A process for making a mat having a fabric layer and a rubber backing layer using a press having an inflatable bag, a heated platen, and a frame defining the extent of the periphery of the mat located between the bag and the platen, the process comprising the steps of:placing a fabric layer and an uncured rubber backing layer in the press between the inflatable bag and the heated platen; and,inflating the bag to press the fabric and uncured rubber backing layers against the heated platen by applying a pressure over substantially the whole area of the backing layer, to heat-cure the rubber layer and adhere it to the fabric layer, wherein the height of the frame is greater than the thickness of the uncured rubber backing layer, so that the rubber backing layer, when cured and adhered to the fabric layer in a finished mat, has an integral thickened peripheral portion.
