Method for feeding in and starting a thread and false twist texturing device

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...

Problems solved by technology

Although this device works satisfactorily, its disadvantage is that once the yarn is broken, or to restart the fabric treatment, the end of the thread must be placed in the cylindrical object, which is a labor-intensive step because the yarn The thread has to be passed through a very small opening in the object in order to start the false twist deformation, which means that starting the device is very complicated and time-consuming
