Embodiment Construction

[0024] figure 1 and 2 An embodiment of the device according to the invention for producing monofilaments is shown schematically. figure 1 A general view of the embodiment is schematically shown in and, and figure 2 A partial view of the winding device and the winding device is schematically shown. The following description is directed to both figures, as long as no explicit reference is made to either of these figures.

[0025] figure 1 A general view of an embodiment of the device of the present invention is shown in . This embodiment has an extrusion device 1 for extruding thermoplastic material into a plurality of filaments. For this purpose, the extrusion device 1 has an extruder 2 and a spinneret 3 connected to the extruder 2 .

[0026] Downstream of the extruder, a plurality of processing units are provided for drawing the monofilaments or linking each of the plurality of monofilaments and winding them as a fiber bundle. In this exemplary embodiment, the first tr...

Abstract

The invention relates to an apparatus for producing monofilaments or ribbons which are guided in parallel through several treatment devices in an extrusion process. For this purpose, an extrusion device is connected downstream in several treatment device, wherein for guiding the monofilaments or ribbons at least one rod-shaped guide element is provided which has a contact surface for guiding the ribbons or monofilaments. In order to enable low-friction and wear-resistant guidance, in particular when using very elastic monofilaments or ribbons, the contact surface has a multiple coating comprising several coating materials that are applied in several single coatings, each with a different layer thicknesses, wherein the single coatings are formed in a sandwich-like manner on the contact surface.

Description

technical field [0001] The invention relates to a device for producing monofilaments or strips according to the preamble of claim 1 . Background technique [0002] Such a device is known, for example, from DE 10 2005 049 163 A1. [0003] The known device has an extrusion device and a plurality of processing devices for producing a plurality of strips from the extruded film. In particular, in order to avoid sticking to the heated surface due to individual breaks when guiding a bundle of strips through the heating device, the heated surface is provided with an anti-stick coating. [0004] Furthermore, it is known that such an anti-adhesive coating, for example made of Teflon, forms a contact surface for the particularly advantageous low-friction guidance of the filaments or strips. Especially when producing grass yarns with relatively high elasticity, it is desirable to use low-friction guide elements, and it is therefore also known to use guide elements with low-friction co...
