Title: METHOD AND DEVICE FOR PRODUCING TURF YARNS FOR ARTIFICIAL TURFS
Abstract:
The invention relates to a method and a device for producing turf yarns for artificial turfs. A plurality of monofilaments or strips are drawn together in the form of a fiber bundle after extruding a polymer melt and are stretched by multiple rollers. The fiber bundle is separated into a plurality of turf yarns with a respective group of strips or monofilaments and is crimped prior to being wound in order to form a coil. The aim of the invention is to allow a process which is as compact as possible. According to the invention, this is achieved in that the turf yarns are formed immediately after the stretching process and are crimped in a parallel manner next one another prior to being separated.
