A pot-spinning machine is equipped with a rewinding tube mounted on each yarn guide and with a central, common shogging drive of the yarn guides at one side of the machine. After a yarn break or similar interruption in spinning, in order to be able to initiate the rewinding operation immediately at the affected spinning station while simultaneously continuing the spinning process unchanged at the neighboring spinning stations, the shogging motion of the yarn guide is separated from the motion of the rewinding tube supported on the yarn guide, so that the rewinding tube is then moved only at the forward indexing speed of the yarn guide which is relatively slow compared with the shogging speed and which does not affect the rewinding of yarn onto the rewinding tube.
In a pot-spinning machine having a plurality of rotatable spinning pots, a corresponding plurality of elongate hollow yarn guides for delivering respective yarn strands into the spinning pots for centrifugal formation of yarn cakes therein, said yarn guides being driven into motion, the motion being a shogging motion axially relative to an axis about which the spinning pots revolve and a simultaneous forward indexing motion, and a yarn guide rail for carrying the yarn guides and imparting the motion collectively thereto, the improvement comprising:
A method of pot-spinning yarns comprising the steps of delivering a plurality of yarns through a corresponding plurality of tubular yarn guides into a plurality of spinning pots for centrifugal formation of yarn cakes therein, simultaneously imparting to the yarn guides a shogging motion axially relative to the spinning pots and a forward indexing motion superimposed on the shogging motion, supporting a corresponding plurality of rewinding tubes for rewinding of the yarn cakes thereonto from the spinning pots, such that the rewinding tubes are driven correspondingly and independently from the yarn guides each rewinding tube being supported for axial displacement relative to a respective yarn guide to initiate a yarn rewinding operation, the rewinding tubes being supported independently of the shogging motion of the yarn guides for preventing the yarn guides from undergoing the shogging motion during the yarn rewinding operation.
