Abstract
Apparatus and methods for handling a superlarge coil of metal strip formed from an entire heat of metal and having a coil weight up to about 8000 lbs./in. of coil width, by coiling the strip on a coiling mandrel until the weight approaches that which the mandrel cannot support, then supporting the coil on a plurality of driven rollers disposed in a curved pattern conforming to the shape of the coil and mounted on a vertically and horizontally movable carriage, completing the coiling, and moving the carriage and thereon-supported coil to an uncoiling station and there rotating the driven rollers to unwind the coil preparatory to a further continuous treatment of the strip.
