  • Patent number: 4532093
    Abstract: A method and system are described for manufacturing molded packings used in the shipment of articles such as computers, typewriters and the like. The system employs a plurality of mold plugs positioned on a rotating platform whereby the mold plugs are alternately moved between work stations. At one work station a separator sheet is manually placed over a mold plug. At another work station a foaming material dispensing gun is automatically operated in a predetermined pattern over a mold which encloses the mold plug. The pattern is manually adjustable to fit any particular mold plug. Control over the system is obtained with a microprocessor programmed to operate with sensors and actuators associated with the system.
