摘要

A normally frictionally driven carbon ribbon take up spool rotatively supported within a machine mounted holder is provided with a curved slot in an outer flange which extends from the spool core to its periphery in the direction of rotation of the spool. The flange adjacent to the peripheral portion of the slot is off-set outwardly to catch and draw a guided ribbon held in its path down to and to wind it on the core. The torque of the frictional drive effective on the spool and the turning moment prevalent at the root of the spool slot, are such that several ribbon winding turns on the spool core can be accomplished before the frictional drive slips.
