Abstract
In a textile machine, a yarn heating arrangement incorporates a channel whose bottom surface is heated and a door which closes the channel and on whose inner surface are mounted yarn guides providing a yarn path adjacent the heated surface when the door is closed and the yarn guides are disposed within the channel. The length of the heated yarn path, or the proximity of the yarn to the heated bottom surface of the channel is adjustable to vary the level of heating of the yarn, and the door can be opened for cleaning and threading. A pivotal elongate yarn guide prior to the heater or pivotal elongate cooling track after the heater allow variation of the point of yarn inlet to or yarn outlet from the heater.
