A press blanket for a pressing device intended for extracting water from a web in the press nip of a papermaking machine comprises an elastomeric matrix, in which the outer area, facing the web, is subjected to a thermal treatment in order to increase the wear-resistance. Although the elastomeric matrix thus consists of the same material throughout, the outer area, which is subjected to greater stresses, therefore exhibits increased wear-resistance. The press blanket is made in a single operation, by casting a hot-casting elastomeric matrix onto a cylindrical casting mold, while at the same time reinforcing threads are wound into the material. The press blanket is selectively thermally treated in order to achieve increased wear-resistance at the outer surface facing the web.
