ABSTRACT:
A system is provided for movably supporting an ink film in a printer. The system has cylindrical supply and take-up cores for supporting and taking up the film during printing operations. The cores may be made of molded plastic resin. The ends of the cores are sized to selectively fit within a frame in such a way as to provide stable operation, including where applicable, while a frame cover is closed. In a preferred embodiment, the diameters of the first and second ends of the supply and take-up cores are essentially the same, and the diameters of the second and first ends of the respective cores are essentially the same. A molded cylindrical brake portion frictionally contacts the teeth of a brake gear to provide the desired film tension with improved handling and with reduced likelihood of jamming.
