Abstract

A false twist texturing apparatus for false twist texturing a plurality of synthetic yarns in a plurality of processing stations, which each comprise a plurality of feed roll systems, a primary heater, a cooling device, a false twist unit, a secondary heater, and a takeup device. For accommodating the takeup devices, a takeup module is provided, and a processing module is provided for accommodating the false twist units, with a doffing aisle being formed along the takeup module and a servicing aisle along the processing module. To realize a short yarn path, the processing module and the takeup module are joined to form a frame section arranged between the servicing aisle and the doffing aisle. In this arrangement, the yarn passage from the processing module to the takeup module is formed by the secondary heater which is horizontally oriented, so that the yarn is guided between the false twist unit and the takeup device on the frame section along a generally U-shaped path.
