process and apparatus for the formation of a double wire narrow down a suit

摘要

A method of weaving a fabric using, one at a time, two catch threads adjacent respectively a first edge warp and a second edge warp which are separated from the main weft by a pair of warp wires. The catch threads, edge warp and warp wires are moved or shedded in time sequence to cause one catch thread to be woven in the main warp and form exterior loops about its respective edge warp and the shuttle to form exterior loops about the opposite edge warp. The process is then reversed forming exterior loops using the second catch thread and the shuttle thread.
