Abstract
Pieces of cloth are superimposed, with sewing fibers extending from themselves or separately placed on them. Fine jet streams of a liquid or a mixed fluid of gas and liquid under pressure are shot against the superimposed pieces of while moving the shooting position relative to the cloth. Then, the superimposed pieces of cloth are sewn together by the action of the jet streams that causes the sewing fibers to twine with the cloth. The jet streams are shot to the same point on the superimposed pieces of cloth from their both sides, thus causing the sewing fibers to twine with one another or with the superimposed pieces of cloth. At the same time, the resulting splashes of the sprayed fluid are sucked and removed from therearound. The jet streams acting on the sewing fibers from both sides cause them to sew together the superimposed pieces of cloth. The jet streams penetrating deep into the superimposed pieces of clotch collide with each other at high speed and vigorously splash about, accomplishing effective twining of the sewing fibers and leaving little liquid within the superimposed pieces of cloth. Most of the liquid splashes about and is removed from within surrounding covers through suction units.
