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.
Claims14
A support, coiling, transportation and uncoiling rig for handling a coil of continuously rolled metal strip being partially coiled on a coiling mandrel of a coiling station following continuous processing, and being partially uncoiled on an uncoiling mandrel of an uncoiling station for further processing, comprising
- a vertically and horizontally movable carriage disposed during use beneath the coil and having a plurality of driven rollers disposed in a curved pattern forming a saddle for contacting, supporting and winding the coil by elevation of the saddle by elevation means and winding of the coil by the driven rollers for coiling of the strip when the weight of the coil during continuous processing approaches that which would be too great for support and coiling by the coiling mandrel, and uncoiling of the strip preparatory to further continuous processing until the weight of the coil is less than that which can be supported and uncoiled by the uncoiling mandrel.
A facility for the continuous rolling and coiling, into the form of a superlarge coil of rolled metal strip, an entire heat of metal and for subsequent continuous processing of the strip, comprising means to produce, continuously roll and coil the metal strip on a winding mandrel, a vertically and horizontally movable railed coil support, coiling, transportation and uncoiling rig disposed beneath the coil and having a plurality of spaced-apart driven rollers mounted on the rig in a curved pattern conforming to the shape of the coil, to contact, support and rotate the coil about its central axis upon elevation of the driven rollers for winding the strip when the weight of the coil during continuous processing approaches that which would be no longer supportable solely by the coiling mandrel, and to rotate the coil for unwinding the strip when the rig is transported horizontally to an uncoiling station preparatory to further continuous processing of the strip until the weight of the coil is less than that which is supportable by an uncoiling mandrel.
A method of handling a continuously rolled coil of metal strip, comprising initially coiling and supporting the strip on a coiling mandrel disposed in a coiling station, before the coil reaches a weight too great to be supported by the coiling mandrel, providing additional support to the coil by a plurality of driven rollers disposed beneath the coil in a curved pattern substantially conforming in shape to that of the coil and mounted on a vertically and horizontally movable carriage, disengaging the coil and the coiling mandrel, transporting the carriage and the completed, thus-supported coil to an uncoiling station, mounting the supported coil on an uncoiling mandrel, rotating the coil by means of the driven rollers to unwind the coil preparatory to further continuous treatment of the strip, lowering the carriage when the coil weight is reduced to a value supportable by the uncoiling mandrel, and returning the carriage to the coiling station.
A method of handling a coil of metal strip, comprising coiling a continuous length of strip on a coiling mandrel until the coil reaches a weight approaching that which cannot be supported by the coiling mandrel, then supporting the coil on a carriage disposed beneath the coil and having means for rotating said coil about its central axis, and completing the coiling of the strip by said rotating means into the form of a superlarge coil having a specific weight up to about 8000 lbs/in of coil width.
A method for handling a superlarge coil of continuous metal strip and having a coil specific weight up to about 8000 lbs./in. of coil width, comprising 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 substantially conforming to the shape of the coil and mounted on a vertically and horizontally movable carriage disposed beneath the coil, completing the coiling by means of the driven rollers, 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.
