Abstract
A textile yarn ring spinning or twisting apparatus of the type comprising a spindle for carrying a yarn support tube, the spindle being rotatable about its axis to enable yarn to be wound on the tube to form a yarn package, a yarn reserve winding member around which yarn may be wound prior to the doffing of a wound package from the spindle, and a yarn severing device so positioned adjacent the axis of the spindle and between the reserve winding member and an adjacent portion of the spindle on which the end of the package is located as to engage yarn extending from the reserve winding member to the wound package on the spindle. In accordance with the invention the drive mechanism enables relative rotation between the reserve winding member and the severing device so that the length of yarn extending from the package on the spindle to the reserve winding member may be severed.
