ABSTRACT:
There is disclosed in the present application an apparatus for sorting acceptable molded parts from material coming from a molding machine and requiring to be reprocessed or recycled. The present apparatus includes an auger formed with closely spaced flights in a receiving zone and more widely spaced flights in a transport zone in which scrap such as sprues, runners and defective molded parts are carried to a scrap discharge area. The acceptable articles, which have already been separated from the sprues and runners upon discharge from the mold, are of a size which allows them to pass between the closer flights of the receiving zone whereas the sprue and runner assemblies are carried by both the closer and more widely spaced flights to the scrap discharge area.
