ABSTRACT:
A method and means for inserting the weft threads in a shuttleless weaving machine which are particularly advantageous. A weft thread reserve is formed between a selvedge of the fabric and the path of an inserting carrier, the weft thread is cut near the selvedge and pulled by the inserting carrier to the middle of the shed in the form of a loop having one arm constituted by the free end portion of the weft thread reserve and the other arm by the portion of weft thread connected to an outside weft, supply package, the apex of the thread loop in the inserting carrier is clamped by the nipper of a withdrawing carrier and pulled towards the other selvedge, the nipper of the withdrawing carrier opens when the same reaches a position distant from the other selvedge by an amount substantially equal to the length of the weft thread reserve, and the thread reserve is allowed to slide in the then open nipper of the withdrawing carrier so as to completely straighten as far as the other selvedge during the completion of the travel of the withdrawing carrier.
