PROCESSING OF MULTILAYER WEAVE DESIGN DATA

摘要

Technique for developing a multilayer weave design matrix from individual weave pattern matrices for the respective layers, the final matrix being in the form of binary operating instructions to a loom for actuating the warp threads in such a way as to provide the desired multilayer weave design. The individual layer matrices first are assembled into a block diagonal form of matrix in which these layer matrices are arranged as nonoverlapping, diagonally adjacent blocks, on one side of which (e.g., lower side) the large matrix is filled with bits of one value (e.g., 1's), while on the other side of the diagonal blocks (e.g., upper side) the large matrix is filled with bits of the opposite value (e.g., 0's). Row and column interleaving operations then are performed so that in the final matrix the rows and columns of each layer matrix are interspersed as evenly as possible with those of the other matrices. If interconnections between layers are desired, these are specified in the large matrix before its transformation, merely by changing the value of the 1 or 0 bit whose coordinates are the particular row of one layer and the particular column of the other layer which are to be interconnected or interlaced.
