Abstract

A false twist texturing machine for the texturing of synthetic threads in one handling position at a time, in which a heating device and a false twist unit are disposed within a false twist zone. In an after-treatment zone are disposed a second heating device and a counter-twist apparatus. In this case a residual twist left in the thread from the false twist unit is removed by the counter-twist apparatus. The counter-twist apparatus is for this disposed in one plane with the second heating device, so that the thread is run substantially in a straight thread path.
