  • Patent number: 5407056
    Abstract: An apparatus and a method for distributively feeding a plurality of winding bobbins to predetermined locations, wherein the winding bobbins can simultaneously be fitted onto a rotational shaft without the necessity for large-sized equipment. The apparatus includes a distributing section to which a plurality of winding bobbins are fed while arranged in side-by-side relationship as seen in the axial direction. The distributing section includes a plurality of inclined surfaces so as to allow the winding bobbins to be supported from below. After the winding bobbins are placed on the inclined surfaces, they are distributively fed to the predetermined location along the inclined surfaces in the specifically determined direction.

  • Patent number: 4953252
    Abstract: A roll surface cleaning device for cleaning a roll surface includes a cleaning material strip which is softer than the roll surface and is in a continuous length. The cleaning material strip is fed out from a feed-out roll and is taken up by a takeup roll. Between the feed-out roll and the takeup roll, the cleaning material strip is pressed against the roll surface by a pressing mechanism and captures dirt on the roll surface. A first sucking mechanism applies suction force to the portion of the cleaning material strip pressed against the roll surface so that the dirt which has been captured on the cleaning material strip is removed therefrom or is embedded therein by suction. A vibration generator imparts fine vibration to the pressing mechanism. A second sucking mechanism is provided between the first sucking mechanism and the takeup roll and applies suction force to the cleaning material from the side opposite to the side which is pressed against the roll surface.
