Abstract
A method of making a top toothed endless power transmission belt construction that is formed mainly of polymeric material and a belt construction made by such method are provided, the method comprising the steps of disposing the material in substantially cylindrical form on a substantially cylindrical drum-like support member, disposing a substantially cylindrical toothed member about the disposed material, compressing one of the members toward the other of the members with the pressure of pressurized steam to form top teeth in the material and cure the thus formed material with the heat of the steam into a top toothed belt construction, introducing pressurized steam against the other member during part of the time that the one member is being compressed toward the other member by the pressure of the pressurized steam, and temporarily releasing the pressure on the one member before the polymeric material has been cured to permit the gas that has been initially heated and thereby expanded in the polymeric material to escape therefrom, and temporarily releasing the pressure against the other member at the same time that the pressure on the one member is released, the step of temporarily releasing the pressure against the other member ending after the step of temporarily releasing the pressure on the one member ends so that when the pressure on the one member is initially reapplied a maximum pressure differential exists across the one member and acts in a direction to compress one member toward the other member for a period of time before the pressure on the other member is initially reapplied.
