Abstract
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 the processing of yarn, control devices operatively connected with each of the spindle assemblies for selectively stopping and starting operation of the respective spindle assemblies, and a yarn knotter mechanism for being selectively positioned in front of each spindle assembly in the event of a broken or otherwise separated yarn therein for knotting together the two ends of the separated yarn when the spindle is stopped by the control devices and including selectively actuatable mechanisms for operating the knotter mechanism for the knotting operation, the following improvement is provided. Mechanisms are operatively connected with the operating devices of the knotter mechanism and the spindle stopping and starting control mechanisms and are responsive to actuation of the operating devices of the knotter mechanism for actuating the control mechanisms to start operation of the spindle assembly for the processing of yarn, thereby reducing lost operating time due to the yarn separation.
