Hopper and Bowl feeds receptacles through a dual inline track to a dead track where they are oriented then picked and placed 2 up into a double nest on a 12 position indexed dial plate. Bowl fed primers are loaded and pressed into the receptacle using 2 primer load stations (each loading 2-up) and then height checked using 2 height check stations. Reject assemblies are offloaded into a trash box. Good assemblies are offloaded into 1 of 2 good part boxes. When the selected good part box is full, the other good part box is automatically placed under the chute and the full box is then manually replaced by an empty box.
