ABSTRACT:
A photo filmstrip (14) of a regular length (L) is produced from photo film web (45) having a predetermined width (W). The photo filmstrip and the photo film web have a back surface, an emulsion surface, a pair of lateral edge faces (45a), and four corner edges (45b, 45c) defined between the back surface, the emulsion surface, and the lateral edge faces. At least one of the lateral edge faces and at least one of the corner edges of the photo film web are abraded while the photo film web is conveyed. Photo film dust, created in the abrasion is eliminated from the photo film web. Perforations (34) are formed in the photo film web. The photo film web is cut by the regular length into the photo filmstrip, which is wound into a cassette shell.
