A method of making a power transmission belt/belt sleeve, which method includes the step of providing a first mold assembly having a central axis and a circumference, providing a sheet material having first and second oppositely facing surfaces, placing the sheet material around the first mold assembly and causing a contoured portion of the first surface to be keyed to the first mold assembly so that the sheet material is in a predetermined circumferential position relative to the first mold assembly, providing a second mold assembly having a contoured surface, placing the contoured surface of the second mold assembly against the second surface of the sheet material, providing a guide element, operatively connecting the guide element between the first and second mold assemblies so that the guide element maintains the second mold assembly in a predetermined circumferential position relative to the first mold assembly, and forming the second surface of the sheet material through the contoured surface of the second mold assembly with the first and second mold assemblies and sheet material in an operative relationship. The contoured portion of the first surface of the sheet material can be pre-formed or formed in place on the first mold assembly. |
