Abstract
The invention relates to a texturing device (1) for texturing at least one continuous yarn consisting of a plurality of filaments. This texturing device (1) has at least one housing (10) and at least one nozzle core (20), which can be charged with a fluid. The nozzle core (20) includes a yarn channel (21) and at least one fluid feed channel (22), opening into the yarn channel with a radial component. Furthermore, the nozzle core (20) includes an outlet region (23) of the yarn channel (21) and an inlet region (24) with an inlet opening (25) of the yarn channel (21). The distance between the inlet opening (25) of the inlet region (24) and the fluid feed channel (22) of the nozzle core (20) opening into the yarn channel (21) is at most 12.5 mm. The region (11), which is located ahead of the inlet region (24) of the nozzle core (20) in the direction of filament movement, has a radial outer delimiting area (12). This lies outside a cone of 20° narrowing in the direction of filament movement. The outer delimiting area (12) preferably lies outside a cone of 30°.
