ABSTRACT:
A device for re-reeling and forming a roll of paper in a re-reeling machine comprising, on a frame, three rollers (16, 17, 18) having mutually parallel axes that are perpendicular to the direction of feed of the paper (11), in which two winding rollers, a bottom one (17) and a top one (16), supported on the frame, co-operate with a third roller (18) that maintains a certain pressure on a roll of paper or log being formed, where the third roller (18) is carried by a pair of arms (22) which can oscillate with respect to the frame, the paper (11) that is being wound passing over one of the two rollers, and the finished roll or log (19) coming out of an outlet aperture or gap (30) identified between the bottom roller and the third roller, and the cores (12) for said rolls being fed, one after another, by a pusher conveyor (15) and being introduced into a channel (24) made underneath the top roller (16) by an oscillating pusher (27, 35) which co-operates for inserting the core (12), possibly provided with adhesive, there also being provided an arrest element (32, 132) for at least partial arrest of the paper (11) upstream of the point of insertion of the core (12).
