SEAM FOR MULTIAXIAL PAPERMAKING FABRICS
Application 1321/MUMNP/2006 published 2007-04-13, filed 2006-11-09
A method of seaming an on-machine-seamable multiaxial papermakerâ™s fabric to prevent yarn migration. The multiaxial fabric (22) is in the form of an endless loop flattened into two layers (40, 42) along fold lines (38). CD yarns (28) are removed from the folds (38) to create extended ravel areas. This leaves the MD yarns (26) unbound in the ravel areas. Seam loops (56) are then formed from the unbound MD yarns (26) at the folds (38). CD materials (82, 84) (e.g. continuous CD yarns) are affixed to (rewoven into) the fabric along the edges of the ravel area at each fold (38). The affixed CD materials bind the CD yarn tails along the edges of the ravel areas to prevent migration of CD yarn tails into the seam area.
