Abstract
A method for producing a spliced yarn comprising alternating predetermined lengths of a first and a second yarn and to the yarn is disclosed. A predetermined length of a first yarn is drawn through an intermingling jet. A leading portion of a second yarn is forwarding into the intermingling jet and into overlapping relationship with a trailing portion of the first yarn. The yarns are held in the intermingling jet, as by a clamp disposed forwardly of the jet. Using a pressurized fluid the overlapped portions are intermingled. The first yarn is then severed, and the spliced portion and a predetermined length of the second yarn are drawn through the intermingling jet. The cycle is repeated with the second yarn being the currently drawn yarn and the first yarn being forwarded into overlapping relationship therewith.
