This invention pertains to papermaking felts, methods of making such felts, methods of using the felts, and methods of making paper using such felts. A felt of the invention contains at least one substrate web having a fuse-bonded joint extending across the width of the felt. The joint is preferably formed by superposing, onto each other, end portions of a flat-woven substrate web element, with the end portions extending away from the ends in a common direction, and concurrently severing the ends from the end portions, and fuse bonding the end portions to each other, along a common cut line.
