PURPOSE: To obtain seamless tubular woven fabric for base cloth of ink ribbon and belt conveyor required to have high uniformity by inserting dummy warp between warps at both selvedge regions having warp density lower than the main fabric and carrying out the weaving operation.

CONSTITUTION: Multifilaments of polyester or nylon are used as warps 1 and wefts 2 to weave seamless tubular fabric by hollow weaving. In the above process, the density of warps 1 is adjusted to be coarser at both selvedge regions A, A than at the main fabric region B. A dummy warp 1' made of high-strength stainless steel fiber, aromatic polyamide fiber, etc., is inserted between the coarsely arranged warps 1 of both selvedge regions A, A and is subjected to fold weaving. The dummy warp is fixed at the upstream side and freed at the downstream side to a proper position beyond the cloth fell down to a breast beam. The dummy warp 1' is pulled out of the woven fabric 8 as the weaving progresses to obtain uniform seamless tubular woven fabric free from the warp density difference between the selvedge regions A, A and the main fabric region B.
