ABSTRACT:
In a widely-used type of ring, spinning or twisting machine, each spindle of the machine is provided at its upper end with a spinning head. This head is engaged by yarn to be wound onto a cop spool carried on the spindle, the yarn passing from the spinning head to the ring traveller associated with that spindle. Due to the engagement of the yarn with the spinning head it is generally not possible to employ known types of automatic cop removal device with such machines. To overcome this problem, cop-raising means are provided which, at the end of each cop-forming process and prior to operation of the cop-removal device, serve to raise the cop spools above the level of the upper ends of the spinning heads whereby to disengage the yarns therefrom. The cop-raising means comprise, for example, a mechanism arranged to displace upwardly the so-called ring nuts associated with each spindle.
