Abstract
Abstract A permanent zig-zag crimp or helical configuration is imparted to a length of yarn, thread, tow or continuous filament textile material by extruding the length of yarn from a high pressure chamber, after which the yarn impinges on obstructing means for the imparting of the crimp. The length of yarn is held in the crimped state and heated in order to form a permanent set, followed by cooling of the strip of yarn. The extrusion opening in the high pressure chamber through which the yarn is extruded is substantially equal in cross-section to the cross-section of the yarn in order to achieve extrusion of the yarn from the high pressure chamber.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
83 words
Apparatus for imparting a texture to yarn comprising a chamber having an opening substantially corresponding in crosssection to the cross-section of said yarn, a source of pressurized fluid in communication with said chamber, and obstruction means disposed adjacent said opening externally of the chamber in ambient air whereby when said yarn is threaded through said opening and pressurized fluid is provided in said chamber, the yarn is extruded from the chamber and impinges on said obstructing means resulting in texturing of the yarn.
Claim 2
Dependent Claim
83 words
Apparatus for imparting a texture to yarn comprising a chamber having an opening substantially corresponding in crosssection to the cross-section of said yarn, a source of pressurized fluid in communication with said chamber, and obstruction means disposed adjacent said opening externally of the chamber in ambient air whereby when said yarn is threaded through said opening and pressurized fluid is provided in said chamber, the yarn is extruded from the chamber and impinges on said obstructing means resulting in texturing of the yarn.
Claim 3
Dependent Claim
26 words
Apparatus for imparting a texture to yarn as in claim 1 further including means for heating said textured yarn, and means for cooling said textured yarn.
Claim 4
Dependent Claim
20 words
Apparatus for imparting a texture to a length of yarn as in claim 1 wherein the pressurized fluid is steam.
Claim 5
Dependent Claim
37 words
Apparatus for imparting a texture to yarn as in claim 1 further including metering rolls disposed in said chamber, said yarn being passed through the nip of said metering rolls prior to being threaded through said opening.
Claim 6
Dependent Claim
23 words
Apparatus for imparting a texture to yarn as in claim 1 wherein the fluid pressure within the chamber is greater than 100 p.s.i.g.
Claim 7
Dependent Claim
70 words
Apparatus for imparting a texture to yarn as in claim 1 further including a pair of metering rolls disposed in said chamber for metering the yarn prior to its extrusion from the chamber, and further including a pair of crimping rolls disposed externally of the chamber, the nips of said crimping rolls defining the obstruction means, and means for coordinating the rotating of said metering rolls and said crimping rolls.
Claim 8
Dependent Claim
53 words
Apparatus for imparting a texture to yarn as in claim 1 wherein said chamber is provided with a second opening, said second opening substantially corresponding in cross-section to the cross-section of said yarn, which yarn is, in turn, threaded through said second opening, through said pressurized chamber, and through said first extrusion opening.
Claim 9
Dependent Claim
17 words
Apparatus for imparting a texture to yarn as in claim 1 wherein said pressurized fluid is air.
Claim 10
Dependent Claim
51 words
Apparatus for imparting a texture to yarn as in claim 1 wherein said obstruction means comprises of a pair of spaced, roller mounted belts, and further including heating means and cooling means disposed in the vicinity of said belts in order to successively heat and cool the textured yarn passing therethrough.
Claim 11
Dependent Claim
32 words
Apparatus for imparting a texture to yarn as in claim 1 wherein said chamber includes two relatively moveable portions thereof defining the opening corresponding in cross-section to the cross-section of said yarn.
Claim 12
Dependent Claim
63 words
Apparatus for imparting a texture to yarn as in claim 1 wherein the obstruction comprises a roller driven porous belt, the outside surface of said belt receiving the yarn extruded from said opening, while the inside surface of said belt is in communication with a source of reduced pressure, and further including heating means for heating said crimped yarn to permanently set same.
Claim 13
Dependent Claim
37 words
Apparatus for imparting a texture to yarn as in claim 1 wherein a high viscous fluid is provided in the region of said extrusion opening to define an air-tight seal therewith through which said yarn is extruded.
Claim 14
Dependent Claim
86 words
Apparatus for imparting a texture to yarn as in claim 1 wherein said opening is defined by a porous metal plug fixedly secured in the wall of said chamber, which plug includes an opening through which the yarn is threaded, said plug further including a peripherial manifold which is in communication with a source of high pressure fluid, which fluid passes through the porous metal plug to the vicinity of said opening in the plug for forming an air-tight seal through which the yarn is extruded.
Claim 15
Dependent Claim
66 words
Apparatus for imparting a texture to yarn as in claim 1 wherein said pressurized chamber includes a transverse opening extending transverse to the longitudinal axis of said opening, and a source of pressurized fluid in communication with said transverse opening so as to provide a continuous source of pressurized high viscous fluid to the opening for forming an air-tight seal through which said yarn is passed.
Claim 16
Independent Claim
60 words
A method of imparting a texture to yarn comprising the steps of: extruding said yarn from a pressurized contain to ambient air through an opening therein corresponding in cross-section to the cross-section of said yarn; and causing said yarn to impinge on an obstructing means in ambient air disposed externally of said pressuirzed chamber in the vicinity of said opening.
Claim 17
Independent Claim
60 words
A method of imparting a texture to yarn comprising the steps of: extruding said yarn from a pressurized contain to ambient air through an opening therein corresponding in cross-section to the cross-section of said yarn; and causing said yarn to impinge on an obstructing means in ambient air disposed externally of said pressuirzed chamber in the vicinity of said opening.
Claim 18
Dependent Claim
35 words
A method for imparting a texture to a length of yarn as in claim 15 further including the steps of: heating said yarn to form a permanent set in the yarn; and cooling said yarn.
