Abstract
A punching and/or perforation equipment () for continuous paper forms () comprising punching and/or perforation member () and contrast elements () substantially tangent to the movement surface () of the forms and a punching and/or perforation mechanism () for driving the punching and/or perforation members. A detecting device () detects at least one reference position the forms associated with the punching and/or perforation positions and a servomechanism () 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 (). 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 ().
