ABSTRACT:
A cartridge for a correction ribbon for typewriters comprises a container for a supply reel and a receiving reel. A tensioning device comprises a toothed ring on the supply rell and a spring which is pivoted in the container and which has one end engaged with the toothed ring to tension the ribbon. The container can be removably fixed to the lower part of a cartridge for a typing ribbon which in turn can be fitted on a support of the machine. The support is movable from a viewing position to a typing position in which the typing ribbon is in front of the point of typing and to a correction position in which the correction ribbon is in front of the point of typing. The receiving reel of the cartridge, in use, is capable of co-operating with a feed mechanism which provides for forward feed movement of the ribbon in each correction cycle. For that purpose the receiving reel comprises a series of frontal teeth provided in the lower part of its flange, the container comprises an opening and the feed mechanism comprises a ratchet co-operating with the frontal teeth through the opening for a forward feed cycle of the correction ribbon when the support moves between the viewing position and the correction position.
