<p>A helical coil seam construction for joining the ends of a length of papermakers fabric into a continuous loop is disclosed using a pair of generally helical coils (8, 10) formed of a multifilament yarn (22) subjected to a stiffening treatment with that stiffened yarn being formed into a helical coil. A first such coil (8) is affixed to a first end of a length of papermakers fabric and a second coil (10), wound in the direction opposite to the winding of the first coil (8), is affixed to a second end of the fabric, opposed to the first end. Means (18) are provided for releasably joining the coils (8, 10) with the loops thereof in an interengaged relationship, whereby the ends of the fabric are releasably joined to form a continuous loop of the fabric.</p> |
