Abstract: Apparatus for wiping moisture off the sides of running webs of photosensitive material in developing machines employs one or more deformable elastic wiping elements in the form of elongated lips or rings which are maintained in contact with the respective side or sides of the running web. Each wiping element extends transversely of the path of the running web and is imparted a movement having a component in a direction transversely of the running web. This reduces the likelihood of extensive localized wear upon the wiping element or elements.

Abstract: The fixing arrangement comprises a heated aluminum plate heating the lower face of a tone-image-bearing copy paper. The heated plate comprises two transverse ribs extending transverse to the copy-paper transport direction and, intermediate them, a sequence of transversely spaced longitudinal ribs, the transverse and longitudinal ribs intersecting to form individual recessed rectangular fields, each of which, when closed off from above by the copy paper, confines air heated by the heating plate to form a transversely extending zone of hot-air air cushions heating the lower face of the paper. Transversely extending suction channels located upstream and downstream of the hot-air air-cushion zone contain transversely extending rows of suction apertures, for holding the sheet down against the ribs and closing off the individual hot-air air cushions.
