ABSTRACT:
A method and apparatus for manufacturing a multi-component yarn as well as a multi-component yarn produced thereby, in which staple fibers and at least one endless yarn are combined with each other in a defined manner such that a wrapped yarn will result which purely externally has as far-reachingly as possible the properties of a pure staple fiber yarn; the sliver and the endless yarn or yarns are fed separately to a feed roller pair, are combined thereat travelling at the same velocity and parallel to one another, and are subsequently exposed together to a false twist and finally wrapped by a fine-count binding yarn; the predominantly nonvisible part of the wrapped yarn is constituted by the endless yarns which render the yarn bulky with relatively low material expenditure.
