Abstract
A transfer belt for carrying a fibrous web and a papermaking or similar machine. The transfer belt consists of a supporting substrate of a polymer foam and a reinforcement layer of aramid or glass fiber in either fabric or layer foam and a release layer that overlies and is bonded to the supporting substrate. The release layer is formed from a material promoting release of the fibrous web. The release layer may be selected from a variety of materials. The layers each contribute their own function to the operation of the belt to provide superior performance.
