Heater rail designed to be economical - has double channels for yarn passing through at high speed formed from blocks of ceramic held on rail

A heater rail to heat a continuously passing yarn is composed of a number of identical blocks. These are placed on a support rail close together. The heater rail pref. has channels for the yarn, and guides at intervals along the rail. The blocks are identical beginning with the first block. These blocks may be held in a metallic rail, which may be straight, or curved, in which case the ends of the blocks are angled to fit closely together. The rail may provide a base for the blocks with an angled profile to fit into slots along the sides of the blocks or a plate at each side may fit into the slot. The rail may also be arranged to surround three sides of the blocks, and either turned over the top edge, or profiled near the top to enclose ridges in the blocks. This leaves the top open to thread the yarn into the double channels. ADVANTAGE - The rail is designed to be economical to produce and allows the yarn to pass through at an increased speed.

Cooling and loosening of yarn plug from jet texturing stuffer box

Synthetic yarn (1) is textured by driving it with a jet (13)into a stuffer box (3) or expansion chamber. The yarn plug (12) is then cooled by two rollers (40,41) rotating in opposite directions with the yarn plug (12) wrapped partially round them. The second roller (41) has a higher surface speed than the first roller (40). Pref. one or pref. both rollers (40,41) are hollow cooling drums with a perforated surface and internal suction so that cooling air flows radially inward. The yarn plug (12) forms wraps of 45 - 210 deg and internal baffles block the air flow from the parts of the periphery not covered by yarn. The drum surface has grooves to accept several yarn plugs in parallel. The surface speed of the rollers increases according to the relationship V2 = V2(1+D/R) where V1 and V2 are the surface speeds of the first and second roller resp., D is the yarn plug dia. and R the radius of the first roller (40).
