Process for cleaning transport rolls of film developing apparatus

Abstract

Abstract A process of cleaning the film transport rolls of developing apparatus having a transport system comprising a plurality of pairs of rolls for transporting the film from an inlet through successive aqueous baths and a drying section and out of a discharge, some of the rolls being above and others below the liquid level in the baths comprises passing lengthwise through the transport system of the apparatus a rectangular sheet of fleece material having fibers oriented parallel to one another and to the longitudinal edges of the sheet. The fibers are made of a material which is substantially free of swelling by the action of the baths of the developing apparatus. However, the liquid of the baths is absorbed in the interstices between the fibers of the fleece material so that as the cleaning material passes along the transport system it moistens those rolls which are above the liquid level and may have dried out. Any soluble impurities on such rolls are thereby dissolved. Any insoluble impurities on rolls above or below the liquid level are passed into the interstices between the fibers of the fleece material and are carried away by the material.
