ABSTRACT:
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.
