ABSTRACT:
An apparatus and a method are provided for the slitting and the rolling of elongated sheets of material. The apparatus includes a pair of parallel spaced supporting rollers, a mandrel longitudinally disposed upon both of the supporting rollers, a riding roller being longitudinally disposed upon the mandrel and being guided for movement away from the mandrel, drive means rotating one of the supporting rollers at a predetermined speed and providing predetermined rotational torque to the other supporting roller and to the riding roller, and rider forcing means separately and adjustably forcing each end of the riding roller toward the mandrel.
The apparatus also includes a cylindrically shaped slitting drum having a plurality of longitudinally spaced circumferential grooves thereon and a plurality of disc-shaped slitting knives being mounted on a knife-mounting shaft for movement into meshing engagement with the slitting grooves and for movement into resilient operative contact with one side of each of the grooves.
The method includes placing a mandrel upon a pair of supporting rollers which are in parallel and longitudinal supporting relationship thereto, securing one end of the material to the mandrel, moving a riding roller into longitudinal surface contact with the mandrel distal from the supporting rollers, rotating the first supporting roller at a predetermined speed in the direction that draws the material between the first supporting roller and the mandrel, applying a predetermined rotational torque to the other supporting roller in the direction that provides tensioning of the sheet material on the mandrel, applying a predetermined rotational torque to the riding roller in the direction that provides tensioning of the sheet material on the mandrel, and separately and adjustably urging both ends of the riding roller into contact with the material being wound on the mandrel.
