Abstract
A method for closing a seam in a paper processing belt having a coating of polymeric resin material requires the use of a viscous paste obtained by mixing a polymeric resin material with a blowing agent. Following installation of the fabric, or belt, on a paper machine by closing its pin seam with a pintle, the seam region on the non-paper side of the fabric or belt is impregnated with the viscous paste. The seam region is then heated to a temperature to activate the blowing agent and to create a foam from the paste. The foam fills voids in the seam region, and may pass out through the slit in the coating over the seam. Raising the temperature further cures the foam and may glue the slit closed. The belt so seamed may be used as a transfer belt or long nip press (LNP) belt, or in other paper processing applications.
