Method for the manufacture of a nap mat having a rubber backing with nap free rubber edge zones, whereby the nap layer is fastened into a woven and/or non-woven primary texture which along with the nap layer is fastened to the upper side of an unvulcanized rubber backing by a press vulcanizing operation. Placing rubber strips in total or partial abutment against the underside of the rubber backing, before the press vulcanizing operation is initiated, so that said strips during the press vulcanizing operation are joint vulcanized with the rubber backing so that they form integrated parts thereof.
