US 2026/0146390 A1 · METHOD FOR PRODUCING AN ARTIFICAL TURF

Abstract

An artificial turf is produced by providing a carrier material and fibers, each comprising 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 fibers to a heated rotating calendar roller; guiding the carrier material with the fibers over at least one sub-region of the surface of the calendar roller. The connected regions of the fibers and the bottom of the carrier material face the calendar roller. While guiding the carrier material with the fibers over the at least one sub-region of the surface of the calendar roller: transferring heat from the calendar roller to the carrier material with the fibers, fusing the connected regions of the fibers with the bottom of the carrier material to the artificial turf, and removing and cooling the artificial turf.
