Abstract (en)
A yarn heating arrangement disposed in a straight yarn path crimping zone of a yarn texturing machine (10) comprises a first heater (32) which is maintained at a temperature in excess of the yarn's (13) crimp setting temperature, and may be above the melting temperature of the yarn (13),and heats the yarn (13) rapidly by radiation to a temperature of between 85% and 98% of its crimp setting temperature, and a smoothing heater plate (31) contacted by the yarn and maintained at the crimp setting temperature in order to heat the yarn (13) to that temperature. The overall length of the two heaters (31, 32) is less than that of a conventional contact plate heater, but they provide equivalent yarn temperature control which is greater than that provided by a high temperature non-contact heater alone. The heaters (31,32) are located between a twist-stop (23) and a false-twisting device (17) of the texturing machine (10). <IMAGE>
