Spindle start control device for textile yarn processing machine having knotting mechanism

In a textile yarn processing machine, such as a twister, spinning frame or the like, having a plurality of spindle assemblies positioned in side-by-side relationship thereon for processing of yarn, control means operatively connected with each of said spindle assemblies for selectively stopping and starting operation of said respective spindle assemblies, a yarn knotter mechanism for knotting together two ends of broken or otherwise separated yarn at selected spindle assembly locations in the event of a broken or otherwise separated yarn and including selectively actuatable means for operating said knotter mechanism for the knotting operation, holder means mounted on said yarn processing machine in front of each of said spindle assemblies for releasably receiving and mounting said yarn knotter mechanism at the desired knotting location in front of said selected spindle assemblies for a yarn knotting operation, and actuating means operatively connected with said respective control means and being responsive to reception and mounting of said yarn knotter mechanism in said respective holder means for actuating said control means to stop operation of said respective spindle assembly means for a yarn knotting operation;

• the improvement of:
• means operatively connected with said operating means of said knotting mechanism and said spindle stopping and starting control means and being responsive to actuation of said operating means of said knotter mechanism for actuating said control means to start operation of said spindle assembly for the processing of yarn, thereby reducing lost operating time due to yarn separation.

• the improvement of:
• means operatively connected to and being responsive to actuation of said operating means of said knotter mechanism for disengaging said switch actuating means and said switch means for actuating said control means to start operation of said spindle assembly for the processing of yarn, thereby reducing lost operating time due to yarn separation.
