What does a Roller do?
Operates rolling machine to roll ingots into metal strips for use in stamping out jewelry blanks: Positions ingot between pressure rollers. Turns handwheel and observes calibrated scale indicator to set distance between rollers. Moves lever to start machine, and readjusts pressure rollers as needed to reduce ingots to strips of specified thickness. Verifies thickness of strips, using micrometer. May anneal ingot to soften for further rolling.
