APPARATUS FOR DISPLACEMENT MOTION CONTROL OF GUIDE BAR OF WARP KNITTING MACHINE

An arrangement can control displacement movement of a guide bar of a warp knitting machine or the like by means of a summation drive which, during the work cycle moves steering arrangements for underlap displacement and overlap displacement in a timely and appropriate manner. It comprises a first and a second overlap displacement control arrangement which operate in opposing directions and having a simultaneously operating underlap control arrangement, operating a switching mechanism which, upon choice, couples either the one or the other overlap control arrangement with the summing drive. If desired, there may be provided a third overlap displacement setting arrangement which is permanently coupled to the summation drive and optionally activated. In this manner, a variety of different overlap displacement patterns may be obtained with a lower switching frequency than once heretofore possible.
