<p>A mat particularly a washable dust control mat, having a fabric layer (2) and a rubber backing layer (4) with a border extending beyond the fabric layer is made using a press which heat-cures the rubber and adheres it to the fabric and employs an inflatable bag to apply pressure by pressing the layers against a heated platen, wherein a frame (14) defining the extent of the border is located between the bag and the platen, and wherein the bag applies pressure to the assembled layers including the border portion of the backing layer. The frame can act as a dam for preventing outward movement of the rubber and provide an integral thickened border; in some cases it also provides a guillotine for trimming the rubber during pressing.</p> |
