ABSTRACT:
Apparatus for advancing roll films in a copying machine on a table which is located above the floor at a level less than the length of a film. The apparatus has a film channel and advancing rolls which can engage one end portion of a film to advance the film past a monitoring device preparatory to copying and/or past a copier subsequent to monitoring. The other end portion of the film is frictionally or clampingly held in a recess or on a supporting surface adjacent the inlet of the film channel so that the median portion of the film forms a loop which does not reach the floor beneath the table. A wiping device with two brushes can be installed adjacent the recess to wipe both sides of the film while the film advances into the channel so that the size of its looped portion is reduced.
