ABSTRACT:
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.
