Claims
- 1. In combination, an individual ribbon coil of metal sheeting, a protective wrapper of metal sheeting to protect the coil from damage and from atmospheric corrosive agents comprising, two separate discoidal end caps for completely enclosing the coil circumferentially and axially and each having a cylindrical band defining a sleeve and an annular, radially inwardly projecting end flange and an opposite end of the band being open, the discoidal end caps being disposed on the coil on opposite ends thereof with the corresponding bands circumferentially of the coil extending toward each other, each band having a width greater than half the axial length of the coil so that the marginal edges at the open end of the bands overlap circumferentially and axially disposed on the coil, the end flange of each cap having a radial extent inwardly toward the center of the coil at least equal to the radial thickness of the coil, each end flange having flexible corrugations disposed radially from the center of the coil, the depth of which increases progressively toward the center of the coil, and the protective wrapper discoidal end caps being made of metal sheeting from rejected ribbon coil metal sheeting similar in dimension to the metal sheeting of the individual coil being protected, whereby the coil is housed internally of the two sleeves each with one end open and an opposite end partially closed by a corresponding flange capping the opposite ends of the coil to effectively protect the turns of the coil.
- 2. In combination, an individual cylindrical ribbon coil of coiled metal sheeting, a protective wrapper of metal sheeting to protect the coil from damage and from atmospheric corrosive agents according to claim 1, in which each said band is split and one half the band has a circumferential extent over 180.degree. of the coil, the flange of each split band having a circumferential extent corresponding to that of the band so that the two halves of each band and the flange thereon overlap circumferentially of the coil.
- 3. In combination, an individual cylindrical ribbon coil of coiled metal sheeting, a protective wrapper of metal sheeting to protect the coil from damage and from atmospheric corrosive agents according to claim 1, in which each discoidal end cap is split into two halves.
- 4. In combination, an individual cylindrical ribbon coil of coiled metal sheeting, a protective wrapper of metal sheeting to protect the coil from damage and from atmospheric corrosive agents according to claim 1, including a treated paper wrapping on the coil disposed underlying the protective discoidal end caps.
- 5. In combination, an individual cylindrical ribbon coil of coiled metal sheeting, a protective wrapper of metal to protect the coil from damage and from atmospheric corrosive agents according to claim 4, in which said paper comprises a lining bonded on the inner surfaces of the discoidal end caps.
- 6. In combination, an individual cylindrical coil of coiled metal sheeting, a protective wrapper of metal sheeting to protect the coil from damage and from atmospheric corrosive agents according to claim 1, including two inserts for positioning each in the center opening of the coil, each insert comprising a tubular sleeve open at both ends and having a radial flange extending outwardly of the tubular sleeve, each sleeve having an axial extent less than half the width of the coil, and the two inserts being disposed in the coil with the corresponding sleeve thereof extending inwardly into the center of the coil and the radial outward flange thereof overlapping a corresponding end cap on the coil, whereby the coil is completely enclosed in the protective wrapper.
- 7. In combination, an individual cylindrical ribbon coil of coiled sheet metal, a protective wrapper of metal sheeting to protect the coil from damage and from atmospheric corrosive agents according to claim 1, in which each discoidal end cap is split into two halves, the band of each half having a circumferential extent greater than 180.degree. of the circumference of the coil to be protected, and the annular flange of each discoidal end cap band having the same circumferential extent as the corresponding band thereof.
