Abstract
Abstract Apparatus is disclosed for bringing into proximity and connecting a quench stack and monomer ring for the melt spinning of synthetic polymer fibers. These members are brought into proximity through use of a reel assembly and are connected by means of a clamping device. The clamp, which is mounted on the quench stack, features a drawpiece comprising a rod. The rod is curved into a "U" shape, the base of which engages with a keeper element and the legs of which describe a circle bend prior to terminating in a threaded shank for mounting to the clamp.
