Patent ID: 6889493

Claim:
Apparatus for forming splicing a first and a second yarn comprising: a yarn conduction member having a first and a second yarn conduction channel extending therethrough, each channel having a predetermined dimension, and an intermingling jet disposed adjacent to the yarn conduction member for forming an air entangled splice between the first and second yarns, the yarn conduction member having a first and second knife blade disposed adjacent to one of the yarn conduction channels, each knife blade having a tip thereon, each blade having a passage defining a cutting edge formed in one portion thereof and a solid portion disposed between the passage and the tip of the blade, the length of the solid portion of the blade being at least equal to the dimension of the passage to which the blade is adjacent, the first and second knives being insertable into and retractable from the channel adjacent thereto, in the inserted position the passage in the knife aligning with the channel adjacent thereto, in the retracted position the solid portion of the blade interdicting the passage to prevent movement of a yarn therethrough, movement of each knife from the inserted to the retracted positions bringing the cutting edge into operative cutting contact with the yarn conduction member, thereby to sever a yarn extending through the passage in the knife.
