A cartridge for an inked ribbon for type bar typewriters comprises a container adapted to be mounted on one side of the printing point and a terminal part which guides a length of ribbon to the printing point and reverses the direction thereof for reentry of the ribbon into the container. Two return surfaces of the terminal part carry the ribbon reentering the container back at the same height as the emerging ribbon. The container is of elongated shape and is mounted removably on a support on the machine which rocks in front of a platen in such manner that the terminal part of the cartridge is disposed below the printing line. There is provided a mechanism for actuating the inked ribbon which comprises a control element actuatable by the type bars and a toggle joint which rock the cartridge support for effecting a precise raising of the ribbon in response to variable stroke control actuated by the selected key. A control pin is rotatable on the support and is actuated by the control element to engage vertically a driving hub of the cartridge and feeds the inked ribbon in front of the printing point.
