摘要

Device for the compensation of the tension of the weft thread in winding units of a weaving device of weaving machines with a wave-like draft in the section comprised between the textile material and the winding units, which follow during the weaving process a trajectory endless, a sector, of which is common with the corresponding sector of a trajectory followed by frame insertion shuttles, whose compensation takes place after the separation of the winding unit and the insertion shuttle of the frame and after of the entrance of the shuttle of insertion of the weft in the shed, as well as after the incorporation of the weft yarn by weaving in the selvedge of the textile until the cutting of the weft yarn in the edge of the textile, being provided each winding unit of a gripper to block the removal of the weft yarn from the winding unit before separation, of the insertion shuttle the weft and the winding unit, characterized in that the winding device (7) is provided with control means for disconnecting chronologically adjustable the clamping function of the clamp (16) after the entrance of the shuttle (1) of insertion of the weft in the shed and after the incorporation of the weft yarn (6) by weaving in the selvedge of the textile (5).
