used to control the stacking of copy sheets (2) fed into a catch tray (3) from a photocopying machine (4). The strips (1) are made from Mylar and are of a defined thickness, width and length. Attached is a curved section (5) of medium to high density polyethylene or polypropylene which provides the cruved finger shape. The weight of the curved section and strip size are critical to performance and are subject to selection by test and analysis when the handling of several weights and sizes of paper are considered.

Copy control strips (1) are used to control the stacking of copy sheets (2) fed into a catch tray (3) from a photocopying machine (4). The strips (1) are made from Mylar and are of a defined thickness, width and length. Attached is a curved section (5) of medium to high density polyethylene or polypropylene which provides the cruved finger shape. The weight of the curved section and strip size are critical to performance and are subject to selection by test and analysis when the handling of several weights and sizes of paper are considered.

The curved fingers ensure contact of the curved high copy stack by the finger ends only. This is vital to prevent paper drag against the strip body which results in hangups and backup jams. The number of copies which can be handled satisfactorily is greatly increased over previous hold down devices. The flexible curved strip remembers its shape and recovers if accidentally deformed, and the finger shape allows paper control and low friction contact during tray movement in the case of an offsetting catch tray.
