Abstract: A conveying system useful for synchronous conveying of articles along a straight line path between a driving and driven pulley. Selected teeth of a synchronous belt are modified to provide passages between a backing and a top land. Each modified tooth is formed with a reduced addendum. A tip plate is bolted to the top land of the modified teeth so that the height of the teeth become compatible with the standard size teeth of the belt. The tip plate bolts are also used to fasten transporting devices to the backing of the belt at the locations of the nonstandard teeth.

Abstract: Synchronous conveying belts are formed by modifying teeth grooves of a molding gear used in a molding device employing the gear. A groove plate is configured to fixedly mount in a bottom land of selected teeth of the molding gear for reducing the depth of the selected teeth of the belt to be molded. Sleeves for fixedly attaching the groove plate to the bottom land serve as molding post for forming passageways in the modified teeth extending from a backing of the belt to a top land of the modified teeth. Upon forming the reinforced elastomeric belt using the modified molding gear, transporting devices can be fastened to the backing of the belt using attachment fixtures.
