摘要 |
A drag roller device for a printing apparatus comprises a cleaning means for cleaning a drag roller. The cleaning means is in contact with a part of the circumferential surface of the drag roller except for the circumferential area around which a printed continuous sheet fed from a printing section is wound. The cleaning means may be movable within the circumferential area of the drag roller or separable from it. The cleaning means may be supplied with a cleaning liquid. In the drag roller device thus constructed, the cleaning means can remove various stains and/or spots of ink transferred from the circumferential surface of the drag roller and/or additional rollers at each revolution of the drag roller. This cleaning operation of the cleaning means ensures to prevent the printed surface of the continuous sheet succeedingly fed from damaging with the stains and spots of ink from the drag roller and so on.
