ABSTRACT:
The invention concerns a false-twist texturizing machine of the type in which the heater, the cooling zone and the false-twist spindle are in substantially straight alignment and arranged at least in part above the service zone. The machine of the invention is characterized by the fact that the heating device, arranged upstream of the spindle at the upper part of the machine, is an open heater and that the machine includes means for lacing up and guiding the yarn between the first yarn feeder and the entry point of the heating device. Such means may comprise a mobile launching device on a fixed ramp extending itself from proximate the first yarn feeder to a point proximate the heater entry, the aforesaid launching device being associated with a yarn deflecting element whose purpose is to distribute the twist communicated by the spindle in such a way that, when launching, the majority of the twist backs up to the level of the first yarn feeder and that, during normal operation, a minor part of the twist backs up to the first yarn feeder, the majority of the twist remaining in the heater.
