ABSTRACT:
A ribbon feed mechanism for printing machines has a toothed wheel rigidly mounted on a drive shaft at an angle relative to a plane perpendicular to the drive shaft axis. The toothed wheel will penetrate layers of outer convolutions of a roll of film ribbon on a take-up spool at varying locations relative to the ribbon width for feeding the film ribbon with equal length increments more consistently.
