  • Patent number: 4487539
    Abstract: In the production of metal cans, a sheet metal body plate (blank) is scored with aligned upper and lower score lines and then formed into a cylindrical single can body. Preferably the scoring is in steps; first, scoring the upper score line using a scoring roller and an anvil wheel; and, secondly, scoring the lower score line using a second scoring roller and a second anvil wheel. Then the single can bodies are conveyed by a conveyor belt and rolled over the knife edge (parting edge) of an elongated parting rail, with the parting edge aligned with the score line and with the conveyor applying pressure on each can body to part each one on the parting edge, thereby forming two can bodies from the single can body.
