WRAPPER FOR METAL COILS
A wrapper for wrapping a cylindrical roll of coiled material, such as coiled steel, is a one-piece wrapper which covers the outer periphery, the ends and the inner periphery of the roll. The wrapper has a first portion for covering the ends and outer periphery and a second portion for covering the inner periphery. Draw strings are provided at the longitudinal edges of the first portion for cinching the wrapper against the ends of the roll.
1 . A wrapper for wrapping a cylindrical roll of coiled material, the roll comprising an outer periphery, first and second ends and a hollow bore extending between the first and second ends and defining an inner periphery of the roll, the wrapper comprising:
(a) a first portion for covering the outer periphery and the first and second ends of the roll, the first portion having opposed first and second longitudinal edges;
(b) a second portion for covering the inner periphery of the roll, the second portion having opposed first and second longitudinal edges, the first longitudinal edge of the second portion being adjacent to the second longitudinal edge of the first portion;
(c) a first drawstring extending along a length of the wrapper proximate the first longitudinal edge of the first portion;
(d) a second drawstring extending along the length of the wrapper proximate the second longitudinal edge of the first portion and the first longitudinal edge of the second portion.
2 . A wrapper according to claim 1 , wherein the first portion and the second portion are separate sheets affixed together.
3 . A wrapper according to claim 1 , wherein the first portion and the second portion comprise a single, integral sheet.
4 . A wrapper according to claim 1 , wherein the first portion is thicker than the second portion.
5 . A wrapper for wrapping a cylindrical roll of coiled material, the roll comprising an outer periphery, first and second ends and a hollow bore extending between the first and second ends and defining an inner periphery of the roll, the wrapper comprising:
a sheet having a length and a width and first and second longitudinal edges;
a first drawstring extending along the length of the sheet proximate the first longitudinal edge;
a second drawstring extending along the length of the sheet between the first and second longitudinal edges, generally parallel to the first drawstring and at a first distance therefrom;
the portion of the wrapper between the first and second drawstrings comprising a first portion of the wrapper and the portion of the wrapper between the second drawstring and the second longitudinal edge comprising a second portion of the wrapper, the first portion being sized for covering the outer periphery and the first and second ends of the roll, and the second portion being sized for covering the inner periphery of the roll.
6 . A wrapper according to claim 1 , further comprising a first drawstring pocket and a second drawstring pocket extending along the length of the wrapper for holding the first and second drawstrings respectively.
7 . A wrapped cylindrical roll of coiled material, comprising:
(a) a cylindrical roll of coiled material, the roll comprising an outer periphery, first and second ends and a hollow bore extending between the first and second ends and defining an inner periphery of the roll;
(b) a wrapper comprising:
(i) a first portion for covering the outer periphery and the first and second ends, the first portion having opposed first and second longitudinal edges;
(ii) a second portion for covering the inner periphery, the second portion having opposed first and second longitudinal edges, the first longitudinal edge of the second portion being adjacent to the second longitudinal edge of the first portion;
(iii) a first drawstring extending along a length of the wrapper proximate the first longitudinal edge of the first portion;
(iv) a second drawstring extending along the length of the wrapper proximate the second longitudinal edge of the first portion and the first longitudinal edge of the second portion;
(c) the first portion covering the outer periphery and the first and second ends of the roll, the second portion covering the inner periphery of the roll and the first and second drawstrings being cinched to hold the wrapper against the respective first and second ends of the roll, proximate the inner periphery thereof.
8 . A wrapped cylindrical roll of coiled material, comprising:
(a) a cylindrical roll of coiled material, the roll comprising an outer periphery, first and second ends and a hollow bore extending between the first and second ends and defining an inner periphery of the roll;
(b) a wrapper comprising:
a sheet having a length and a width and first and second longitudinal edges;
a first drawstring extending along the length of the sheet proximate the first longitudinal edge;
a second drawstring extending along the length of the sheet between the first and second longitudinal edges, generally parallel to the first drawstring and at a first distance therefrom;
the portion of the sheet between the first and second drawstrings comprising a first portion of the wrapper and the portion of the sheet between the second drawstring and the second longitudinal edge comprising a second portion of the wrapper;
(c) the first portion of the wrapper covering the outer periphery and the first and second ends of the roll, the second portion of the wrapper covering the inner periphery of the roll, and the first and second drawstrings being cinched to hold the wrapper against the respective first and second ends of the roll, proximate the inner periphery thereof.
9 . A wrapped roll according to claim 7 , wherein the second portion of the wrapper comprises a part thereof tucked under the first portion of the wrapper at the first end of the roll.
10 . A method of wrapping a cylindrical roll of coiled material, comprising the steps of:
(a) providing the cylindrical roll of coiled material, the roll comprising an outer periphery, first and second ends and a hollow bore extending between the first and second ends and defining an inner periphery of the roll;
(b) providing a wrapper comprising:
(i) a first portion for covering the outer periphery and the first and second ends of the roll, the first portion having opposed first and second longitudinal edges;
(ii) a second portion for covering the inner periphery of the roll, the second portion having opposed first and second longitudinal edges, the first longitudinal edge of the second portion being adjacent to the second longitudinal edge of the first portion;
(iii) a first drawstring extending along a length of the wrapper proximate the first longitudinal edge of the first portion;
(iv) a second drawstring extending along the length of the wrapper proximate the second longitudinal edge of the first portion and the first longitudinal edge of the second portion;
(c) wrapping the first portion of the wrapper around the outer periphery of the roll, inserting the second portion of the wrapper through the hollow bore of the roll, cinching the second drawstring at the second end of the roll, proximate the inner periphery, applying a part of the second portion of the wrapper to the first end of the roll, and cinching the first drawstring at the first end of the roll, proximate the inner periphery, such that the first portion overlaps the part of the second portion.
