ABSTRACT:
A yarn conveying apparatus is disclosed, and which comprises a pair of circular discs, each having a yarn engaging front surface. The discs are mounted for rotation about respective axes which are inclined with respect to each other, and such that portions of the respective yarn engaging front surfaces are disposed in a closely adjacent opposing face-to-face relationship and define a yarn advancing zone therebetween. The discs are resiliently biased toward each other at the yarn advancing zone, and so that the discs are adapted to engage and advance a yarn which is guided through the advancing zone, without substantial slippage.
