Roll surface cleaning device

摘要

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.
