Abstract
The invention relates to a process for the insertion of a weft yarn in the shed of a weaving machine in which said weft yarn is drawn from a reserve located outside the shed to be inserted in the form of a loop of which one of the ends is fastened and the other thrown, wherein an air stream is blown in the shed in the direction of insertion of the weft, the speed of this air stream being less than or at the most equal to the speed of the thrown end, the action of this air stream being such that it tends to maintain the two ends of the loop separate from each other.
