摘要:
A method to produce a press felt for a fiber web producing and/or processing machine, including the steps of a) providing a load bearing base structure, which is, for example, produced of yarns, b) providing a first and a second non-woven fiber layer, c) imprinting a polymer material pattern onto the first or second non-woven fiber layer so that the polymer material pattern partially covers the layer, d) arranging the first non-woven fiber layer on one side of the base structure and e) arranging the second non-woven fiber layer on the first non-woven fiber layer in such a manner that the polymer material pattern is arranged between the two non-woven fiber layers. The present invention further relates to a press felt manufactured according to the method of the present invention.
