Abstract

The invention relates to method for producing an artificial turf, comprising the following steps: providing a carrier material having a top and a bottom, providing a plurality of fibres, wherein each fibre comprises two ends extending from the top of the carrier material and comprising a connected region arranged in a loop-like manner at the bottom of the carrier material; feeding the carrier material with the fibres to a heated rotating calender roller; guiding the carrier material with the fibres over at least one sub-region of the surface of the heated rotating calender roller, wherein the connected regions of the fibres and the bottom of the carrier material face the calender roller; during the guiding of the carrier material with the fibres over the at least one sub-region of the surface of the heated rotating calender roller: transferring heat from the heated rotating calender roller to the carrier material with the fibres, and fusing the connected regions of the fibres with the bottom of the carrier material to the artificial turf, and removing and cooling the artificial turf. The invention further relates to an artificial turf comprising: a carrier material having a top and a bottom; a plurality of fibres, wherein each fibre comprises two ends extending from the top of the carrier material and comprising a connected region arranged in a loop-like manner at the bottom of the carrier material, wherein the carrier material is fused at the bottom to the connected regions of the fibres.
