Abstract
A texturing apparatus for draw texturing a synthetic yarn. To this end, the texturing machine comprises a first feed system, a heating device, a cooling device, a texturing unit, a second feed system, and a takeup device for winding the textured yarn. Between the heating device and the cooling device, a wetting device is provided for wetting the heated yarn with a cooling fluid for purposes of precooling. The wetting device consists of a rotatable cooling cylinder which includes on its circumference a yarn track that contains a cooling fluid. The yarn can be wetted by contacting the yarn track. At the point of contact, the yarn friction is advantageously dependent on the relative speed between the yarn and the yarn track on the circumference of the cooling cylinder.
