ABSTRACT:
Transversal perforating apparatus of paper for printers fed by a continuous strip of paper (1) without lateral dragging holes. The apparatus (12) includes a perforator roller (13) holding a blade (16) substantially transverse to and engaging a pressure roller (14) rotating in synchronism with the perforator roller (13). The speed of the perforator roller (13) is varied and the position of the blade (16) is measured with respect to the paper. Encoders communicate with a central processor. Transverse perforations are made coincident with the beginning and the end of each page printed by printing heads (2,3). Intervals between two successive perforations can be varied during the course of printing.
