摘要： A rotary device for welding a continuous web includes a rotary element, support elements for supporting the web, supported by the rotary element, and a plurality of welding units for welding the web. Each welding unit passes from a non-operating position to an operating position and vice versa, and includes a first movement device for commanding a relative rotation of an anvil element relative to a welding tip and a second movement device for moving the anvil element relative to the welding tip such that a contact surface of the anvil element and a contact surface of the welding tip make contact with a portion of the web in a zone between them, and vice versa. First and second drive mechanisms drive the first and second movement devices. The first and second drive mechanisms are configured to vary a positioning of the welding tip relative to the axis.

摘要： A feeding unit to feed a component in an automatic manufacturing machine, which has at least one holding head designed to receive and hold the component; a conveyor to cyclically move the holding head along an application path; and a rotation station arranged along the feeding path and in which the holding head rotates relative to the equipment and around a rotation axis to vary the orientation of the component. The conveyor has a closed curve guide arranged in a fixed position along the application path; and an equipment supporting the holding head and provided with at least one slide coupled to the guide so as to freely slide along the guide. An actuation system controls rotation of the holding head around the first rotation axis and has a cam and a cam follower roller, which can be coupled to the cam and mechanically connected to the holding head.

摘要： 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.
