<p>A method of joining the ends of papermakers fabric is disclosed wherein machine direction yarns (12) are fringed out at the fabric ends, yarn ends (16) being laid across a pinned plate (13), and yarn ends (20) being cut back so as partially to overlie the plate. Those yarns (16) which extend across the plate (13) are folded back to form loops (14) beyond the edge of the plate and a thermoplastics matrix material (17) is applied to the plate. The matrix material (17) is made fluid by heating and, on subsequent cooling, forms an apertured end to the fabric which presents side-by-side, outwardly extending loops (14). The loops (14) at the respective fabric ends may be interdigitated to receive a pintle wire, thus to bring the fabric into endless form. A variation of the method is disclosed wherein a reticulate, premoulded seam element is engaged with the pinned plate for attachment to machine direction yarns of the fabric on melting of the matrix material, the seam element including axially aligned tunnels at a free edge thereof for cooperation with similar formations at an opposed fabric end and to receive a pintle wire.</p> |
