Abstract
The invention relates to an artificial turf, comprising a backing and a number of artificial grass blades connected to the backing and extending transversely of the surface thereof, which artificial grass blades have an irregular, in particular a locally narrowed, cross-section. Owing to this locally narrowed cross-section in the vicinity of the free end thereof, these artificial grass blades greatly resemble natural blades of grass and also display similar behavior. The invention also relates to a method for forming such an artificial turf and to a device with which this method can be performed. The narrowed cross-section can herein be formed by stretching the artificial grass blades, wherein the artificial grass blades can be plasticized before, during and/or after the stretching, for instance by local heating thereof.
