Abstract:
A yarn processing apparatus comprisinga yarn processing device through which the yarn is advanced, a feed system for withdrawing the advancing yarn from the processing device and conveying the yarn along a normal path of travel to a takeup device, a yarn conveying nozzle located along the normal path of travel between the feed system and the takeup device and comprising at least one nozzle bore for generating an air stream which engages the advancing yarn and which has a component of movement extending in the direction of the advancing yarn, so that the air stream generates a tension on the yarn upstream of the yarn conveying nozzle and causes slack to be formed in the advancing yarn between the yarn conveying nozzle and the takeup device, a free space located downstream of the yarn conveying nozzle and laterally to one side of the normal path of travel for receiving an accumulation of the slack in the advancing yarn caused by the air stream, and wherein said nozzle is oriented so that the air stream has a directional component which acts to laterally deflect the advancing yarn from its normal path of travel and into the free space.
