Abstract
A transparency film assemblage having a film frame of the instant or self-developing type and a roller assembly specifically adapted for use with the assemblage during the spreading of a processing liquid between an emulsion side of the film frame and a strip sheet. The film assemblage includes a sheet of material having a tab at one end which when pulled, subsequent to the spreading of the processing liquid between the film frame's emulsion side and a strip sheet, removes the strip sheet from covering relation with the film frame while simultaneously covering the film frame's emulsion layer which is now attached to the strip sheet. The roller assembly includes a pair of rollers which are configured to provide a sequence of gaps having varying predetermined thicknesses during the movement of a film assemblage therebetween.
