Abstract
A drive system for weaving machines includes normally coupled main and auxiliary drive shafts for at least the batten and heddles of the weaving machine, respectively, with the shafts driven by main and auxiliary drive motors at different speeds through appropriate speed reducers and couplings. The shafts are coupled together at one point by an adjustable coupling that is controllable remotely so as to permit fine adjustment between the relative angular positions of the main and auxiliary drive shafts and therefore between the batten and heddle positions. This system has particular application during weaving machine start-up after a weaving interruption; e.g., when a thread break occurs. Various embodiments are described.
