Abstract

A combination feeder may be utilized to inlay a strand within a knitted component. As an example, the combination feeder may include a feeder arm that reciprocates between a retracted position and an extended position. In manufacturing the knitted component, the feeder inlays the strand when the feeder arm is in the extended position, and the strand is absent from the knitted component when the feeder arm is in the retracted position. A dispensing tip disposed at the end of the feeder arm supplies the strand for inlaying in a location disposed below the intersection of the planes of the needle beds and for one or more of knitting, tucking, and floating in a location disposed above the intersection of the planes of the needle beds.

First claim

What is claimed is:

1. A knitting machine comprising:
a needle bed that includes a plurality of needles, a first portion of the needles being located on a first plane, and a second portion of the needles being located on a second plane, the needles being movable from a first position to a second position, the needles being spaced from an intersection of the first plane and the second plane when in the first position, and the needles passing through the intersection of the first plane and the second plane when in the second position; and
at least one feeder that is movable along the needle bed, the feeder including a feeder arm with a dispensing tip for supplying a yarn, the dispensing tip being movable from a first location above the intersection of the first plane and the second plane for supplying the yarn for one or more of knitting, tucking, and floating to a second location below the intersection of the first plane and the second plane for inlaying the yarn.

2. The knitting machine recited in claim 1 , wherein the feeder arm is operable to reciprocate the dispensing tip between the first and second locations during a knitting process.

3. The knitting machine recited in claim 1 , wherein the feeder includes a carrier that joins the feeder to a rail of the knitting machine, the carrier being located above the intersection of the first plane and the second plane.

4. The knitting machine recited in claim 1 , wherein the first location is associated with a retracted position of the feeder arm.

5. The knitting machine recited in claim 4 , wherein the second location is associated with an extended position of the feeder arm.

6. The knitting machine recited in claim 1 , wherein the feeder arm is operable to reciprocate the dispensing tip through the intersection of the first plane and the second plane when moving between the first location and the second location.

7. The knitting machine recited in claim 1 , wherein the feeder includes at least one actuation area configured to induce movement in the feeder arm.

8. The knitting machine recited in claim 7 , wherein the at least one actuation area comprises an actuation arm; and
wherein a force upon the actuation arm moves the feeder arm from a retracted position to an extended position.

9. The knitting machine recited in claim 8 , wherein the first location is associated with the retracted position of the feeder arm; and
wherein the second location is associated with the extended position of the feeder arm.

10. The knitting machine recited in claim 7 , wherein the at least one actuation area comprises an electrical input coupled to a servomechanism.

11. A knitting machine comprising:
a needle bed that includes a plurality of needles, a first portion of the needles being located on a first plane, and a second portion of the needles being located on a second plane, the needles being movable from a first position to a second position, the needles being spaced from an intersection of the first plane and the second plane when in the first position, and the needles passing through the intersection of the first plane and the second plane when in the second position;
at least one rail extending above the needle bed; and at least one feeder that is movable along the at least one rail and the needle bed, the feeder including a feeder arm with a dispensing tip for supplying a yarn, the dispensing tip being movable from a first location above the intersection of the first plane and the second plane for supplying the yarn for one or more of knitting, tucking, and floating to a second location below the intersection of the first plane and the second plane for inlaying the yarn.

12. The knitting machine recited in claim 11 , wherein the feeder arm is operable to reciprocate the dispensing tip between the first and second locations during a knitting process.

13. The knitting machine recited in claim 11 , wherein the feeder includes a carrier that joins the feeder to the rail of the knitting machine, the carrier being located above the intersection of the first plane and the second plane.

14. The knitting machine recited in claim 11 , wherein the first location is associated with a retracted position of the feeder arm.

15. The knitting machine recited in claim 14 , wherein the second location is associated with an extended position of the feeder arm.

16. The knitting machine recited in claim 11 , wherein the feeder arm is operable to reciprocate the dispensing tip through the intersection of the first plane and the second plane when moving between the first location and the second location.

17. The knitting machine recited in claim 11 , wherein the feeder includes at least one actuation area configured to induce movement in the feeder arm.

18. The knitting machine recited in claim 17 , wherein the at least one actuation area comprises an actuation arm; and
wherein a force upon the actuation arm moves the feeder arm from a retracted position to an extended position.

19. The knitting machine recited in claim 18 , wherein the first location is associated with the retracted position of the feeder arm; and
wherein the second location is associated with the extended position of the feeder arm.

20. The knitting machine recited in claim 17 , wherein the at least one actuation area comprises an electrical input coupled to a servomechanism.
