US3936916A — Method and apparatus for the production of textur…

Claim 1

Independent Claim 126 words

A method comprising: passing a yarn to be textured to a yarn texturing zone; and passing the yarn directly to a restraining zone in which a yarn wad forms, said restraining zone containing a rigid sleeve, a plurality of individual stacked members and a flexible sleeve through which the yarn wad passes, said rigid sleeve being positioned intermediate the yarn wad and the stacked members to assist in guiding the yarn wad through the restraining zone, said flexible sleeve being of substantially uniform diameter and being positioned intermediate the yarn wad and the stacked members so as to prevent said stacked members from being removed from said restraining zone by becoming entrained in the yarn wad as the stacked members confine and restrain the yarn wad.

Claim 2

Independent Claim 126 words

A method comprising: passing a yarn to be textured to a yarn texturing zone; and passing the yarn directly to a restraining zone in which a yarn wad forms, said restraining zone containing a rigid sleeve, a plurality of individual stacked members and a flexible sleeve through which the yarn wad passes, said rigid sleeve being positioned intermediate the yarn wad and the stacked members to assist in guiding the yarn wad through the restraining zone, said flexible sleeve being of substantially uniform diameter and being positioned intermediate the yarn wad and the stacked members so as to prevent said stacked members from being removed from said restraining zone by becoming entrained in the yarn wad as the stacked members confine and restrain the yarn wad.

Claim 3

Dependent Claim 59 words

The method of claim 1 wherein said texturing zone is a fluid jet texturing zone, said flexible sleeve has porous walls wherein the pores are of sufficient size to allow passage of a fluid used in the fluid jet texturing zone but to prevent passage of said stacked members, and said restraining zone also functions as a cooling zone.

Claim 4

Dependent Claim 20 words

The method of claim 1 wherein the stacked members comprise balls and the rigid sleeve comprises a plurality of rods.

Claim 5

Dependent Claim 13 words

The method of claim 3 wherein the balls include balls of different sizes.

Claim 6

Dependent Claim 25 words

The method of claim 1 wherein said flexible sleeve is constructed from a material selected from the group consisting of nylon, polyester, polyolefin and polytetrafluoroethylene.

Claim 7

Dependent Claim 147 words

Apparatus for restraining a yarn wad comprising: a yarn texturing means having an inlet and an outlet; a chamber having an inlet and an outlet and an inner and outer surface, said inlet attached to the outlet of the texturing means; a flexible sleeve having a substantially uniform diameter and having an inlet and an outlet and an inner and an outer surface, said inlet of said sleeve being attached to the outlet of said texturing means and said sleeve being positioned in and extending through said chamber; a plurality of individual stacked members positioned in said chamber between the inner surface thereof and the outer surface of said flexible sleeve; and a rigid sleeve disposed in said chamber adjacent the inlet thereof and extending therethrough to form an extension of said inlet, said rigid sleeve constructed so as to permit the stacked members to pass therethrough.

Claim 8

Dependent Claim 147 words

Apparatus for restraining a yarn wad comprising: a yarn texturing means having an inlet and an outlet; a chamber having an inlet and an outlet and an inner and outer surface, said inlet attached to the outlet of the texturing means; a flexible sleeve having a substantially uniform diameter and having an inlet and an outlet and an inner and an outer surface, said inlet of said sleeve being attached to the outlet of said texturing means and said sleeve being positioned in and extending through said chamber; a plurality of individual stacked members positioned in said chamber between the inner surface thereof and the outer surface of said flexible sleeve; and a rigid sleeve disposed in said chamber adjacent the inlet thereof and extending therethrough to form an extension of said inlet, said rigid sleeve constructed so as to permit the stacked members to pass therethrough.

Claim 9

Dependent Claim 31 words

The apparatus of claim 6 wherein said yarn texturing means is a fluid jet and said flexible sleeve has a cross-sectional area larger than the outlet of the yarn texturing means.

Claim 10

Dependent Claim 11 words

The apparatus of claim 6 wherein said stacked members comprise balls.

Claim 11

Dependent Claim 13 words

The apparatus of claim 8 wherein said balls include balls of different sizes.

Claim 12

Dependent Claim 26 words

The apparatus of claim 6 wherein said rigid sleeve comprises a plurality of rigid members spaced from one another and generally defining a rigid cylindrical sleeve.

Claim 13

Dependent Claim 16 words

The apparatus of claim 10 wherein said rigid members are rods positioned inside said flexible sleeve.

Claim 14

Dependent Claim 23 words

The apparatus of claim 6 wherein the flexible sleeve is constructed from a material selected from the group consisting of nylon, polyester, polytetrafluoroethylene.

Claim 15

Dependent Claim 19 words

The apparatus of claim 6 wherein said stacked members are completely enclosed by said chamber and said flexible sleeve.
