Abstract:
1. A winding apparatus used in a slitter in which a plurality of winding arms are spaced from each other to constitute adjacent pairs, a winding roll being interposed between and supported by each of the pairs of winding arms, a drive motor being provided on one or both of each of the pairs of winding arms, the winding rolls being rotated by the drive motors to wind webs about the winding rolls after slitting a web material into the webs, the apparatus comprising: the drive motor including a body and a rotating shaft, the rotating shaft passing through the body to protrude on opposite sides of the body, the drive motor further including a hollow shaft, the rotating shaft being fitted into the hollow shaft, the rotating shaft and the hollow shaft being restrained from being rotated relatively to each other so that the rotating shaft and the hollow shaft are rotated integrally with each other; a pair of bearings provided on the winding arm on which the drive motor is provided, the rotating shaft being supported for rotation by the bearings on the opposite sides of the body; the rotating shaft and the hollow shaft being connected to the winding roll at a predetermined position between the bearings to make the winding roll rotatable; and a restrainer provided between the winding arm and the body, the body being restrained from being rotated by the restrainer in a rotating direction of the rotating shaft; wherein the drive motors are disposed coaxially to each other so that the rotating shafts are connected to each other.
