Abstract

False-twisted yarn strands are separately carried around a guide wheel and the nodes thereof are brought together and locked by mechanical entanglement, after which the strands are self-twisted. Embodiments of entanglement joining devices include reciprocating friction plates which rub the fibers together and twist them, causing joining, the plates being carried on the guide wheel. A needle punching device carried by the wheel is disclosed, the needles being reciprocated by a cam structure within the wheel. In a third embodiment edges of oppositely rotating overlapping discs contact and twist fibers in the node area, causing entanglement.
