ABSTRACT:
A method for feeding a yarn to a textile machine selectively under conditions of positive and capstan feed. The method comprises wrapping multiple turns of yarn around a feed wheel and a smooth, straight-sided upstanding member alongside the feed wheel and inclined to the rotary axis of the feed wheel, and driving the feed wheel by frictional contact with a flexible tape that extends over only a part of the axial extent of the feed wheel. The positive feed mode is established by passing the yarn repeatedly through the nip of the tape and feed wheel. The capstan feed mode is established by feeding the yarn away from the nip. In either mode, separation of successive turns of yarn is achieved by the upstanding member, and when guiding the yarn from one mode to the other there is an axial movement of the yarn turns over the upstanding member to obtain free and unobstructed re-positioning of those turns on the said member.
