Abstract
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.
