<p>The invention relates to a transmission with front worm gear of inverted conicity in the weaving machine yarn beam. According to the invention, the transmission consists of a front worm gear of inverted conicity, where the worm wheel is integral with the yarn beam and the worm is rotated by a drive system which ensures the rotation under a preset angle upon each pick of the weft yarn, a frusto-conical worm (9) of inverted conicity and a worm wheel (8) having a frusto-conical configuration of inverted conicity and curved toothing providing the conditions for eliminating the play between the flanks at a minimal front gauge.</p> |
