Yarn twisting machine - with removable elastic coupling between the axially parallel and axially displaced assemblies

摘要

The mechanism for a yarn twisting machine has two assemblies rotating within each other, one having the same axis as the spindle and the other being axially displaced, with a flexible coupling to bond them together. The assembly on the spindle axis has a plate disc with a circular drilling in its base to accept a central circular core. Recesses in the plate disc and/or the core open into the drilling. The mounting units are attached either to the plate disc or the legs of the core defined between the recesses ranging towards the spool carrier. The axially displaced assembly rotates on an angled axis and is formed by >=1 tubular sleeves which shroud the spindle and are held by roller bearings in the fixed frame and the spool carrier. The tubular sleeve opens out in the middle and is fitted with sufficient recesses to match those of the first assembly, to give only sectors in the expanded zone in one of the recesses of the assembly matching the spindle axis. Further mountings are placed on these sectors arranged towards the spool carrier. The flexible coupling is a circular ring or polygonal ring with openings to take the various mountings for both assemblies. Arrangement gives the required flexible coupling between the two assemblies of the twister where the coupling can be removed easily for replacement without dismantling the equipment.
