Abstract
A method and a device (10) for setting up a web (1) of paper having lateral dragging holes (2) in a paper processing and/or printing apparatus. The device (10) is capable of making a reference hole (3) at the midway line (4) between two successive lateral holes (2a,2b). According to the method, when the web (1) is dragged by a paper dragger (7), reference hole (3) passes under a sensor (6) which signals the passage of it to a control unit. The control unit stores such passage and starts the linear measurement of the web from that moment, by an encoder. The control unit operates a perforating apparatus (8) which makes on the web transversal perforations (9) at the chosen distance for one another. Transversal perforations 9 are made coinciding with the midway line of two successive lateral dragging holes.
