  • Patent number: 5546657
    Abstract: A method of automatically assembling wiring devices of the type having mounting straps in a continuous sequence, the disclosed wiring device being a duplex wall receptacle. A strip of the mounting strap material is fed longitudinally, being alternately moved by equal increments and stopped to place each segment of the strip progressively at a plurality of operational stations. Portions of the strip are removed to form blanks for the mounting straps which remain mutually attached at positions along each side of the strip which form end portions of the blanks and, ultimately, of the mounting straps. One or more additional strips in which ground contact blanks have been formed are fed in a direction perpendicular to that of the first strip and the ground contact blanks are staked to the mounting strap blanks and severed from their respective strips.
