Press pads

摘要

A press pad is provided for use in a laminate press. The pad comprises a woven fabric of heat resistant strands wherein at least a proportion of the weft comprises a core made up of a bundle of strands within a sheath of an elastomeric material and at least a proportion of the warp comprises metal strands. The strands forming the bundle are dose-packed prior to extrusion of the sheath around them. The transverse cross-sectional profile of the sheath is a regular geometric profile that is other than a circular profile prior to weaving of the fabric of the press pad. Preferably, the transverse cross-sectional profile of the sheath is a splined profile or a regular polygonal profile that is composed of straight lines or arcs.

1. A press pad for use in a laminate press, the press pad comprising:
a woven fabric of heat-resistant strands wherein at least a proportion of a weft of said woven fabric has a core formed of at least three strands within an extruded sheath of an elastomeric material and at least a proportion of a warp of said woven fabric is formed of metal strands, wherein said at least three strands are close-packed so that the strands occupy a minimal amount of space prior to the extrusion of the sheath around the strands, the sheath having a transverse cross-sectional profile of a non-circular regular geometric shape prior to weaving of the fabric.
