Abstract

Apparatus for spooling the weft thread in shuttles, for looms with multiple weft insertion in the warp, which is placed next to the loom and works in conjunction with the shuttles, which have rotationally arranged bobbins and are downloadable in an endless insertion chain arranged to move in a closed circuit in an oval path, of which a straight part guides along the weaving line and one of its centers of curvature corresponds to the entry of the shuttles into the shed of the warp, while the second center of curvature corresponds to the exit of the shuttles from the warp shed, the apparatus comprising a guide for the endless insertion chain, which is configured as an arc around a center of curvature of the oval path of the endless insertion chain, on the fixed part of the apparatus, drive means that mesh with the endless insertion chain, drive means of the driving means, fixed to the stationary part of the apparatus, glueing heads arranged for closed-loop movement on top of the guide for the endless insertion chain, guiding means of the glueing heads working together with the stationary part of the apparatus, spooling elements arranged in a rotary way in the spooling heads and working together with the shuttles, their separation corresponding to the separation between the shuttles, and their axes of rotation being identical to the axes of rotation of the corresponding bobbins of the shuttles, in the course of their common travel in the apparatus, actuating mechanisms of the glued elements that are placed in the glued heads, means for actuating the mechanisms of actuation of the glued elements, starting means for operating the drive mechanisms of the spooling elements which are located in the spooling heads, means for the reciprocal approach of the spooling elements to the shuttle bobbins in the course of spooling, weft thread reserve arranged in the apparatus, clamp means to hold the weft thread in the passage from the bobbin heads from the bobbin bobbins to the bobbin without bobbin, placed on the bobbin heads, at least one scissors to cut the bobbin weft thread, a bridge arranged in the form of an arch in the stationary part of the apparatus, actuation means for the starting means, the clamps and the scissors, respectively, arranged on the bridge, characterized in that it further comprises an oval guide (5), configured in the stationary part of the apparatus above the guide (16 ) for the endless insertion chain (21), an endless support chain (10), arranged on the oval guide (5), on whose links they are placed s the spooling heads (30), a center (b ') of curvature of the oval path of the support chain (10) being found above the center (b) of curvature of the oval path of the insertion chain (21) without end of the arc guide (16), while the second center (a ') of curvature of the oval path of the endless chain of support (10) is above the interior space (55) of the oval path of the insertion chain (21) endless, and drive means that mesh with the endless support chain (10), connected with the drive means (14) of the drive means, which mesh with the insertion chain (21) endless.
