Abstract: 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.

Abstract: A folding apparatus for a continuous web for production of absorbent hygiene articles and intended to be folded into a “V” or “U” shape in first and second longitudinal portions along a folding line parallel to a feeding line. A folding section includes a contact unit extending along the feeding line and defining the folding line. First and second guides are positioned on opposite sides of the contact unit and respectively have first and second sliding surfaces. The first and second sliding surfaces extend in a helical fashion along the feeding line, each having a respective infeed section, where the web is not folded, and a respective outfeed section, positioned downstream of the respective infeed section according to a web feeding direction, where the web is folded in two and has the first portion and the second portion set at an angle to each other.
