Other methods of compensating for roll deformation include continual varying crown (CVC), pair cross rolling, and work roll bending ...

Famous quotes containing the word roll:

    Rock ‘n’ roll is a combination of good ideas dried up by fads, terrible junk, hideous failings in taste and judgment, gullibility and manipulation, moments of unbelievable clarity and invention, pleasure, fun, vulgarity, excess, novelty and utter enervation.
    Greil Marcus (b. 1945)
