ABSTRACT:
There are disclosed a selvage structure of a knit-woven fabric, and an apparatus for producing it. The knit-woven fabric is produced in a warp-knit structure from weft thread loops and comprises spaced apart stitch wales with warp thread groups disposed therebetween, the warp threads being interlaced with stitch connecting loops to form a weave. The selvage of such fabric consists of a weft thread and a marginal weft thread, and comprises a marginal wale built by mutually binding stitches from a weft thread, stitches from a marginal weft thread, and stitches from a lock thread.
The apparatus for carrying out the method comprises a knitting mechanism for building a warp-knit structure from loops of weft thread, unwound from a stationary supply, said knitting mechanism comprising, on the one hand, a system of lapping guides the lapping arms of which are reciprocatorily swingable in open shed from an intermediate start position to one of extreme lapping positions and back again, the lapping guides protruding permanently between warp threads of at least one of the two shed planes, and, on the other hand, a system of knitting needles with closable hooks, of which number corresponds to that of lapping guides, the knitting needle system being arranged across the fabric and mounted for reciprocation from a foremost start position in front of the beat-up plane of the fabric to an operating position in open shed and back again, in order to engage the weft threads being laid, at either side of the system of lapping guides an auxiliary lapping guide is arranged for laying the lock thread, into the marginal knitting needle, the operation of said auxiliary lapping guide being the same as that of the lapping guides.
