reprographic composite sheet material separator - pulls cover sheet backwards over an acute angle edge away from main support sheet

摘要

The composite material has a photo sensitive layer in thermoplastic, interleaved between a cover sheet and a support sheet of material. Both sheets are allowed to adhere to the photosensitive sheet by the same method. The material is separated by pulling the material backwards to an acute angle (3). The main roll of material (17) passes over guide rollers (18) and between the drive rollers (6) and (7). The composite sheet is pulled apart at the angle (3) where the material is doubled back along itself and over guide rollers (18). The material is then wound onto the drum (19).
