The invention relates to a dog (3) arranged inside a feed reel (1) for the carbon ribbon (2) of a typewriter. The dog (3) has the form of a cylinder with two projecting flanges (4,5) extending in two slots (11,12) of the feed reel. The lower part of the dog has a slot (9) in which the drive shaft pin (7) of the typewriter engages. Power transmission thus takes place from the drive shaft (8) via the dog (3) to the feed reel (1). |
