Patent ID: 8353236

Claim:
A perforating equipment for continuous forms in movement comprising a first transversal perforating device and a second transversal perforating device for executing transversal perforations on requested positions of the form, wherein said equipment is provided for perforating continuous forms to be divided in three longitudinal sections and comprises a third transversal perforating device similar to the first perforating device, wherein each transversal perforating device includes a contrast member with a contrast surface having possibility of tangency with the movement surface of the form and in synchronism with the form, a blade support provided for rotation and mounting at least a perforating blade, said blade having possibility of interference with the form in movement for executing transversal perforations; a blade servomechanism servoized to indications of position of the form and controlling the rotation of the blade support for a condition of interference of the blade or a selected blade in the requested position of the form; and an activation group for positioning the contrast surface against the blade or a selected blade in transit; wherein the blade supports of the first perforating device and the second perforating device each mount two blades of which a blade for two section forms is associated to the perforation of continuous forms to be divided in two longitudinal sections and a blade for three section forms is associated to the perforation of continuous forms to be divided in three longitudinal sections; and wherein a controller having at least two modes, in a first mode the activation group of the first and second perforating devices causes the blades for two section forms to engage a respective contrast surface, and in a second mode the activation group of the first and second perforating devices causes the blades for three section forms to engage a respective contrast surface.
