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.

Abstract: An apparatus for forming an absorbent pad for an absorbent sanitary article having a zone free of absorbent material to define a channel of the pad includes a forming drum, a first feed system for feeding a first web, a second feed system for feeding a second web, a spreader for spreading the absorbent material on the drum; a joining system for joining the first and second webs to define the channels. A first dispenser forms on the first web a layer of first adhesive substance according to a spreading pattern having zones free of the first adhesive substance corresponding to the channels. A second dispenser dispenses a second adhesive substance, whose adhesive force is greater than an adhesive force of the first adhesive substance, on the second web according to a pattern having a layer placed at a zone free of the first adhesive substance.

Abstract: A rotary device for welding a continuous web comprises a rotary unit rotating about a respective axis and welding units for welding the web mounted, angularly spaced, on the rotary unit. A movement device varies a radial position of the welding units. First and second supporting elements supporting the web are disposed, respectively, upstream and downstream of respective ones of the welding units, to keep the web tensioned when the respective welding unit is at an operating position. The first and second supporting elements are supported by a load-bearing structure connected to the welding units in such a way that a radial movement of the welding units corresponds to a movement of the first and second supporting elements towards and away from the axis.
