Abstract
Abstract Method of producing a weft knitted fabric on a rib knitting machine, and fabric produced thereby, at least a part of the fabric being a double fabric composed of two single fabrics. In the practice of the method, for the formation of connecting elements of the linking course of the double fabric, the corresponding stitches of one single fabric are formed on selected needles of one needle bed, and the corresponding stitches of the other single fabric are formed on selected second needles of a second needle bed, the second needles being opposite to the needles of the first needle bed inactive in this course, while for the laying of the sinker loops of both single fabrics in the same connecting element of the double fabric on one side of the same, a stitch of one single fabric is transferred on to the opposite needle of the other needle bed which needle is inactive in this course, on the active needle of which needle bed the stitch of the other fabric is immediately formed. In the process of knitting the stitches of the first single fabric on the active needles of the first needle bed the stitch of the other single fabric remains on the needle of the second needle bed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
A weft knitted fabric having at least one part thereof formed by a double fabric made up of two single fabrics, the double fabric comprising linking courses in which at one side of the double fabric there is at least one rib stitch of one single fabric a purl stitch of the other single fabric, and at the other side of said double fabric behind said purl stitch there is a sinker loop of said one single fabric and behind said rib stitch there is a sinker loop of said other single fabric, this arrangement of adjacent stitches and sinker loops forming an element connecting the two single fabrics.
Claim 2
Dependent Claim
109 words
A weft knitted fabric having at least one part thereof formed by a double fabric made up of two single fabrics, the double fabric comprising linking courses in which at one side of the double fabric there is at least one rib stitch of one single fabric a purl stitch of the other single fabric, and at the other side of said double fabric behind said purl stitch there is a sinker loop of said one single fabric and behind said rib stitch there is a sinker loop of said other single fabric, this arrangement of adjacent stitches and sinker loops forming an element connecting the two single fabrics.
Claim 3
Dependent Claim
75 words
A weft knitted fabric as claimed in claim 1, wherein the connecting elements are arranged side-by-side over the whole length of the linking course of the double fabric, so that in said linking course at one side of the double fabric at least one rib stitch of one single fabric and at least one pearl stitch of the other single fabric alternate, and at the other side sinker loops of the two single fabrics alternate.
Claim 4
Dependent Claim
20 words
A weft knitted fabric as claimed in claim 2, wherein every course of the double fabric is a linking course.
Claim 5
Dependent Claim
18 words
A weft knitted fabric as claimed in claim 1, wherein the single fabrics are of a jersey structure.
Claim 6
Dependent Claim
44 words
A weft knitted fabric as claimed in claim 1, wherein in each single fabric there is at least one pair of adjacent courses of which one course comprises rib stitches, and the other comprises pearl stitches at the same side of the single fabric.
Claim 7
Dependent Claim
19 words
A weft knitted fabric as claimed in claim 5, wherein the single fabrics are of a purl stitch pattern.
Claim 8
Dependent Claim
31 words
A weft knitted fabric as claimed in claim 1, wherein the sinker loops in all the linking courses are at the same side of the double fabric and form its back.
Claim 9
Dependent Claim
32 words
A weft knitted fabric as claimed in claim 1, comprising at least one pair of adjacent linking courses in which the sinker loops are disposed on opposite sides of the double fabric.
Claim 10
Dependent Claim
15 words
A weft knitted fabric as claimed in claim 1, wherein the fabric contains weft threads.
Claim 11
Independent Claim
269 words
A method of producing on a rib knitting machine a weft knitted fabric in which at least on part is formed by a double fabric made up of two single fabrics, the single fabrics being linked by connecting elements in linking courses wherein the connecting elements are formed of at least one rib stitch of one single fabric adjacent at least one purl stitch of the other single fabric at one side of said double fabric, and at the other side of said double fabric there is a sinker loop of said one single fabric behind said purl stitch and a sinker loop of said other single fabric behind said rib stitch, said method comprising forming said stitches of said one single fabric on selected active needles of one needle bed forming the corresponding stitches of said other single fabric on selected active needles of the second needle bed, which needles are opposite inactive needles of said first needle bed, while for laying the sinker loops of both single fabrics in the same connecting element of the double fabric on one side of the same said stitches of said one single fabric are transferred into the opposite inactive needles of said second needle bed, on the active needles of which the corresponding stitches of said other single fabric are formed immediately on the active needles of the second needle bed, while in the process of knitting the stitches of said first single fabric on the active needles of said first needle bed the stitches of said other single fabric remain on the active needles of said second needle bed.
Claim 12
Independent Claim
269 words
A method of producing on a rib knitting machine a weft knitted fabric in which at least on part is formed by a double fabric made up of two single fabrics, the single fabrics being linked by connecting elements in linking courses wherein the connecting elements are formed of at least one rib stitch of one single fabric adjacent at least one purl stitch of the other single fabric at one side of said double fabric, and at the other side of said double fabric there is a sinker loop of said one single fabric behind said purl stitch and a sinker loop of said other single fabric behind said rib stitch, said method comprising forming said stitches of said one single fabric on selected active needles of one needle bed forming the corresponding stitches of said other single fabric on selected active needles of the second needle bed, which needles are opposite inactive needles of said first needle bed, while for laying the sinker loops of both single fabrics in the same connecting element of the double fabric on one side of the same said stitches of said one single fabric are transferred into the opposite inactive needles of said second needle bed, on the active needles of which the corresponding stitches of said other single fabric are formed immediately on the active needles of the second needle bed, while in the process of knitting the stitches of said first single fabric on the active needles of said first needle bed the stitches of said other single fabric remain on the active needles of said second needle bed.
Claim 13
Dependent Claim
176 words
A method as claimed in claim 10, wherein to form the linking course containing the connecting elements only the course of one single fabric is formed on the selected active needles of one needle bed, and the corresponding course of the other single fabric is formed on the selected active needles of the other needle bed, which latter needles are opposite the needles, inactive in this course, of said first needle bed, while for laying the sinker loops of both single fabrics in the same linking course of the double fabric at one side of the same the stitches of said one single fabric are transferred on to the opposite neeDles, inactive in this course, of said other needle bed, on the active knitting needles of which the course of said other single fabric is formed immediately, while in the process of knitting the course of said first single fabric on the active needles of said first needle bed, the stitches of said other single fabric remain on the active needles of said second needle bed.

Claim 15
Dependent Claim
