The invention relates to a false twist texturing machine and to a method of texturing synthetic yarns in, in each case, one processing point, in which a twist-stopping device, a heating device, a cooling device and a false twisting unit are disposed inside a false twisting zone. The yarn is withdrawn from the false twisting zone by means of a delivery mechanism. According to the invention, the twist-stopping device takes the form of a rotatable transport roller, around which the yarn is at least partially wrapped in a peripheral direction and which is drivable by a drive in such a way that the yarn is braked or delivered, so that the yarn tensile force is adjustable inside the false twisting zone.

False twist texturizing machine

An apparatus and method for melt spinning a plurality of downwardly advancing multifilament polymeric yarns, and winding the advancing yarns into respective packages. Each of the advancing yarns is brought into contact with a separate yarn delivery mechanism which acts to control the yarn tension before the yarn is wound into a package. Thus, the yarn tension of all of the yarns can be made substantially the same when they are wound into packages, which permits all of the packages to have the same winding structure and the same packing density.

An apparatus for heating an advancing yarn is disclosed, which comprises an elongate heater body having a U-shaped channel accommodating a plurality of yarn guides. The yarn guides are configured and positioned such that the yarn advancing through the heating apparatus is deflected along a non-linear path of travel which includes several straight line segments which are closely adjacent and parallel to each of the side walls of the channel. The non-linear path effectively increases the yarn length in the heating apparatus, thereby facilitating high speed operation, and without unduly increasing the frictional resistance of the apparatus on the yarn.

Heating apparatus for an advancing yarn

A heating device for heating an advancing yarn, which has a groove in which the yarn advances along a zigzag line. To advance the yarn in the groove, yarn guides are provided, which are arranged spaced apart from each other on a common carrier so as to form a unitary structural unit. The structural unit is inserted on the bottom of the groove, and rests against the side walls of the groove. The yarn guides are configured as pins.
