Abstract:
A device for controlling winding of a roll of paper or â€œlogâ€  in a re-reeling machine comprising, on a frame (20), a set of three rollers arranged with their axes parallel to one another and perpendicular to the direction of feed of the paper, comprising two winding rollers (15, 16), a top one (15) and a bottom one (16), designed to co-operate with a third roller (17) which exerts a certain pressure on a roll of paper or log being formed, the first two rollers (15, 16) being supported on the frame (20), and the third roller (17) being carried by a pair of arms (21) that are free to oscillate with respect to the frame (20), the paper being wound passing over one of the two rollers (15, 16), and the finished roll (14) coming out of an output gap (43) identified between the bottom roller (15) and the third roller (17), characterized in that the third roller (17) and the pair of arms (21) are set on a moving element (24) displaceable according to a direction (28) oscillating within an angle (&agr;) with respect to a direction parallel to a direction of growth (29) of the roll being formed.
