Abstract

A knitted component may incorporate an inlaid strand. 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 feeder for a knitting machine, the feeder comprising:

a carrier that includes an attachment mechanism for securing the feeder to the knitting machine such that the carrier is configured to move along a first axis relative to the knitting machine; and

a feeder arm extending outward from the carrier, the feeder arm including a dispensing area for supplying a strand to the knitting machine, the dispensing area being spaced away from the carrier, the feeder arm being configured to move along a second axis between a retracted position and an extended position relative to the carrier, the second axis being substantially normal to the first axis, the dispensing area being closer to the carrier in the retracted position than in the extended position, and

wherein the dispensing area is fixed against rotation relative to the carrier about a third axis that is substantially normal to the first axis and the second axis.

2. The feeder recited in claim 1, further including an actuation area, a force upon the actuation area causing the feeder arm to translate from the retracted position to the extended position, and removing the force from the actuation area causing the feeder arm to translate from the extended position to the retracted position.

3. The feeder recited in claim 2, wherein the actuation area is a pair of actuation arms having an outside end and an inside end, the actuation arms being positioned to define a space between the inside ends.

4. The feeder recited in claim 1, wherein the dispensing area is an end region of the feeder arm.

24. The feeder recited in claim 1, wherein one of the feeder arm and the carrier includes a projection and the other of the feeder arm and the carrier includes a slot, wherein the projection is received within the slot, and wherein abutment between the projection and an edge of the slot fixes the feeder arm against rotation relative to the carrier about the third axis.

25. The feeder recited in claim 1, further comprising at least one actuation member that is coupled to the carrier and coupled to the feeder arm, the at least one actuation member including an input surface that is configured to receive an input force from the knitting machine to move the actuation member relative to the carrier, the at least one actuation member further including a cam surface that is operable to move the feeder arm from the retracted position to the extended position as a result of the input surface receiving the input force.

a feeder arm extending outward from the second side of the carrier, the feeder arm including a dispensing area for supplying a strand to the knitting machine, the feeder arm being coupled to the carrier and configured to move between a retracted position and an extended position along a second direction, the dispensing area being closer to the carrier in the retracted position than in the extended position, and

wherein the first end is configured to receive a first input force from the knitting machine to cause the carrier to move in the first direction, and wherein the second end is configured to receive a second input force to cause the feeder arm to move between the retracted position and the extended position.

6. The feeder recited in claim 5, wherein the actuation member is configured to move relative to the carrier along the first direction, wherein the second end is configured to cause the actuation member to move in the first direction when the second end receives the second input force, and wherein the second direction is perpendicular to the first direction.

7. The feeder recited in claim 5, wherein the dispensing area is an end region of the feeder arm.

27. The feeder recited in claim 5, wherein the second end is configured to receive the second input force to cause the feeder arm to move in the first direction and to retain the feeder arm in the extended position.

28. The feeder recited in claim 5, wherein the at least one actuation member is coupled to the carrier and coupled to the feeder arm, the at least one actuation member further including a cam surface that is operable to move the feeder arm from the retracted position to the extended position as a result of the input surface receiving the input force.

29. The feeder recited in claim 28, further comprising a projection that is coupled to the feeder arm, wherein the at least one actuation member includes a first actuation member with a first cam surface and a second actuation member with a second cam surface, the first actuation member being configured to move relative to the carrier to cause the first cam surface to engage the projection to move the feeder arm from the retracted position to the extended position, the second actuation member being movable relative to the carrier independently of the first actuation member and generally toward the first actuation member to cause the second cam surface to engage the projection to move the feeder arm from the retracted position to the extended position.

8. A feeder for a knitting machine, the feeder comprising:

a carrier that includes an attachment mechanism for securing the feeder to the knitting machine such that the carrier is configured to move in a first direction relative to the knitting machine, the carrier having a first side and an opposite second side;

a pair of actuation arms located at the first side of the carrier, each of the actuation arms having an outside end and an opposite inside end, the actuation arms being positioned to define a space between the inside ends; and

a feeder arm extending outward from the second side of the carrier, the feeder arm including a dispensing tip for supplying a strand to the knitting machine,

wherein a first input force from the knitting machine upon one of the inside ends and directed away from the space causes the carrier to move in the first direction relative to the knitting machine, and

wherein a second input force from the knitting machine upon one of the outside ends and directed toward the space causes the feeder arm to translate from a retracted position to an extended position, the dispensing tip being closer to the carrier in the retracted position than in the extended position.

9. The feeder recited in claim 8, wherein removal of the second input force upon one of the outside ends causes the feeder arm to translate from the extended position to the retracted position.
