ABSTRACT:
An apparatus for constraining a moving web of photographic film includes a first frame (84); a pair of oppositely facing, substantially parallel edge guides (148, 156, 158) supported by the first frame, each edge guide comprising a serpentine contact surface (160) with a central portion (162) for engaging an edge surface of a web moving between the edge guides; a second frame (70, 186, 248); a pair of film deflectors (262, 264) supported by the second frame; and a mechanism (74-96, 180-238) for relatively positioning the two frames with the film deflectors at least partially engaging the film with the serpentine contact surface, the mechanism being selectively adjustable to vary the deflection of the web toward the serpentine path, so that webs of different types of photographic film can be constrained for bar code reading.
