ABSTRACT:
A yarn heating apparatus for use in a yarn false twisting machine, which has a heated axial channel in which the yarn advances along a zigzagged path. To guide the yarn in the axial channel, yarn guides are provided, which are mounted to a generally U-shaped sheet metal rail which is removably received in the axial channel. The U-shaped rail has a base and side strips which lie flat against the bottom wall and side walls of the channel, and the yarn guides are mounted to a rail by holding elements which include an opening in the rail and a projection on the yarn guides which extend through the opening so as to engage the wall of the channel. The yarn guides may be fabricated from a ceramic material, or include a ceramic coating.
