Abstract
A cartridge which contains an inked ribbon for use in a high speed printer such as a wire matrix printer and typically driven by a capstan of the printer. The ribbon is arranged in the form of a mobius loop and the cartridge is constructed in a minimal number of components including a cartridge cover and cartridge base together forming a compartment for most of the loop, and a slotted pinch roller. The cover includes an integral pinch roller support post and part of the means for controlling the twist in the mobius loop. The base includes an integral ribbon peeler associated with the pinch roller and the other part of the control means for the loop twist. The cover and base are provided with ribbon guide means to support the ribbon only along a section thereof between the egress and ingress of the loop to the compartment, leaving a relatively long, linear portion of the ribbon unsupported by the cartridge, thus enabling use of the cartridge either in a stationary position or piggybacked to the printing head.
