Abstract

Continuous form paper for use in computer output printers has a marginal area which includes the feed holes for moving the paper through the printer. In some systems, an output station is included in which the continuous form is burst into sheets and the marginal edge is trimmed from the sheet. The paper trimmed from the marginal edge assumes a random orientation and produces a relatively large bulk, which may create a disposal problem. A cutter 10 is provided in line with the edge trimmer to cut the edge trimmed paper 12 into relatively short pieces, to reduce the bulk space to a small fraction of the original volume. The cutter 10 comprises fluted spiral cutters 16 and a fixed pin 14 mounted adjacent to the cutter.

Paper Cutter

Continuous form paper for use in computer output printers has a marginal area which includes the feed holes for moving the paper through the printer. In some systems, an output station is included in which the continuous form is burst into sheets and the marginal edge is trimmed from the sheet. The paper trimmed from the marginal edge assumes a random orientation and produces a relatively large bulk, which may create a disposal problem. A cutter 10 is provided in line with the edge trimmer to cut the edge trimmed paper 12 into relatively short pieces, to reduce the bulk space to a small fraction of the original volume. The cutter 10 comprises fluted spiral cutters 16 and a fixed pin 14 mounted adjacent to the cutter. The rotational speed of the cutter 10 is directly proportional to the feed rate of the paper and when one of the spiral cutters 16 is adjacent the pin 14, the trimmed paper is cut, thereby reducing the bulk of the trimmings.
