Abstract
Abstract An air texturizer of the type in which the yarn is fed into a chamber with a blast of air, resulting in some twisting of the yarn, and the yarn untwists as it leaves the chamber and is changed in direction, for example at right angles, resulting in the formation of loops as it untwists. More particularly, the present invention is applied to an air texturizer of the type in which yarn is overfed at an angle into a vortex chamber, with a tangential blast of air causing the yarn to spin in the form of a crank or loop and flow out axially with the air and turn its direction. The texturizer is provided with a flange in which a beveled plate on a micrometric threaded shaft is mounted with a polished beveled edge over the axial outlet of the texturizer. This permits a very accurate adjustment of distance which controls the loops on the texturized yarn and permits operating overfeed of yarn. Bulkier yarn can be produced at a high rate of speed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
85 words
In an apparatus comprising a texturizing chamber, means for introducing yarn therein and means for introducing a blast of air causing the yarn to twist, the apparatus also being provided with a substantially axial yarn outlet, the improvement which comprises a conical plate with polished conical surface mounted for micrometric adjustment axially of the texturizer and located so that the conical surface is adjacent but not touching, the axial outlet of the texturizing chamber, whereby improved loop formation in the yarn and bulking is effected.
Claim 2
Dependent Claim
85 words
In an apparatus comprising a texturizing chamber, means for introducing yarn therein and means for introducing a blast of air causing the yarn to twist, the apparatus also being provided with a substantially axial yarn outlet, the improvement which comprises a conical plate with polished conical surface mounted for micrometric adjustment axially of the texturizer and located so that the conical surface is adjacent but not touching, the axial outlet of the texturizing chamber, whereby improved loop formation in the yarn and bulking is effected.
Claim 3
Dependent Claim
56 words
An apparatus according to claim 1 in which the means for introducing yarn into the texturizing chamber is at an angle and the means for introducing air comprises means for introducing air tangentially to produce a vortex beyond the point of yarn introduction, whereby the vortex causes the yarn to spin in loop or crank form.
Claim 4
Dependent Claim
36 words
An apparatus according to claim 1 in which the conical plate is provided with a fine-pitch, threaded shaft mating with a tapped hole in a shoulder extending out from the texturizer end having the axial outlet.
Claim 5
Dependent Claim
24 words
An apparatus according to claim 3 in which the angle of the conical surface is between about 10* and about 15* to the horizontal.
Claim 6
Dependent Claim
24 words
An apparatus according to claim 1 in which the angle of the conical surface is between about 10* and about 15* to the horizontal.
Claim 7
Dependent Claim
60 words
An apparatus according to claim 1 comprising an axial conduit into the texturizing chamber just behind the yarn inlet and means for producing a brief puff of air when a new end of yarn is first introduced whereby the brief puff of axial air pulls the yarn into the texturizing chamber and directs it out through the axial yarn outlet.
Claim 8
Dependent Claim
115 words
A process of texturizing yarn which comprises introducing yarn into a stream of air capable of twisting the yarn, permitting the yarn to untwist, changing its direction and causing it to flow in a narrow zone one boundary of which is an inclined polished surface, introducing a brief puff of air axially behind the yarn and causing a fresh end of yarn to be sucked into the chamber and led out through the chamber, whereby when a new end of yarn is introduced the brief puff of air exerts a self-threading action, the puff being sufficiently brief so that when yarn is being introduced and moved through the chamber the puff ceases and twisting begins.

Dependent Claim
