ABSTRACT:
The present invention relates to a method of and apparatus for inserting weft yarn in jet looms, in which the weft yarn is inserted by the action of an inserting fluid jet and entraining fluid jets. The weft yarn is projected by the inserting fluid jet into the carrying jet field made up of at least two opposite systems of entraining fluid jets disposed close to and in front of the reed of the loom; the weft yarn is discontinually supported inside the carrying jet field, and the carrying jet field is simultaneously stabilized by withdrawing a part of the fluid from the boundary layer of the jet field.
