Abstract

A device for texturizing strand material into a wool-type product includes outer and inner nozzle sections. The outer and inner nozzle sections interface and define a passage through which the strand material travels. A locking device in the inner nozzle section is operable to selectively stop movement of the strand material. The locking device includes a seal holder that positions a sealing member within the inner nozzle section to prevent debris from entering the inner nozzle section, thereby promoting continued effective operation of the locking device. The outer nozzle section includes an end nozzle assembly including a hardened outlet tube. The hardened outlet tube is distinct from the outer nozzle section and, thus, can be repaired or replaced independently of the outer nozzle section.

First claim

What is claimed is:

1. A device for texturizing a strand material, the device comprising:
a nozzle body;
a locking device; and
a passage extending through said nozzle body,
wherein said passage extends from a first end of the nozzle body to a second end of the nozzle body,
wherein said passage is sized to allow a strand material to pass therethrough,
wherein said locking device is operable to be selectively placed in one of a first state and a second state,
wherein said first state corresponds to said locking device being engaged to prevent movement of said strand material within said passage,
wherein said second state corresponds to said locking device being disengaged to allow movement of said strand material within said passage,
wherein said locking device includes a piston and a spring disposed within a cavity,
wherein a seal holder is disposed within said cavity to fix a sealing member within said cavity, and
wherein said sealing member at least partially prevents debris from entering said cavity from said passage.

2. The device of claim 1 , wherein said sealing member is an O-ring.

3. The device of claim 1 , wherein said locking device is placed in said first state by commencing application of a pressurized fluid to said locking device.

4. The device of claim 3 , wherein said pressurized fluid is compressed air.

5. The device of claim 1 , wherein said locking device is placed in said second state by halting application of a pressurized fluid to said locking device.

6. The device of claim 5 , wherein said pressurized fluid is compressed air.

7. The device of claim 1 , wherein said cavity is formed in said nozzle body.

8. The device of claim 1 , further comprising a cutting device, wherein said cutting device is operable to sever said strand material.

9. The device of claim 1 , further comprising an outlet tube, wherein said outlet tube is removably attached to said nozzle body, and wherein said strand material is operable to pass through said passage and said outlet tube before exiting said outlet tube as a texturized material.

10. The device of claim 9 , wherein said outlet tube is harder than said nozzle body.

11. The device of claim 9 , wherein said outlet tube is secured to said nozzle body by a set screw.

12. The device of claim 1 , further comprising:
an outlet tube removably attached to said nozzle body,
wherein said passage extends through said nozzle body to said outlet tube,
wherein said first state corresponds to said locking device being engaged to prevent movement of said strand material within said passage and said outlet tube,
wherein said second state corresponds to said locking device being disengaged to allow movement of said strand material within said passage and said outlet tube,
wherein said strand material is operable to pass through said passage and said outlet tube before exiting said outlet tube as a texturized material, and
wherein said outlet tube is harder than said nozzle body.

13. The device of claim 12 , wherein said outlet tube is secured to said nozzle body by a set screw.
