Fluid-jet twist-inserting apparatus and method
First Claim
1. An apparatus for inserting twist into a moving strand, comprising:
- (a) a first body and a second body, each of said first and second bodies including;
(i) an orifice extending therethrough for permitting passage of a moving yarn;
(ii) an air channel extending therethrough and communicating with said orifice; and
(iii) said air channel communicating with said orifice at a tangentially-offset angle to the path of the yarn through the orifice to create a cyclonic air circulation pattern in the orifice to insert a predetermined direction of twist into the yarn as the yarn passes through the orifice;
(b) said first body inverted relative to, and in overlying alignment with, said second body whereby the air channel of the first body inserts one predetermined direction of twist into the yarn and the air channel of the second body inserts another predetermined direction of twist into the yarn;
(c) selection means for selecting one or the other of the first body or second body air channels to deliver air to the respective the orifice of one or the other of the first body or the second body and thereby insert a predetermined direction of twist into the yarn; and
(d) a top end block and a bottom end block between which said first and second bodies are sandwiched; and
(e) air supply ports extending through said top end block and communicating with respective air channels in the first and second bodies.

Abstract
An apparatus for inserting twist into a moving strand, including a first body including an orifice extending therethrough for permitting passage of a moving yarn. An air channel extends therethrough and communicates with the orifice. The air channel communicates with the orifice at a tangentially-offset angle to the path of the yarn through the orifice to create a cyclonic air circulation pattern in the orifice to insert a predetermined direction of twist into the yarn as the yarn passes through the orifice. The first body is adapted for being inverted relative to, and placed in overlying registration with, a second like body whereby the air channel of the first body inserts one predetermined direction of twist into the yarn and the air channel of the second body inserts another predetermined direction of twist into the yarn.

12. An apparatus for inserting twist into a moving strand, and comprising:
-
(a) a first disk including; (i) an orifice extending therethrough for permitting passage of a moving yarn; (ii) an air channel extending therethrough and communicating with said orifice; and (iii) said air channel communicating with said orifice at a tangentially-offset angle to the path of the yarn through the orifice to create a cyclonic air circulation pattern in the orifice to insert a predetermined direction of twist into the yarn as the yarn passes through the orifice; (b) a second disk including; (i) an orifice extending therethrough for permitting passage of a moving yarn; (ii) an air channel extending therethrough and communicating with said orifice; and (iii) said air channel communicating with said orifice at a tangentially-offset angle to the path of the yarn through the orifice to create a cyclonic air circulation pattern in the orifice to insert a predetermined direction of twist into the yarn as the yarn passes through the orifice; (c) said first disk inverted relative to, and placed in overlying alignment with, said second disk; and (d) top and bottom end blocks enclosing said first and second disks, said top end block including air supply ports extending therethrough and communicating with respective air channels in the first and second disks for supplying pressurized air thereto, whereby the air channel of the first disk inserts one predetermined direction of twist into the yarn and the air channel of the second disk inserts another predetermined direction of twist into the yarn. - View Dependent Claims (13, 14)
