ABSTRACT:
A method and apparatus for slitting and separating a wide roll of gasket material of varying thicknesses into narrower rolls of uniform thicknesses. A wide roll of gasket material is slit into a plurality of narrow rolls. Each roll is passed under a roller at a pressure simulating the working load pressure of the gasket. A thickness gauge and probe is employed to determine thickness of the material as it passes between the rollers. The web of material is cut when the thickness exceeds specified tolerances and the separated lengths are collated in separate rolls of uniform thickness. Gaskets are stamped or cut from the collated rolls and for quality control a gasket from a group of gaskets is measured for thickness under the simulated working load pressure. The thickness gauges employed in the rollers and quality control are calibrated against one another to ensure uniformity of measurement.
