  • the driving of said means should be anticipated in case of high dragging speeds of the paper material, and retarded in case of lower dragging speeds.
  • control unit also determines the instant of deactivation for the electromagnet of the related actuator. This instant can be computed by the control unit taking into account, as already for the instant of driving, both the instantaneous velocity of the paper material and the removal times associated to the actuator and to the type of return means employed.
  • the apparatus of the invention is extremely versatile, enabling a selective perforation of the documents, and thereby enabling to manufacture different documents, and in particular with different perforation requirements, in a continuous operating cycle.
