The present application discloses a warp knitting traverse device and a warp knitting machine. The warp knitting traverse device includes a faceplate and a comb. The cross-section of the faceplate is an annular shape with different outer diameters, and the annular shape is divided into x number of equal parts, courses, along the circumferential direction and wherein 2≤x≤8; on the outer surface of the faceplate, at least two slopes are formed between adjacent courses. The present invention utilizes this new structural design, and designs a gradually gentle slope for buffering for the comb movement, allowing the comb to move step by step, which can avoid the instability caused by sudden large span, and is conducive to achieve high precision and smoothness in using a warp knitting machine in the process of fabric production. The new improvement preserve the machine for continuous production and achieve high throughput.

No: 17/981420 Application Filed: November 05, 2022 Assignees: Sumec Textile Technology Co., Ltd. (Nanjing, CN) Claim: 1-7. (canceled) Claim: 8. A double needle-bed warp knitting machine for knitting a plush fabric, comprising: a warp knitting shogging device, configured for knitting a plush fabric, comprised of core yarns and face yarns, having over 30% core yarns by weight in the plush fabric, comprising a first faceplate or a second faceplate, and a yarn guide assembly, wherein a cross section of the first faceplate is in an annular shape, wherein the cross section of the first faceplate has different outer diameters in different areas of the first faceplate, wherein the annular-shape cross section of the first faceplate is evenly divided into 8 sections along a circumferential direction of the annular-shape cross section, two slopes are formed between adjacent sections of the 8 sections; wherein a range of a push motion angle between adjacent sections of the 8 sections is 7.5° to 82.5°, and a pressure angle of any of the two slopes ranges from 15 to 35°; wherein the first faceplate is configured to knit the plush fabric having 30% core yarns by using the double needle-bed warp knitting machine according to steps of: N-N-N-N-N-N/0-0-0-0-0-0/(N−1)-(N−1)-(N−1)-(N−1)-(N−1)-(N−1)/0-0-0-0-0-0//or 0-0-0-N-N-N/N-N-N-0-0-0/0-0-0-(N−1)-(N−1)-(N−1)/(N−1)-(N−1)-(N−1)-0-0-0//or N-(N−1)-(N−1)-(N−1)-(N−1)-(N−1)/0-1-1-1-1-1// or 1-1-1-N-(N−1)-(N−1)/(N−1)-(N−1)-(N−1)-0-1-1//; wherein a cross section of the second faceplate is in an annular shape, wherein the cross section of the second faceplate has different outer diameters in different areas of the second faceplate, wherein the annular shape of the second faceplate is evenly divided into 6 sections along the circumferential direction, three slopes are formed between adjacent sections of the 6 sections; a range of a push motion angle between adjacent sections of the 6 sections is 7.5° to 82.5°, a pressure angle of any slope of the three slopes ranges from 10 to 15°; the second faceplate is configured to knit the plush fabric with over 30% core yarns by using the double needle-bed warp knitting machine according to steps of: N-N-N-N-N-N-N-N/0-0-0-0-0-0-0-0/(N−1)-(N−1)-(N−1)-(N−1)-(N−1)-(N−1)-(N−1)-(N−1)/0-0-0-0-0-0-0-0// or 0-0-0-0-N-N-N-N/N-N-N-N-0-0-0-0/0-0-0-0-(N−1)-(N−1)-(N−1)-(N−1)/(N−1)-(N−1)-(N−1)-(N−1)-0-0-0-0//or N-(N−1)-(N−1)-(N−1)-(N−1)-(N−1)-(N−1)-(N−1)/0-1-1-1-1-1-1-1// or 1-1-1-1-N-(N−1)-(N−1)-(N−1)/(N−1)-(N−1)-(N−1)-(N−1)-0-1-1-1//; wherein N is a number of the core yarns in a unit area of the plush fabric and the core yarns that are arranged in parallel and cover a face yarn in the unit area formed by two consecutive horizontal loops and two consecutive vertical loops made by the face yarn of the plush fabric, and N≥9. Claim: 9. (canceled) Claim: 10. The double needle-bed warp knitting machine of claim 8, wherein a transition of any of the two slopes or three slopes is arc-shaped. Claim: 11. (canceled) Current International Class: 04; 04; 04
