Manufacturing processes of weaving 8

In a plain cloth, alternate warp threads are raised and the shuttle charged with a cop of weft, is passed across the loom, leaving a pick of yarn in place between the raised and unraised warp threads and at right angle to them. The raised threads are then lowered, the unraised threads simultaneously lifted and the shuttle returned in the reverse direction. The process is repeated continuously with the result that sucessive weft threads pass under and over each warp thread.
