Abstract
A yarn heating chamber is disclosed which comprises a rigid outer housing of U-shaped cross section and including transversely spaced apart side walls, and three plates mounted between the two side walls. A contact pressure gap is formed between the side walls and the adjacent surfaces of the two outer plates, and the central plate includes a yarn receiving groove on each of its outer surfaces. The central plate is laterally movable to a threading position wherein the grooves are exposed, and heating duct means is provided for introducing a hot pressurized vapor into the contact pressure gaps, to bias the two outer plates inwardly toward each other and thereby resiliently engage the central plate therebetween. The pressurized vapor is also conducted to each of the yarn receiving grooves.
