A perforating equipment (111) for continuous forms in movement comprises tree transversal perforating device (54, 56, 57) for executing transversal perforations on continuous forms (58) to be divided in three longitudinal sections and continuous forms to be divided in two longitudinal sections. Each perforating device includes a contrast member (61, 62, 79), a blade support mounting a blade (116a, 117a, 118a) for the three section form and a blade (116b, 117b, 118b) for the two section form, a blade servomechanism (73, 74, 85) and an activation group (104, 106, 107). The blade servomechanism rotates the blade support for a condition of interference of a blade in the position of perforation; and the activation group causes the contrast member to contrast a corresponding blade for the perforations of the forms to be divided into three sections, or the forms to be divided into two longitudinal sections.
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 perforating equipment for continuous forms in movement comprising a perforating device including a contrast member, an indented perforating blade mounted on a blade support provided for rotation in condition of interference with the form against the contrast member for the execution of transversal perforations and a blade servomechanism, servoized to indications of position of the form, for rotating the support blade in synchronism with the form and perforation in a requested position, wherein said device further comprises
A perforating equipment for continuous forms in movement comprising a given perforating device including a contrast member, more indented perforating blades mounted on a blade support provided for rotation in condition of interference with the form against a contrast surface of the contrast member for the execution of transversal perforations, and a blade servomechanism, servoized to indications of position of the form, for rotating the support blade in synchronism with the form and perforation in a requested position, said device further comprises
A perforating equipment for continuous forms in movement comprising a perforating device including a perforating device for continuous forms in movement comprising a contrast roller, substantially tangent to the movement surface of the form and synchronous with the feeding, an indented perforating blade, carried by a blade support and provided for rotation in condition of interference with the form against the roller for the execution of transversal perforations, and a servomechanism, servoized to indications of position of the form, for rotating the support blade in synchronism with the form and perforation in a requested position, said device further comprises a reciprocal shifting mechanism between blade support and contrast roller, actuatable for modifying the distance between the axes of the contrast rollers and the blade support between a condition of perforation, of engagement of the indented blade and an inoperative condition of disengagement of the blade;
