ABSTRACT:
A method and apparatus for wrapping coils of metallic strip and the like to protect against atmospheric corrosion are described. A plastic film sleeve is inserted through the open cylindrical centre and held in place by flanged collars at each end. The sleeve is turned back over the collars and the ends are loosely stuffed into the open cylindrical centre. The entire coil is then cocoon wrapped using relatively wide stretch-wrap film. The cocoon wrapping is then sealed to the turned-over sleeve in the vicinity of the end collars so as to seal the coil 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.
