Abstract

An article of footwear and a variety of other products may incorporate a knitted component. An inlaid strand extends through the knitted component. A combination feeder may be utilized to inlay the strand within the 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.

Claims

1. A method of knitting comprising:

providing a knitting machine having a first feeder that dispenses a yarn, a second feeder that dispenses a strand, and a needle bed that includes a plurality of needles;

positioning a dispensing tip of the second feeder below an elevation of a dispensing tip of the first feeder;

moving the first feeder and the second feeder along the needle bed to (a) form a first portion of a course of the knitted component from the yarn and (b) inlay the strand into the first portion of the course;

positioning the dispensing tip of the second feeder at the elevation of the dispensing tip of the first feeder;

moving at least the second feeder along the needle bed to form a second portion of the course from the strand; and

wherein the first portion of the course and the second portion of the course form a continuous course of the knitted component.

2. The method recited in claim 1, wherein the first portion and the second portion form a first course of the knitted component;

and

the method further comprising manipulating the yarn with the plurality of needles to form a second course of the knitted component that is adjacent to and joined with the first course.

3. The method recited in claim 1, further including a step of reciprocating a position of the dispensing tip of the second feeder in a vertical direction.

4. The method recited in claim 1, further including a step of reciprocating a position of the dispensing tip of the second feeder between an extended position that is on one side of an area where the plurality of needles cross each other to a retracted position that is on an opposite side of the area where the plurality of needles cross each other.

5. The method recited in claim 4, wherein the extended position is located below the elevation of the dispensing tip of the first feeder;

and

wherein the retracted position is located at or above the elevation of the dispensing tip of the first feeder.

6. The method recited in claim 5, wherein the step of providing the knitting machine further includes locating a first portion of the plurality of needles on a first plane and locating a second portion of the plurality of needles on a second plane, the plurality of needles being movable from a first position to a second position, the plurality of needles being spaced from an intersection of the first plane and the second plane when in the first position, and the plurality of needles passing through the intersection of the first plane and the second plane when in the second position.

7. The method recited in claim 6, further including steps of (a) selecting the retracted position to be above the intersection of the first plane and the second plane and (b) selecting the extended position to be below the intersection of the first plane and the second plane.

8. The method recited in claim 1, further including a step of locating the second feeder in front of the first feeder while inlaying the strand into the first portion of the course.

9. The method recited in claim 1, further comprising:

utilizing the first feeder to knit, tuck, or float the yarn; and

utilizing the second feeder to knit, tuck, float, or inlay the strand.

10. A method of knitting comprising:

providing a knitting machine having;

(a) 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,

(b) a first feeder that is movable along the needle bed, the first feeder including a first feeder arm with a first dispensing tip for supplying a first yarn, the first dispensing tip being located above the intersection of the first plane and the second plane, and

(c) a second feeder that is movable along the needle bed, the second feeder including a second feeder arm with a second dispensing tip for supplying a second yarn, the second dispensing tip being movable from a retracted position that is located above the intersection of the first plane and the second plane to an extended position that is located below the intersection of the first plane and the second plane;

forming a first portion of a first course of a knitted component by (a) moving the first feeder along the needle bed and in a direction that is parallel to the intersection of the first plane and the second plane, (b) manipulating the first yarn with the needles to form a plurality of first loops in the first yarn, (c) placing the second dispensing tip in the extended position, (d) moving the second feeder along the needle bed and in a direction that is parallel to the intersection of the first plane and the second plane, and (e) inlaying the second yarn within the plurality of first loops in the first yarn; and

forming a second portion of the first course of the knitted component by (a) placing the second dispensing tip in the retracted position, (b) moving the second feeder along the needle bed and in the direction that is parallel to the intersection of the first plane and the second plane, and (c) manipulating the second yarn with the needles to form a plurality of second loops in the second yarn, the second loops being intermeshed with the first loops.

11. The method recited in claim 10, further including a step of locating the second feeder in front of the first feeder during the step of forming the first portion of the first course.

12. The method recited in claim 10, wherein the first portion of the first course and the second portion of the first course form a continuous course of the knitted component.

13. The method recited in claim 10, further comprising manipulating the first yarn with the plurality of needles to form a second course of the knitted component that is adjacent to and joined with the first course.

14. The method recited in claim 13, wherein the step of manipulating the first yarn to form the second course comprises (a) placing the second dispensing tip in the retracted position, (b) moving the first feeder along the needle bed and in a direction that is parallel to the intersection of the first plane and the second plane, and (c) manipulating the first yarn with the needles to form a plurality of third loops in the first yarn;

and

wherein the plurality of third loops are intermeshed with the plurality of first loops and the plurality of second loops of the knitted component.

15. The method recited in claim 10, further comprising:

utilizing the first feeder to knit, tuck, or float the first yarn; and

utilizing the second feeder to knit, tuck, float, or inlay the second yarn.

16. The method recited in claim 10, wherein the first yarn is a non-fusible yarn and the second yarn is a fusible yarn.

17. The method recited in claim 16, further including a step of heating the knitted component to bond the second yarn to the first yarn.

18. The method recited in claim 16, wherein the first yarn is entirely formed from at least one of a thermoset polymer material and natural fibers, and the second yarn is at least partially formed from a thermoplastic polymer material.

19. The method recited in claim 16, wherein the first yarn is substantially formed from thermoset polyester, and the second yarn is at least partially formed from a thermoplastic polyester.
