Rewinding machine for longitudinally slit webs of paper

Abstract

The application relates to an improvement in a rewinding machine for continuous individual webs of paper cut from a wider web, and including a backing cylinder, a plurality of winding shafts alternately arranged diametrically opposite one another relative to the backing cylinder, a roll on each of the winding shafts, and bearing blocks for each of the rolls, whereby the individual webs contact the backing cylinder and alternate individual webs are taken up on the rolls arranged on the winding shafts on each side of the backing cylinder, the bearing blocks permitting the shafts and rolls to move away from the backing cylinder as the roll diameters increase due to webs wound thereon, all known in the art. In accordance with the invention, a bearing block on one side of the backing cylinder is coupled with a bearing block on the other side of the backing cylinder, the coupled bearing blocks constituting those which define a plane of division between two adjacent individual webs, and means are provided for displacing the coupled bearing blocks along the axis of the backing cylinder, whereby in adjusting the rewinding machine to accept individual webs of different widths by displacement of the bearing blocks on both sides of the backing cylinder, the coupling of the bearing blocks ensures that opposite blocks are properly aligned to define planes of division.
