Abstract (en)
A loop-and-pintle seam in a paper-processing belt (72) having a polymeric-resin coating (68) is closed by covering the seam on the uncoated side with an encapsulating material, so that the seam area (50) has compression properties substantially identical to those of the remainder of the belt. After installing the belt (72) and closing the pin seam with a pintle (76), the seam region (50) is impregnated on the non-paper side with a viscous paste comprising a polymeric-resin material and a blowing agent. The paste is heated to create a foam that fills the voids in the seam region (50) and the slit (78) in the coating (68), before being cured. Alternatively, a solid foam strip (88) of a polymeric resin may be glued to the seam region (50). The belt may be used as a transfer or long-nip-press (LNP) belt. <MATH>
