摘要： The present invention is directed relates to a method of applying a thin thermoset or thermoplastic cover over a golf ball subassembly by simultaneously dispensing polyurethane into multiple molds while using multiple mixers from multiple polyurethane sources. The method employs a continuous conveyor system wherein pre-heated first (top) and second (bottom) mold halves are pre-heated and pre-sorted prior to a polyurethane material being deposited in each mold half, preferably, each mold half comprises four cavities. A rotary table maneuvers the mold halves into position to receive a shot of polyurethane in each cavity. The polyurethane is dispensed from two separate mixers, each mixer having a pair of dispensing nozzles capable of shuttling back and forth between the cavities. To maintain process integrity, it is imperative that polyurethane dispensed into a particular top mold half and the polyurethane dispensed into the corresponding mated bottom mold half be from the same polyurethane mixer. The method of the invention provides a mechanism to maintain that the shot of polyurethane in each mold half is dispensed from the same mixer.
