  • Gasket forming apparatus
    Patent number: 4118850
    Abstract: A metal forming apparatus and method which uses the apparatus for closing the metal shell at a corner of a double jacketed gasket assembly. The apparatus includes a roller hammer means having a metal forming tool rotatably mounted eccentrically in a power-driven rotating tool holder mount for free rotation of the tool relative to the rotating tool holder upon engagement of the tool with a gasket shell. The eccentric mounting provides a reciprocating hammering motion to the tool and the free rotation allows the tool to roll along the gasket shell during engagement to avoid tearing of the gasket shell.
