Abstract

A rolling guide for a fiber strand comprises a first support member extending from a base of the roller guide to a compound joint having first and second portions. The first portion of the compound joint is mounted on the first support member for rotation around a first axis. The second portion of the compound joint being rotatable relative to the first portion around a second axis at a compound angle to the first axis. A second support member is connected with the second portion of the compound joint at a proximal end of the second support member. A channeled roller is carried on the second support member distally from the proximal end, and mounted for rotation around a third axis. The channeled roller has an annular channel formed therein. A fastener is provided to selectively prevent the second portion of the compound joint from rotating around the second axis relative to the first portion of the compound joint. Also provided according to the present disclosure is a method of guiding one or more fiber strands from a fiber package on a creel device to a destination location for further processing.

Claims

1. A rolling guide for a fiber strand comprising:

a first support member extending from a base of the roller guide to a compound joint having first and second portions, the first portion of the compound joint being mounted on the first support member for rotation around a first axis;

the second portion of the compound joint being rotatable relative to the first portion around a second axis at a compound angle to the first axis;

a second support member connected with the second portion of the compound joint at a proximal end of the second support member;

a channeled roller carried on the second support member distally from the proximal end, and mounted for rotation around a third axis, the channeled roller having an annular channel formed therein;

a fastener positioned to selectively prevent the second portion of the compound joint from rotating around the second axis relative to the first portion of the compound joint.

2. A rolling guide for a fiber strand according to claim 1, wherein the first support member is operative to adjust the distance between the base of the roller guide and the compound joint.

3. A rolling guide for a fiber strand according to claim 1, wherein the position of the channeled roller is adjustable on the second support member relative to the second portion of the compound joint.

4. A rolling guide for a fiber strand according to claim 1, wherein the fastener is further operative to selectively prevent the first portion of the compound joint from rotating around the first axis.

5. A rolling guide for a fiber strand according to claim 1, wherein the first portion of the compound joint comprises a first facing surface, and the second portion of the compound joint has a second facing surface, the first and second facing surfaces opposing one another, at least one of the first or second facing surfaces is provided with one or more spaced, complementary, and interlocking surface features arranged radially around the second axis.

6. A rolling guide for a fiber strand according to claim 1, wherein the channeled roller comprises a plurality of channeled rollers, each channeled roller of the plurality mounted for rotation around the third axis independently of any other channeled roller in the plurality of channeled rollers, and each channeled roller of the plurality having an annular channel formed therein.

7. A method of guiding a fiber strand from a fiber package on a creel device to a destination location for further processing, the method comprising:

providing a roller guide according to claim 1;

placing the fiber strand in the annular channel of the channeled roller to turn the fiber strand from a first direction vector between the fiber package and the roller guide, to a second direction vector between the roller guide and the destination location;

orienting the channeled roller of the roller guide to place the fiber strand in a first plane defined by a bottom of the annular channel therein, the first plane containing both the first and second direction vectors, wherein the fiber strand is tangent to the annular channel; and

securing the fastener to hold the orientation of the channeled roller.

8. A method of guiding a fiber strand according to claim 7, further comprising holding the fiber strand under tension.

9. A method of guiding a plurality of fiber strands from respective origin locations on a creel device to respective destination locations for further processing, the method comprising:

providing a roller guide according to claim 6;

placing each of the plurality of fiber strands in a respective annular channel of the plurality of channeled rollers to turn the fiber strands from a first direction vector between the respective origin location and the roller guide, to a second direction vector between the roller guide and the respective destination locations, wherein no fiber strand crosses any other fiber strand;

orienting the roller guide to minimize a deviation of each fiber strand in the plurality from a respective plane defined by a bottom of its respective annular channel between the origin location and the channeled roller, and between the channeled roller and the destination location, wherein the fiber strand is tangent to the annular channel; and

securing the fastener to hold the orientation of the channeled roller.

10. A method of guiding a plurality of fiber strands according to claim 9, wherein more than one fiber strand share a channeled roller.

11. A method of guiding a plurality of fiber strands according to claim 9, further comprising holding the fiber strand under tension.
