Abstract
A punching and/or perforation equipment (33, 34) for continuous paper forms (37, 42) comprising punching and/or perforation member (81; 226, 227) and contrast elements (82; 224) substantially tangent to the movement surface (63, 204) of the forms and a punching and/or perforation mechanism (56, 57; 197, 198) for driving the punching and/or perforation members. A detecting device (92, 93; 244, 245) detects at least one reference position the forms associated with the punching and/or perforation positions and a servomechanism (87, 88; 228, 229) actuates the punching and/or perforation mechanism on the basis of the reference position or positions between a state of rest and a state of punching and/or perforation and in which the reference position or positions are associated with information of a position encoder (72, 214). The punching and/or the perforation members cooperate with the form with a peripheral velocity, at the moment of the punching and/or perforation, substantially equal to the velocity of the moving form (37, 42).
