ABSTRACT:
An apparatus for heating an advancing yarn is disclosed, which comprises an elongate heater body having a U-shaped channel accommodating a plurality of yarn guides. The yarn guides are configured and positioned such that the yarn advancing through the heating apparatus is deflected along a non-linear path of travel which includes several straight line segments which are closely adjacent and parallel to each of the side walls of the channel. The non-linear path effectively increases the yarn length in the heating apparatus, thereby facilitating high speed operation, and without unduly increasing the frictional resistance of the apparatus on the yarn.
