Patent

CA 2206087

A method for manufacturing a papermaker's fabric by spirally winding a woven fabric strip, narrower than the intended width of the fabric, and the papermaker's fabric manufactured in accordance with the method, are disclosed. The fabric strip includes lengthwise and crosswise yarns, and has a lateral fringe along at least one lateral edge thereof, the lateral fringe being unbound ends of the crosswise yarns extending beyond the lateral edge. During the spiral winding of the fringed strip, the lateral fringe of a turn overlies or underlies an adjacent turn of the strip. The lateral edges of adjacent turns abut against one another. The spirally continuous seam so obtained is closed by ultrasonically welding or bonding the overlying or underlying lateral fringe to the fabric strip in an adjacent turn.
