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).
A device for re-reeling and forming a roll of paper in a re-reeling machine comprising three rollers (16, 17, 18) having mutually parallel axes that are perpendicular to the direction of feed of paper (11), wherein said three rollers are supported on a frame, wherein two of said rollers are winding rollers, a bottom winding roller (17) and a top winding roller (16), which co-operate with a third roller (18) that maintains a certain pressure on said roll of paper or log, wherein said third roller (18) is supported by a pair of arms (22) which oscillate with respect to said frame, wherein said paper (11) passes over said top winding roller (16), and a finished roll or log (19) comes out of an outlet aperture or gap (30) located between said bottom winding roller and said third roller, wherein cores (12) for said rolls of paper which are fed one after another by a pusher (15) of conveyor (13) are introduced at a point of insertion into a channel (24) located underneath said top winding roller (16) by an oscillating pusher (27, 35) which co-operates to insert said cores (12) between said two winding rollers, said re-reeling machine further comprising an arrest element (32, 132) located at a point outside said channel (24) for at least partial arrest of said paper (11) upstream of said point of insertion of said cores (12) and wherein said arrest element for at least partial arrest of said paper is set at one end of said oscillating pusher (27, 35) for tearing said paper (11) upstream of channel (24).
A device for re-reeling and forming a roll of paper in a re-reeling machine comprising three rollers (16, 17, 18) having mutually parallel axes that are perpendicular to the direction of feed of paper (11), wherein said three rollers are supported on a frame, wherein two of said rollers are winding rollers, a bottom winding roller (17) and a top winding roller (16), which co-operate with a third roller (18) that maintains a certain pressure on said roll of paper or log, wherein said third roller (18) is supported by a pair of arms (22) which oscillate with respect to said frame, wherein said paper (11) passes over said top winding roller (16), and a finished roll or log (19) comes out of an outlet aperture or gap (30) located between said bottom winding roller and said third roller, wherein cores (12) for said rolls of paper which are fed one after another by a pusher (15) of conveyor (13) are introduced at a point of insertion into a channel (24) located underneath said top winding roller (16) by an oscillating pusher (27, 35) which co-operates to insert said cores (12) between said two winding rollers said re-reeling machine further comprising an arrest element (132) located at a point outside said channel (24) for at least partial arrest of said paper (11) upstream of said point of insertion of said cores (12) and wherein said arrest element (132) is adjacent said top winding roller (16) on which said arrest element acts, said arrest element (132) being positioned for rotation around a pin (128) of said arrest element (132), where said arrest element is positioned upstream of said channel (24).
