Abstract: A textile machine for texturing textile yarns by false twisting, heating and cooling the false twisted yarns, has yarn feeding devices, a heating device with a heated surface, a cooling zone and a false twisting device. The feeding devices are operable to feed a yarn along a longitudinal yarn path in contact with the heated surface, through the cooling zone and the false twisting device. In such a machine, to provide that the surge speed is higher than would be the case with a conventional contact heater arrangement or guided non-contact heaters, to allow processing at these higher speeds without detriment to the yarn properties, and to minimize the temperature settings and hence the power consumption of the heater, the heated surface is substantially flat along the longitudinal yarn path, and the yarn path in the cooling zone extends in a direction different from that of the longitudinal yarn path.
