<p>An improved papermakers' press felt includes a base fabric assembly joined without seaming. In one embodiment, the ends of the base fabric (15, 16) are joined (17, 17') to create an endless fabric by a needling operation that also entangles the batt (14) into the base fabric. The ends to be joined of the flat-woven base fabric are preferably cut on a diagonal. To produce this fabric, a flat-woven base fabric (15, 16) is cut proper dimensions for a press felt and rolled into two continuous loops, one inside the other, to form the 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 accomodate the pintle cable.</p> |
