Abstract
A yarn false twist texturing machine for texturing multifilament synthetic yarns (4), wherein a heating device and a false twist unit are arranged within a false twist zone. An aftertreatment zone accommodates a second heating device and a countertwist device. The countertwist device is used to remove any residual twist that is left in the yarn by the false twist unit. To be able to perform a selective treatment by the countertwist device, a first embodiment provides for a twist imparting member yarn guide means for guiding the yarn (4) and being adapted for reciprocal movement between an idle position for not treating the yarn (4) or for threading it and an operating position for treating the yarn (4). In a second embodiment, the countertwist device comprises a movable twist imparting member (28, 29), which is adapted for reciprocal movement between an idle position for not treating or for threading the yarn (4) and an operating position for treating the yarn (4) by twisting it.
