Abstract: Typewriter carbon ribbon is automatically attached to a takeup reel by the combined provision of: (1) a flexible camming plate that creates significant friction interaction between the reel and the ribbon and is constructed to be effective even when substantial amounts of ribbon have been previously wound on the reel; (2) an electrically neutral flange to eliminate the adverse effects of static electricity on automatic attachment; (3) a reel enclosure for maintaining loose ribbon in the proximity of the reel; (4) several selective control modes of operation to assist the operator; and (5) several other features of construction relating principally to effective handling of a loose flimsy ribbon end.
