<p>A method and apparatus for wrapping coils (1) of metallic strip and the like to protect against atmospheric corrosion are described. A plastic film sleeve (4) is inserted through the open cylindrical centre (2) and held in place by flanged collars (3) at each end. The sleeve (4) is turned back over the collars (3) and the ends are loosely stuffed into the open cylindrical centre (2). The entire coil is then cocoon wrapped using relatively wide stretch-wrap film (10). The cocoon wrapping (10) is then sealed to the turned-over sleeve (4) in the vicinity of the end collars so as to seal the coil (1) within a continuous plastic film. The excess cocoon wrapping and sleeve material overlying the cylindrical centre can be trimmed away to leave an open centre to receive coil handling equipment.</p> |
