Abstract:
An on-machine-seamable press fabric for the press section of a paper machine, said press fabric comprising:a system of first machine-direction (MD) yarns, a system of second machine-direction (MD) yarns, and at least one system of cross-machine-direction (CD) yarns, said at least one system of CD yarns being interwoven with said systems of first and second MD yarns to form an integrally woven multi-layered structure in a rectangular shape with a length, a width, two lengthwise edges and two widthwise edges, said first and second MD yarns forming first and second seaming loops, respectively, along each of said two widthwise edges thereof;a first seaming spiral attached to at least one of said first and second seaming loops at one of said two widthwise edges of said press fabric by a first pintle;a second seaming spiral attached to at least one of said first and second seaming loops at the other of said two widthwise edges of said press fabric by a second pintle,whereby said press fabric is joined into endless form during installation on the press section of a paper machine by interdigitating the coils of said first and second seaming spirals and by directing a third pintle through the passage defined by the interdigitated coils of said first and second seaming spirals.
