  • Method and apparatus for the manufacture of fancy yarns
    Patent number: 4566259
    Abstract: A method and apparatus for producing a fancy yarn, in which a core and effect yarn 5 are fed along a path to a false twist device 6 and a binding yarn 4 is fed via a rotating component 1 adjacent the path, the component rotating about an axis transverse to the path, and having a yarn guiding portion 3 radially spaced from the axis, whereby the binding yarn is caused to perform a reciprocating, oscillating motion with respect to the core and effect yarns.

  • Process for the manufacture of a fancy yarn, and products obtained
    Patent number: 4528807
    Abstract: Process for the manufacture of a fancy yarn having stable protuberances along its length, wherein at least one effect yarn is fed onto a core yarn at a greater speed than the latter, the protuberances thus produced and the core yarn being bound together by the combination of feeding of the effect yarn in an oscillating manner relative to the core yarn and increasing the twist of the assembly passing through a simple false twist device, without the need for heat setting means.
