Abstract
An apparatus and method for manufacturing a synchronous drive belt or timing belt is disclosed. The method allows a belt with axially interlocked teeth to be manufactured. The method utilizes transfer molding, as opposed to compression molding, and involves an inflatable diaphragm which pushes rubber radially outwardly from a mandrel into a mold having teeth on an inner surface. The method includes the provision of a barrier layer which can be advantageously built into the belt to improve the transfer molding process.
