Abstract

The invention relates to a cooling device for synthetic threads, especially twisted threads in the deformation zone, said cooling device comprising an elongated heat sink with an open for guiding said thread Cooling grooves. The cooling groove is connected via a metering opening to a metering device for supplying cooling liquid. Due to the dynamic properties of the wires, in order to obtain uniform wetting and intensive cooling, the heat sink comprises at the wire inlet at least one ceramic insert forming corrugated grooves inside the cooling grooves bottom, and the wire can be guided in contact on the surface of the ceramic insert to which the metering opening is assigned. Thus, cooling liquid can be continuously supplied to the wire over longer distances.

Description

technical field [0001] The invention relates to a cooling device for synthetic threads, especially twisted threads in the deformation zone, said cooling device comprising an elongated heat sink with an open for guiding said thread A cooling groove connected via a metering opening in the bottom of the groove to a metering device for supplying cooling liquid. Background technique [0002] During the production of synthetic threads, it is known to crimp the multifilaments produced in the melt spinning process in a downstream process for textile purposes. In this way, the synthetic thread is given a structure similar to natural fibers. The further processing of the synthetic thread takes place by means of a texturing machine which has a plurality of processing stations in order to crimp a corresponding thread at each processing station. The crimping of the thread is also known as so-called "texturing" and can be achieved by so-called false twisting. Here, mechanical false twi...
