<p>A nonwoven papermaker's fabric, usable in the dryer section of a paper machine, has a spiral wound machine direction (MD) base layer of raw stock which is wound around a pair of parallel rolls or cylinders until the desired length and width is achieved. The spiral wound MD layer is overlaid with a cross-machine direction (CD) layer of similar or dissimilar raw stock and mated by any of a number of means. The spiral wound MD layer can also be mated to another MD layer spiraled in the opposite direction and in one embodiment further mated to a CD layer. The fabric is preferably produced so that its neutral line is oriented toward the paper side of the fabric so that the paper sheet will stretch less than when typical dryer fabrics are used to turn the paper sheet and fabric around the dryer cylinders.</p> |
