Patent ID: 6945491

Claim:
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 ).
