Abstract

A method of weaving a large-diameter seamless cylindrical fabric without piecing together a plurality of unit webs. The method comprises disposing a warp yarn as divided into a first group warp yarn, a second group warp yarn . . . ith group warp yarn . . . and an nth group warp yarn across the width of a weaving loom, inserting a weft in a zigzag fashion turning back at each loom end for each group in succession from the first group warp yarn to the nth group warp yarn and, then, again from the first group warp yarn to the nth group warp yarn to complete one cycle of weft insertion and repeating the same cycle a necessary number of times.

Claims

1. A method for weaving a large-diameter seamless cylindrical woven fabric on a loom comprising disposing a warp yarn from one group of warp yarns divided into first group yarns, second group yarns, ith group yarns and nth group yarns across the width of a weaving loom, inserting a weft yarn in a zigzag direction across said loom width in succeeding alternating opposite directions across each of said first group warp yarns to said nth group warp yarns completing one cycle of weft insertion and repeating the same cycle in the same order until said weaving of said seamless cylindrical woven fabric is completed.
