Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
In a circular knitting machine, a needle cylinder, needles mounted in the cylinder, a dial having a plurality of grooves corresponding to a number of longitudinal warp yarns to be bound into a knit fabric, a pair of hooked members slidable in each said groove, each said pair together defining an eyelet for the passage of a corresponding needle of the cylinder, one of the members acting as a guide for a longitudinal warp yarn whilst the other of the members as a step therein serving to retain the longitudinal warp yarn and the hooked members being resiliently separable to enable the transverse withdrawal of the members from a needle engaged in said eyelet, means, combined with the cylinder to supply the longitudinal warp yarn, and means to advance the two hooked members before the corresponding needle which is engaged in the eyelet is lifted and to cause the hooked members to retract before said needle has been lowered, said advancing means acting on the said two hooked members independently of adjacent hooked members.
Claim 2
Dependent Claim
174 words
In a circular knitting machine, a needle cylinder, needles mounted in the cylinder, a dial having a plurality of grooves corresponding to a number of longitudinal warp yarns to be bound into a knit fabric, a pair of hooked members slidable in each said groove, each said pair together defining an eyelet for the passage of a corresponding needle of the cylinder, one of the members acting as a guide for a longitudinal warp yarn whilst the other of the members as a step therein serving to retain the longitudinal warp yarn and the hooked members being resiliently separable to enable the transverse withdrawal of the members from a needle engaged in said eyelet, means, combined with the cylinder to supply the longitudinal warp yarn, and means to advance the two hooked members before the corresponding needle which is engaged in the eyelet is lifted and to cause the hooked members to retract before said needle has been lowered, said advancing means acting on the said two hooked members independently of adjacent hooked members.
Claim 3
Dependent Claim
47 words
A machine according to claim 1, wherein said dial carries radially movable needles arrayed between the hooked members, said radially movable needles being arranged to knit a second yarn independent of the yarn supplied to the needles of the cylinder and being controlled by said advancing means.
Claim 4
Dependent Claim
21 words
A machine according to claim 1, wherein there is a pair of hooked members corresponding to each needle of the cylinder.
Claim 5
Dependent Claim
36 words
A machine according to claim 1, further comprising means for feeding rearwardly of the cylinder needles a horizontal weft yarn, said means acting to feed the horizontal yarn before the needles of the cylinder are raised.
Claim 6
Dependent Claim
46 words
A machine according to claim 1, further comprising a fixed structure above the dial, a disc member arranged above the fixed structure, means for driving the needle cylinder, the dial and the disc member sychronously, and a plurality of bobbin container mounted on the disc member.
Claim 7
Independent Claim
103 words
A method of producing a knitted fabric, comprising the steps of: knitting a yarn to form a main knit fabric with longitudinally extending rows of stitches, each being associated with a transversely extending course of stitches; feeding a longitudinally extending warp yarn along each vertically extending row of stitches, binding the base of each stitch in each row by wrapping said warp yarn about same during the formation of the main knit fabric; feeding a transversely extending weft yarn along horizontal course of stitches; and engaging the weft yarn between the stitches of the course and the corresponding lengths of the warp yarn.
Claim 8
Independent Claim
103 words
A method of producing a knitted fabric, comprising the steps of: knitting a yarn to form a main knit fabric with longitudinally extending rows of stitches, each being associated with a transversely extending course of stitches; feeding a longitudinally extending warp yarn along each vertically extending row of stitches, binding the base of each stitch in each row by wrapping said warp yarn about same during the formation of the main knit fabric; feeding a transversely extending weft yarn along horizontal course of stitches; and engaging the weft yarn between the stitches of the course and the corresponding lengths of the warp yarn.
Claim 9
Dependent Claim
54 words
A method as claimed in claim 6, comprising the step of: feeding a further binding yarn to form stitches of a second knit fabric, said last-mentioned stitches being interlaced with the stitches of said main knit fabric and being arranged on the side opposite the main fabric stitches in respect of said weft yarns.
Claim 10
Independent Claim
73 words
A method of producing a knitted fabric, comprising the steps of: knitting a yarn to form a main knit fabric with longitudinally extending rows of stitches, each being associated with a transversely extending course of stitches; feeding a longitudinally extending warp yarn along each vertical row of stitches, and binding the base of the stitch in each row by wrapping said warp yarn about same during the formation of the main knit fabric.
Claim 11
Independent Claim
73 words
A method of producing a knitted fabric, comprising the steps of: knitting a yarn to form a main knit fabric with longitudinally extending rows of stitches, each being associated with a transversely extending course of stitches; feeding a longitudinally extending warp yarn along each vertical row of stitches, and binding the base of the stitch in each row by wrapping said warp yarn about same during the formation of the main knit fabric.
