Concrete steps are following:
A. by the requirement of the varied in thickness of the three-dimensional prefab corresponding organization chart that draws;
B. design maximum heald frame number by the three-dimensional prefab maximum thickness, the heald frame number required according to varied in thickness revised the line domain;
When the setting of loom program, take following method: setting the warp thread period is that (the warp thread period of 1≤n＜N=layer fabric is m to the n layer fabric of m, usefulness (1), (2), (3), (4), (5) with the N layer fabric that the warp thread period is M: n ... (m＜M=representes m.The fabric warp thread period of N layer is M.With 1,2,3,4,5 ... M, m+1 ... M+ (M-m)-1, M represent.So when fabric when the N layer becomes the n layer, total quantity of warps does not become on the loom, but the warp thread in tissue circulation of fabric has reduced M-m, the fabric thickness attenuation, when mentioning heald frame, descend method according to this:
Note: [M/m]=A, then the warp thread period M root in the N layer fabric, mark is done the warp thread period m root of n layer fabric,
Be exactly:
