A false-twist texturing machine of reduced height having along one side a series of vertical contact heating devices for yarns and on the other, or service side, wind-up devices for the treated yarn, is provided for each heating device with an individual thread guide channel enabling an operator to thread the heating device while he remains on the service side of the machine. The channel is tubular with a slot along its length. The operator attaches a weight to a thread emerging from a delivery device and puts it into an upper end of the channel inclined downwards above upper thread guide means to a vertical portion of the channel extending downwards past the remote side of the heating device to an inclined portion of the channel extending beneath further thread guide means to a point at which the weight emerges and is detached by the operator, who then threads it through a false-twist imparter and a delivery device on the service side to a wind-up device. Tension on the yarn causes it to emerge from the slot in the channel and make contact with the guide means and heating device. The vertical portion of the channel is hinged at one edge to the heating devices. Alternatively, the vertical portion of the channel may be mounted a little away from the heating device with intervening substantially parallel walls extending from the slot nearly to the heating device and between which the yarn passes from the channel to make contact with the heating device.

Threading device for a false-twist texturing machine without upper

A pneumatic auxiliary apparatus for introducing a running yarn into a false-twist texturing machine is described wherein two suction devices are arranged for attachment to perforated suction tubes extending along the machine and connected to a suction source. One such device has a suction nozzle connected by a pliable tube to a slide valve. This nozzle can be used to draw yarn through a tube leading from a false-twist imparter (associated with a heating plate) to a point where the yarn can be inserted into a delivery device that leads the yarn to the entry of a yarn guiding tube extending through a second heating device. The nozzle can then be mounted in a support at the said entry to enable the suction draw the yarn through the pliable tube to the slide valve. The valve is then closed and the valve is arranged so that, when being closed, it co-operates with a knife to sever the yarn. The second suction device is then applied to draw the yarn through the second heating device to a point where, on removal of the second heating device, it may be fed to a wind-up device.
