ABSTRACT:
A papermakers fabric for use in papermaking and which is made from a plurality of elongated, linked, slotted elements. The elongated elements can be formed by extrusion or by lamination and are linked one to the next either by an integral tongue or through the use of a pintle connecting means which extends from one elongated element to the adjacent element. The desired permeability can be provided by forming apertures in the elongated elements and can be such that the permeability of the fabric varies in the cross machine direction. The permeability of the papermakers fabric can also be adjusted by varying the tension in the fabric in the machine direction. Individual elongated elements can also be configured so that the high-wear areas of the fabrics, for example the edges, have a greater material thickness than the low-wear areas and so that the cross section of the fabric can be varied to compensate for roll crown or other roll irregularities.
