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.

Spliced yarn and method for forming the same

Apparatus for forming a spliced yarn includes a yarn conduction member with an intermingling jet disposed forwardly thereof. The yarn conduction member has respective yarn conduction channels through which the first and second yarns are conveyed to the intermingling jet. The yarn conduction member has a first and second knife blade disposed adjacent to one of the yarn conduction channels. The first and second knives are insertable into and retractable from the channel to which they are adjacent. In the inserted position the passage in the knife aligns with the channel into which it is inserted, while in the retracted position the solid portion of the blade interdicts the passage to prevent movement of a yarn therethrough.
