A heat setting apparatus feeding assembly can comprise a yarn package rack having a first side and an opposing second side. A plurality of yarn package engagement elements can be positioned on each of the first side and the second side of the yarn package rack. The yarn package rack can be configured to rotate about a pivotal axis to orient one of the first side or the second side toward a yarn package loading area and to orient the other of the first side and the second side toward a feed direction.

A creel safety latch includes an elongated pivot-control bar defining a longitudinal slot having first and second terminal ends. The slot is adapted for receiving a latch pin of a movable bobbin creel. A first pin catch is located proximate the first terminal end of the slot, such that sliding movement of the latch pin along the slot and beyond the first catch locates the latch pin in a first holding position directly adjacent the first terminal end of the slot. A second pin catch is located proximate the second terminal end of the slot, such that sliding movement of the latch pin along the slot and beyond the second catch locates the latch pin in a second holding position directly adjacent the second terminal end of the slot.

The present disclosure provides a twisting machine for automatic donning, including an outer yarn branch rail arranged at the middle position of the twisting machine, wherein the outer yarn branch rail is positioned above the twisting machine, so as to successively drive the outer yarn carrier assembly to deliver the outer yarn winding package by suspending; further including an inner yarn branch rail arranged at the both sides of the twisting machine, the inner yarn branch rail is positioned above the twisting machine, so as to successively drive the inner yarn carrier assembly to deliver the inner yarn winding package by suspending. The forementioned structure enables the outer yarn winding package and the inner yarn winding package to be delivered high-efficiently in large scale by suspending and conveying, so as to largely reduce the labor intensity of operators and greatly improve production efficiency.

A yarn creel assembly includes a vertical frame, a plurality of vertically spaced package holders, and a vertically disposed arcuate yarn guide. The package holders are mounted on the frame and adapted for carrying respective yarn packages, whereby a tail end of a first yarn package is attached to a head end of a second yarn package. The arcuate yarn guide extends between adjacent package holders, and is adapted for guiding a moving end of yarn drawn from an emptying first yarn package and transitioning to a full second yarn package.
