ABSTRACT:
A false-twist crimping machine for processing filament yarn. The machine comprises a side frame having a bobbin located thereon for supplying the filament yarn to a delivery means for guiding the yarn to a heating zone. A middle frame carries a cooling zone which receives the yarn as it feeds from the heating zone. A false-twisting means receives the yarn as it feeds from the cooling zone and a take-off means supplies the yarn emitting from the false-twisting means to a winding device located at the middle frame. In assembly, the heating zone slopes at an oblique angle between the side frame and the middle frame and a height-adjustable yarn guide means is positioned at the angle formed between the heating zone and the cooling zone in a manner so that the yarn may run over it along a line substantially tangent from the outlet of the heating zone and along a line substantially tangent to the inlet of the cooling zone.
