Abstract
Abstract Method of, and apparatus for, making a stitch-bonded fabric with thermoinsulating properties having sufficient strength in all directions, to make it possible to use said stitch-bonded fabric for outerwear. The fabric includes a base and transversely arranged weft threads and warp threads knitted through the base by a warp knitted weave. In the method of the invention for manufacturing the product a weft system is fed parallely into the operation point of the stitch-knitting machine together with a base, and at the said operation point the said weft system is knitted together by warp threads, thus being connected to the base. In the apparatus according to the present invention a separating bar is mounted at the operating point of the stitch-knitting machine between the bits bar and the supporting comb.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
106 words
A method of manufacturing a stitch-bonded fabric which includes a fibrous fleece base including transversely laid weft threads and warp threads knitted through the base by a warp knitting weave, comprising simultaneously conveying in parallel relationship but at different speeds to the operation point of a stitch-knitting machine, on the one hand, a system of weft threads and, on the other hand, a fibrous fleece base, and connecting said system of weft threads to the base at said operation point by bonding them with warp threads, the speed of feeding the system of weft threads being higher than the speed of feeding the fibrous fleece base.
Claim 2
Independent Claim
106 words

Claim 3
Independent Claim
137 words
A device for manufacturing a stitch-bonded fabric which includes a fibrous fleece including transversely laid weft threads and warp threads knitted through the base by a warp knitting weave, comprising a stitch-knitting machine, means for simultaneously conveying in parallel relationship but at different speeds to the operation point of the stitch-knitting machine, on the one hand, a system of weft threads and, on the other hand, a fibrous fleece base, the speed of feeding the system of weft threads being higher than the speed of feeding the fibrous fleece base, means for connecting said system of weft threads to said base at said operation point by bonding them with warp threads, a separating bar, and a supporting comb, all arranged at the operation point of the stitch-knitting machine, the separating bar being disposed between the two combs.
