Abstract
A knitted fabric formed on a knitting machine includes longitudinal and transverse weft yarns incorporated into the fabric during knitting. A further transverse weft yarn is incorporated into the fabric and is interlinked with the courses of stitches of the fabric. Part of this further yarn, as determined by the needle selection, is visible on a surface of the fabric and serves to provide a pattern effect.
Claims5
A process for forming a fabric using a knitting machine having needles, said process comprising knitting on the machine a fabric having courses of interlinked stitches, incorporating longitudinal and first transverse weft yarns in the fabric, incorporating a further transverse weft yarn in the fabric, said further transverse weft yarn being interlinked with the zones of the fabric in which the stitches of one course of knitted stitches are interlinked with those of an adjacent course, and providing a needle selection such that the further weft yarn appears in selected parts of the surface of the fabric.
In a knitting machine,
- an array of slidable needles,
- sinkers cooperating with said needles,
- means operative to feed longitudinal weft yarns between contiguous needles,
- yarn guide means for at least one stitch yarn,
- yarn guide means for a first transverse weft yarn in correspondence with each feed in front of the needles,
- yarn guide means for a further weft yarn downstream of said guide means for said first transverse weft yarn,
- feed means operative to feed the stitch yarn from behind the needles and present the same at the front of the needles,
- first and second sinkers in correspondence with each interspace between contiguous needles, and
- means for actuating said sinkers separately, said actuating means comprising,
- means for advancing the first sinker to move the further transverse weft yarn behind the needles before the raising thereof, and
- means for advancing the second sinker after an at least partial raising of the needles, to bring said further yarn behind the needles which have not been raised and against the raised needles, the stitches being formed after raising of all the needles or further needles.
