  • Patent number: 10028863
    Abstract: A machine for making absorbent sanitary articles, where each article includes components progressively positioned relative to each other and assembled along a production line. The machine includes a programmable electronic controller device having a shift register, at least one optical inspection system connected to the programmable electronic controller device, and an operator interface connected to the electronic controller. The programmable electronic controller device generates a machine sync signal, a trigger signal for activating the optical inspection system in phase with the sync signal and a shift register shift command. The optical inspection system receives the trigger signal and has a defined maximum response time which produces at least one band of uncertainty. The operator sets with the operator interface the instant of activating the shift register shift command outside the band of uncertainty and between two consecutive sync signals defining a machine step.
