Abstract
A film core for an electrophotographic copying or printing machine comprises a core frame member provided at opposite ends with rollers, such frame member being slightly flexible about a steering axis of one of said rollers, to allow pivotal movement of that roller about the steering axis, but being substantially rigid against any other relative pivotal or translational movement between the ends of the core frame by which the rollers are supported.
