Combination feeder for a knitting machine
A knitting machine with multiple feeders may be utilized to knit a knitted component. Feeders may be used to knit the knitted component and a combination feeder may also inlay an inlaid strand within the knitted component. As an example, a combination feeder may include a feeder arm that reciprocates between a retracted position and an extended position. In manufacturing the knitted component, a 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.
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
a plurality of feeders that are movable along the needle bed, each feeder of the plurality of feeders including an actuation member coupled to 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, wherein the actuation member is configured receive an input force and to move in response to the input force, and wherein the movement of the actuation member causes the movement of the dispensing tip between the first location and the second location.
2. The knitting machine recited in claim 1 , wherein the plurality of feeders comprises more than two feeders.
3. The knitting machine recited in claim 2 , wherein the plurality of feeders comprises at least four feeders.
4. The knitting machine recited in claim 1 , wherein the knitting machine further comprises at least one rail extending above the needle bed.
5. The knitting machine recited in claim 4 , wherein each feeder of the plurality of feeders includes a carrier that joins the feeder to the at least one rail.
6. The knitting machine recited in claim 4 , wherein the plurality of feeders comprises two feeders, and wherein the two feeders are joined to the at least one rail on opposite sides of the same rail.
7. The knitting machine recited in claim 4 , wherein the knitting machine comprises a plurality of rails extending above the needle bed.
8. The knitting machine recited in claim 7 , wherein each rail of the plurality of rails includes multiple feeders of the plurality of feeders.
9. The knitting machine recited in claim 1 , wherein each actuation member of the plurality of feeders includes at least one actuation area configured to receive the input force.
10. The knitting machine recited in claim 9 ,
wherein the at least one actuation area comprises an actuation arm; and
wherein the input force acting upon the actuation arm causes the feeder arm to move from a retracted position to an extended position.
11. The knitting machine recited in claim 9 , wherein the at least one actuation area comprises an electrical input coupled to a servomechanism.
12. The knitting machine recited in claim 1 , wherein the dispensing tip is configured to supply any one of more of a filament, a thread, a rope, webbing, a cable, a chain, and the yarn for inlaying at the second location.
13. 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.
14. 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;
a plurality of rails extending above the needle bed; and
a plurality of feeders that are movable along one or more of the plurality of rails and the needle bed, each feeder of the plurality of feeders including an actuation member coupled to 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, wherein the actuation member is configured receive an input force and to move in response to the input force, and wherein the movement of the actuation member causes the movement of the dispensing tip between the first location and the second location.
15. The knitting machine recited in claim 14 , wherein each rail of the plurality of rails includes one or more feeders of the plurality of feeders.
16. The knitting machine recited in claim 14 , wherein each feeder of the plurality of feeders includes a carrier that joins the feeder to one rail of the plurality of rails.
17. The knitting machine recited in claim 14 , wherein each rail of the plurality of rails includes at least one feeder of the plurality of feeders on each side of the rail.
18. The knitting machine recited in claim 14 , wherein the plurality of feeders includes at least one conventional feeder that is configured to move along at least one rail of the plurality of rails and the needle bed, the at least one conventional feeder including a dispensing tip for supplying a yarn, the dispensing tip being located above the intersection of the first plane and the second plane for supplying the yarn for one or more of knitting, tucking, and floating.
19. The knitting machine recited in claim 14 , wherein each actuation member of the plurality of feeders includes at least one actuation area configured to receive the input force.
20. The knitting machine recited in claim 19 ,
wherein the at least one actuation area comprises an actuation arm; and
wherein the input force acting upon the actuation arm causes the feeder arm to move from a retracted position to an extended position.
21. The knitting machine recited in claim 19 , wherein the at least one actuation area comprises an electrical input coupled to a servomechanism.
22. The knitting machine recited in claim 14 , wherein the feeder arm of each feeder of the plurality of feeders is operable to reciprocate the dispensing tip between the first and second locations during a knitting process.
