An improved papermakers' press felt and a method to make such an improved press felt, for use in papermaking, cellulose and similar machines, including a base fabric assembly joined without seaming. In one embodiment, the ends of the base fabric are joined to create an endless fabric by a needling operation that also entangles the batt into the base fabric. The ends to be joined to the flat-woven base fabric are preferably cut on a diagonal. To produce this fabric, a flat-woven base fabric is cut to the proper dimensions for a press felt and rolled into two continuous loops, one inside the other, to form the base fabric assembly. Alternatively, two flat-woven base fabrics of the appropriate size for a press felt are used. Each fabric is rolled once to form a loop and the two loops are assembled, one within the other, to form the base fabric assembly. In a second embodiment, the base fabric is joined prior to needling by a pintle cable inserted through loops formed when a void is formed in the fabric to accommodate the pintle cable. |
