ABSTRACT:
A film processor in which a length of sheet material is removed from a supply reel, coated with a layer of processing liquid, and directed to a laminating station whereat it is superposed with a photographically exposed premounted film frame of the instant type to initiate the formation of a visible image within the film frame. The processer includes guide means for directing the sheet material from the supply reel to the laminating station comprising a pair of rollers about which the sheet material is partially wound. The pair of rollers are mounted for simultaneous movement toward and away from a processing liquid applicator so as to intermittently coat the sheet material with a layer of the processing liquid. During such movement, the axes of the rollers move in parallel with a first plane in which the sheet material approaches the rollers and with a second plane in which the sheet material moves away from the rollers, thus keeping the total length of the first and second paths constant. This construction obviates changes in the rate of movement of the sheet material between the supply reel and the laminating station during intermittent coating of the sheet material.
