Embodiment Construction

[0040] figure 1 It is a cross-sectional view of the heat exchanger 1. The heat exchanger 1 has a lower part 2 and an upper part 3, which can be separated from each other. A yarn inlet 4 and a yarn outlet 5 are provided between the lower part 2 and the upper part 3. In addition, there are a plurality of yarn channels 6 between the lower part 2 and the upper part 3, and each yarn channel always has two sectors. The components 7 and 8 are composed of the fan-shaped member 7 fixedly arranged in the lower part 2 of the heat exchanger, and the fan-shaped member 8 is movably arranged in the upper part 3 along the axis of the yarn passage 6. At the same time, the fan-shaped member 8 is supported by a spring 9 squeezes a surface of the upper part 3, that is, a surface of the fan-shaped member 7, so that the two are sealed to each other. The two fan-shaped members 7, 8 together form the yarn channel 6, the diameter of which is usually a few tenths of a millimeter. A sealing device / ring 10...

Abstract

The invention relates to a method for feeding in and starting a thread in a false twist texturing device. Said device has a heat exchanger (1) containing a fluid. Said heat exchanger has at least two yarn passages (4, 5, 6) which are provided for guiding the yarn through and for sealing the heat exchanger (1). Said yarn passages (4, 5, 6) are enlarged for introducing the yarn. Alternatively, the yarn is drawn through the yarn passages (4, 5, 6) by suction and/or blown through by means of an auxiliary airflow or pulled through by means of an awl. The heat exchanger (1) in the false twist texturing device pertaining to this method is divided along the direction of passage of the yarn and the parts (2, 3) for introducing the yarn into the heat exchanger can be removed from each other. Alternatively, an injector nozzle (37) is arranged before and/or after the individual yarn passages (4, 5, 6) on the yarn inlet (4) and/or on the yarn outlet (5) for guiding the yarn through the yarn passage.

Description

Technical field [0001] The present invention relates to a method for inserting yarn and starting a false twist texturing device, wherein the false twist texturing device (Falschdrall texturiereinrichtung) has a fluid-containing heat exchanger with at least two yarns for introducing the yarn and for sealing the heat exchanger. Set the yarn channel. In addition, the present invention also relates to a false twist texturing device, which has a fluid-containing heat exchanger with at least two yarn passages for introducing the yarn and for sealing the heat exchanger. Background technique [0002] European patent EP 0 624 208 B1 discloses a false twist texturing device equipped with a heat exchanger. The heat exchanger is used as a heater and a cooler in turn. When the yarn touches, the fluid is now placed in an object through which the fluid can flow. The object is basically cylindrical and has small holes through which the yarn can be put into and drawn out of the object. Heat excha...
