Zusammenfassung:1. Field of the Invention A method for manufacturing a press fabric for a paper machine includes the attachment of a strip of top laminate layer material to a base fabric using a heat-activated adhesive film. The top laminate layer material may be a woven fabric, a nonwoven mesh, or a thermoplastic sheet material, and, in any case, has the heat-activated adhesive film bonded to one of its two sides. The strip of top laminate layer material and heat-activated adhesive film together form a multi-component strip, which is spiralled onto the outer surface of the base fabric, with the side of the strip of top laminate layer material having the heat-activated adhesive film against the outer surface, in a closed helix, and bonded thereto with heat and pressure. The portions of the multi-component strip overhanging the lateral edges of the base fabric are then trimmed, and a staple fiber batt is needled into and through the top laminate layer formed by the multi-component strip to firmly attach it to the base fabric.
