Device for severing and simultaneously perforating printed strips of paper or the like

摘要

The invention relates to a device for severing and simultaneously perforating printed strips (2) of paper or the like using cutting or perforating knives (9, 11). In order to permit such a device to achieve simultaneous severing and perforating in a single operating cycle, provision has been made according to the invention for a rotatably mounted cutting roller (7) to be provided with a continuous slot (8) of a certain length (B), through which the strip (2) can be advanced, for the cutting knife (9) to be arranged on the strip inlet side of the slot (8) and for the perforating knife (11) to be arranged on the strip outlet side of the slot (8) so as to drag around the periphery of the cutting roller (7) in such a way that when the cutting roller (7) rotates a short distance, the strip (2) can be simultaneously severed and perforated at a distance from the cutting point (16) which corresponds to the length (B) of the slot. <IMAGE>
