ABSTRACT:
A warp knitting machine comprises a brake operative upon current interruption. The guide bars are displaced by an electrical setting motor as well as a control arrangement, which establishes the position of the guide bars in dependence upon the angular position of the main shaft. The control arrangement bases its control upon a predetermined displacement function relating the positions of the main shaft and guide bar. The setting motor and control arrangement are connected to a main power source via an intermediate circuit, which has at least one storage condenser. This machine allows for a rather rapid change of the lapping pattern and a continuance of controlled guide bar displacement right up to the standstill of the main shaft.
