      These men are located near the rolls in a pulpit, which is usually completely inclosed with heavy close-meshed netting or boiler plate, so that if a cobble occurs they will be protected from the rods which fly in all directions on such occasions.
    • 1915, Proceedings of Association of Iron & Steel Electrical:
      The ideal control which they offer the reversing motor is such, when a cobble might be made in the steel mill, the metal can be handled gently, and very often the ingot saved.
    • 1919 April, “Rolling Mill Research Laboratory Founded”, in Blast Furnace and Steel Plant, volume 7:
      In practical mill work a roller often has to wait days and sometimes weeks before he can catch this condition, as he could not consider the stopping of production while he made a cobble in some particular roll pass that was giving him trouble, and it is mainly by studying the cobbles that the action of the steel can be observed and studied.
    • 2009, Vladimir B. Ginzburg, Flat-Rolled Steel Processes: Advanced Technologies, page 231:
      Cameras pointed between stands could be saved for 5 or 7 days, enough to troubleshoot cobble or off-level mills.
