ABSTRACT:
A holding device for temporarily holding the free end of a typing or printing ribbon to permit it to be automatically wound around the core of a takeup reel in an automatic ribbon fastening system. The reel has one flange part provided with a threading slit whose width increases toward the outer edge of the flange part from an inwardly located ribbon-gripping portion. The holding device temporarily holds the free end stationary under slight tension so that the ribbon extends across the flange part. As the reel is rotated, the ribbon enters the threading slit and slides radially inwardly until it is gripped by the gripping portion. As the reel continues to rotate, the free end of the ribbon is pulled out of the holding device.
