Patent ID: 6959738

Claim:
A method for tangling filaments of a weft yarn at least in a certain length section next to a leading end of said weft yarn for consolidating said filaments in the weft yarn on a loom with a pneumatic weft insertion and with at least one weft insertion nozzle pipe through which said weft yarn is driven in each weaving cycle for passing said weft yarn through a weft insertion channel of a reed in said loom, said method comprising the following steps: (a) first exposing, during a time duration between two consecutive weaving cycles, a first point or portion positioned along said length section of said weft yarn to a first air stream ( 19 ) having a first air pressure (P 1 ) and flowing in a first direction for holding said weft yarn stretched, (b) second exposing, within said time duration a second point or portion between said first point and said leading end of said weft yarn to a second air stream ( 20 ) having a second air pressure (P 2 ) higher than said first air pressure, and (c) causing said second air stream ( 20 ) to flow in a second direction that differs from said first direction, for tangling said filaments and thereby consolidate said filaments in said weft yarn.
