  • Publication number: 20120139150
    Abstract: The invention relates to a method and a device for producing a grass yarn for artificial turf. A film is produced from a polymer material in an extrusion process and divided into individual strips. The strips are crimped before being coiled into spools. The aim of the invention is to achieve a structure which particularly matches natural grass. According to the invention, this is achieved in that the film or the strips are fibrillated by a needle roller before crimping and the strips are separated after on and individually crimped independently of each other.
