Cutting elements for knitting machines

Claim 2

In a fabric knitting machine having in combination at least one needle reciprocating between a lowest and uppermost position defining a knitting cycle, means for guiding warp thread onto and about the needle with the upward thrust of the needle, means for urging a weft thread into position for knitting the warp thread about the weft thread in response to the reciprocating motion of the needle, and means for advancing the thus knitted fabric from the area of needle reciprocation at the completion of the knitting cycle, the improvement which comprises at least one cutting element for cutting the weft thread of the knitted fabric to a predetermined dimension, the element mounted on the knitting machine in a needle position for movement in unison with, but in spaced relationship to the needle, to cut the weft thread of the previous knitting cycle.

Claim 3

The fabric knitting machine according to claim 1 wherein the cutting element is a knife.

Claim 4

The fabric knitting machine according to claim 1 wherein there are a plurality of cutting elements.

Claim 5

A fabric cutting system for textile machinery comprising a fabric knitting machine having in combination at least one reciprocating needle for knitting the fabric, the reciprocation between a lowest and uppermost position defining a knitting cycle, and at least one cutting element for cutting the weft thread of the knitted fabric to a predetermined dimension, the cutting element mounted on the knitting machine in a needle position for movement in unison with but in spaced relationship to the needle, whereby the weft thread of the previous knitting cycle is cut by the cutter element.

Claim 6

A fabric cutting system for textile machinery comprising a fabric knitting machine having in combination at least one reciprocating needle for knitting the fabric, the reciprocation between a lowest and uppermost position defining a knitting cycle, and at least one cutting element for cutting the weft thread of the knitted fabric to a predetermined dimension, the cutting element mounted on the knitting machine in a needle position for movement in unison with but in spaced relationship to the needle, whereby the weft thread of the previous knitting cycle is cut by the cutter element.

Claim 7

A process for knitting fabric on a knitting machine which comprises reciprocating a needle between a lowest and uppermost position of a knitting cycle, guiding a warp thread onto and about the needle with the upward thrust of the needle, urging a weft thread into position for knitting the warp thread about the weft thread in response to the reciprocating motion of the needle to form a knitted fabric, advancing the thus knitted fabric from the area of needle reciprocation, and moving a cutting element in unison with the needle to cut the weft thread of the previous knitting cycle to a predetermined dimension.

Claim 8

A process for knitting fabric on a knitting machine which comprises reciprocating a needle between a lowest and uppermost position of a knitting cycle, guiding a warp thread onto and about the needle with the upward thrust of the needle, urging a weft thread into position for knitting the warp thread about the weft thread in response to the reciprocating motion of the needle to form a knitted fabric, advancing the thus knitted fabric from the area of needle reciprocation, and moving a cutting element in unison with the needle to cut the weft thread of the previous knitting cycle to a predetermined dimension.

Claim 9

A hollow fiber knitted mat cutting system for textile machinery, comprising a hollow fiber mat knitting machine having in combination at least one needle reciprocating between a lowest and uppermost position defining a knitting cycle, means for guiding warp thread onto and about the needle with the upward thrust of the needle, means for urging a hollow fiber into position for knitting the warp thread about the hollow fiber in response to the reciprocating motion of the needle, and means for advancing the thus knitted hollow fiber mat from the area of needle reciprocation at the completion of the knitting cycle, and at least one cutting element for cutting the hollow fiber of the knitted hollow fiber mat to a predetermined dimension, the element mounted on the knitting machine in a needle position for movement in unison with, but in spaced relationship to the needle, to cut the hollow fiber of the previous knitting cycle.

Claim 10

A hollow fiber knitted mat cutting system for textile machinery, comprising a hollow fiber mat knitting machine having in combination at least one needle reciprocating between a lowest and uppermost position defining a knitting cycle, means for guiding warp thread onto and about the needle with the upward thrust of the needle, means for urging a hollow fiber into position for knitting the warp thread about the hollow fiber in response to the reciprocating motion of the needle, and means for advancing the thus knitted hollow fiber mat from the area of needle reciprocation at the completion of the knitting cycle, and at least one cutting element for cutting the hollow fiber of the knitted hollow fiber mat to a predetermined dimension, the element mounted on the knitting machine in a needle position for movement in unison with, but in spaced relationship to the needle, to cut the hollow fiber of the previous knitting cycle.

Claim 11

The hollow fiber knotted mat cutting system of claim 6 wherein the cutting element is a knife.

Claim 12

The hollow fiber knitted mat cutting system of claim 6 wherein there are a plurality of cutting elements.

Claim 13

A process for knitting a hollow fiber mat on a knitting machine which comprises reciprocating a needle between a lowest and uppermost position of a knitting cycle, guiding a warp thread onto and about the needle with the upward thrust of the needle, urging a hollow fiber into position for knitting the warp thread about the hollow fiber in response to the reciprocating motion of the needle to form a hollow fiber mat, advancing the thus knitted hollow fiber mat from the area of needle reciprocation, and moving a cutting element in unison with the needle to cut the hollow fiber of the previous knitting cycle to a predetermined dimension.

Claim 14

A process for knitting a hollow fiber mat on a knitting machine which comprises reciprocating a needle between a lowest and uppermost position of a knitting cycle, guiding a warp thread onto and about the needle with the upward thrust of the needle, urging a hollow fiber into position for knitting the warp thread about the hollow fiber in response to the reciprocating motion of the needle to form a hollow fiber mat, advancing the thus knitted hollow fiber mat from the area of needle reciprocation, and moving a cutting element in unison with the needle to cut the hollow fiber of the previous knitting cycle to a predetermined dimension.
