Abstract
In a shed-forming system of a weaving loom the drive shaft thereof is driven by an independent motor with controlled variable input which will depend upon the weaving program, the current forces on the components of the shed-forming system and constant forces inherent in the shed-forming system operation and by a second input shaft which synchronizes the drive shaft with the principal drive shaft of the loom.
Claims5
A system for driving the shed-forming system in a weaving loom having a primary loom drive shaft and wherein the shed-forming system includes an input drive shaft, a controller for reading weaving input programs and thereby controlling the movement of components of a harness including a heddle dependent upon the weaving input programs and a detector for detecting the rotational position of the input drive shaft for inputting detected rotational information to the controller, the system for driving comprising, a motor for directly driving the input drive shaft at variable speeds, and a synchronization drive shaft for drivingly connecting the primary loom drive shaft to the input drive shaft whereby the input drive shaft is subject to drive inputs from both said motor and the primary loom drive shaft.
