Abstract
Abstract A device for the production of yarns having interlaced strands which includes a first plate having a passage for the yarn therethrough; a second plate having a passage for the yarn therethrough aligned with the passage of the first plate and a surface in abutting relation to a surface of the first plate; and at least two curved conduits defined by recesses in at least one of the abutting surfaces of the first and second plates, such conduits communicating with the passages through the first and second plates. Means is provided to hold the yarn in a substantially constant position when traveling through the passages of the first and second plates and the curved conduits converge substantially tangentially toward such means to hold the yarn in place. When a rapidly moving fluid, e.g. air, is passed through the curved conduits the same impinges upon the yarn and interlaces the same.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
180 words
A device for the production of a yarn having interlaced strands produced by impinging a rapidly moving fluid upon a moving yarn, including: a. a first plate having a passage therethrough through which the yarn travels; b. a second plate having a passage therethrough through which the yarn travels, said passage of said second plate being aligned with said passage of said first plate, said second plate having a surface in abutting relation with a surface of said first plate, at least one of the abutting surfaces having recesses therein; c. means to hold said yarn in a substantially constant position when traveling through said passages of said first and second plates and the rapidly moving fluid impinges thereupon; d. at least two curved conduits defined by said recesses in said at least one of said abutting surfaces of said first and second plates, said conduits communicating with said passages through said first and second plates and converging substantially tangentially toward said means to hold said yarn; and e. means to supply a rapidly moving fluid to said curved conduits.
Claim 2
Independent Claim
180 words
A device for the production of a yarn having interlaced strands produced by impinging a rapidly moving fluid upon a moving yarn, including: a. a first plate having a passage therethrough through which the yarn travels; b. a second plate having a passage therethrough through which the yarn travels, said passage of said second plate being aligned with said passage of said first plate, said second plate having a surface in abutting relation with a surface of said first plate, at least one of the abutting surfaces having recesses therein; c. means to hold said yarn in a substantially constant position when traveling through said passages of said first and second plates and the rapidly moving fluid impinges thereupon; d. at least two curved conduits defined by said recesses in said at least one of said abutting surfaces of said first and second plates, said conduits communicating with said passages through said first and second plates and converging substantially tangentially toward said means to hold said yarn; and e. means to supply a rapidly moving fluid to said curved conduits.
Claim 3
Dependent Claim
27 words
The device of claim 1 wherein said means to hold said yarn in a substantially constant position is a solid obstacle toward which said curved conduits converge.
Claim 4
Dependent Claim
44 words
The device of claim 1 wherein said means to hold said yarn in a substantially constant position is a pneumatic means adapted to supply a rapidly moving fluid in a direction substantially opposite that of said fluid impinging said yarn from said curved conduits.
Claim 5
Dependent Claim
16 words
The device of claim 3 wherein said pneumatic means is at least one auxiliary fluid jet.
Claim 6
Dependent Claim
29 words
The device of claim 1 wherein said at least two curved conduits are defined by recesses in only one of said abutting surfaces of said first and second plates.
Claim 7
Dependent Claim
28 words
The device of claim 1 wherein said at least two curved conduits are defined by recesses in both of said abutting surfaces of said first and second plates.
Claim 8
Dependent Claim
48 words
The device of claim 1 wherein said first and second plates are held in abutting relation by means of projections from the abutting surface of one of said first and second plates and mating apertures in the abutting surface of the other of said first and second plates.
Claim 9
Dependent Claim
41 words
The device of claim 7 wherein said projections from the abutting surface of one of said first and second plates are located in said curved conduits so as to prevent free circulation of said rapidly moving fluid in said curved conduits.
Claim 10
Dependent Claim
12 words
The device of claim 1 wherein said curved conduits are axially staggered.
Claim 11
Dependent Claim
16 words
The device of claim 1, further including auxiliary conduits for delivery of said rapidly moving fluid.
Claim 12
Dependent Claim
12 words
The device of claim 10 wherein said auxiliary conduits are radial conduits.
Claim 13
Independent Claim
57 words
A method of interlacing a yarn by means of a rapidly moving fluid which comprises impinging the rapidly moving fluid in a plane substantially perpendicular to the passage of said yarn simultaneously from at least two curved conduits whereby said fluid while maintaining said yarn against a positioning means impinges said yarn in a substantially tangential manner.
Claim 14
Independent Claim
57 words
A method of interlacing a yarn by means of a rapidly moving fluid which comprises impinging the rapidly moving fluid in a plane substantially perpendicular to the passage of said yarn simultaneously from at least two curved conduits whereby said fluid while maintaining said yarn against a positioning means impinges said yarn in a substantially tangential manner.
Claim 15
Dependent Claim
12 words
The process of claim 12 wherein said rapidly moving fluid is air.
