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.
Claims9
A warp knitting machine adapted to be connected to a main power source, comprising:
- at least one guide bar;
- a main shaft;
- an electrical main motor coupled to said main shaft for driving the shaft;
- braking means coupled to said main shaft for braking the shaft upon interruption of current to said electrical main motor;
- and
- at least one supplemental system for influencing delivery of threads, said supplemental system being commonly powered with said main motor by said main power source, said supplemental system comprising:
- (a) at least one electrical setting motor for displacing said guide bar,
- (b) a control arrangement coupled to said main shaft and said setting motor and responsive to the angular position of the main shaft for positioning said guide bar as determined by a predetermined displacement function correlating positions of said guide and said main shaft, and
- (c) an intermediate circuit having an energy storage device for replacing interrupted power from said main power source to keep said setting motor and said control arrangement powered at least temporarily.
