Abstract
Abstract A method of packaging a coil of strip material is described. The strip material may be steel strip and the method includes wrapping protective steel strip material around the outer circumference of the coil to provide axially overhanging circumferential edges at each end of the coil which are deformed radially inwardly to retain a steel annulus coated with flexible foam abutted against the ends of the coil laps.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
97 words
A method of packaging a coil of metal strip material including wrapping steel sheet protective material around the circumference of the coil with an axially outwardly directed overhanging projection of said protective material around the outer circumferential edge at each end of the coil; inserting protective material within the eye of the coil; applying a steel sheet annular member to each end of the coil within said overhanging projection of protective material; and providing annular flexible cushioning at at least the radially outermost edge of said annular member immediately adjacent to said overhanging projection of protective material.
Claim 2
Independent Claim
97 words
A method of packaging a coil of metal strip material including wrapping steel sheet protective material around the circumference of the coil with an axially outwardly directed overhanging projection of said protective material around the outer circumferential edge at each end of the coil; inserting protective material within the eye of the coil; applying a steel sheet annular member to each end of the coil within said overhanging projection of protective material; and providing annular flexible cushioning at at least the radially outermost edge of said annular member immediately adjacent to said overhanging projection of protective material.
Claim 3
Independent Claim
97 words
A method of packaging a coil of metal strip material including wrapping steel sheet protective material around the circumference of the coil with an axially outwardly directed overhanging projection of said protective material around the outer circumferential edge at each end of the coil; inserting protective material within the eye of the coil; applying a steel sheet annular member to each end of the coil within said overhanging projection of protective material; and providing annular flexible cushioning at at least the radially outermost edge of said annular member immediately adjacent to said overhanging projection of protective material.
Claim 4
Independent Claim
97 words
A method of packaging a coil of metal strip material including wrapping steel sheet protective material around the circumference of the coil with an axially outwardly directed overhanging projection of said protective material around the outer circumferential edge at each end of the coil; inserting protective material within the eye of the coil; applying a steel sheet annular member to each end of the coil within said overhanging projection of protective material; and providing annular flexible cushioning at at least the radially outermost edge of said annular member immediately adjacent to said overhanging projection of protective material.
Claim 5
Dependent Claim
34 words
A method according to claim 1 wherein each said annular member is coated with a cushioning material providing said flexible cushioning prior to positioning a said annular member at each end of the coil.
Claim 6
Dependent Claim
35 words
A method according to claim 1 wherein said cushioning is applied to the axially outer surface of each said annular member around its outer circumferential edge after being positioned adjacent the end of the coil.
Claim 7
Dependent Claim
44 words
A method according to claim 1 including the further step of deforming said overhanging projection of protective material in a radially inwardly direction at each end of the coil to overlie each said annular member and associated flexible cushioning at their radially outer edges.
Claim 8
Dependent Claim
58 words
A method according to claim 1 including the further step of forming a plurality of spaced perforations in the said protective material before it is wrapped around the circumference of the coil whereby, when said material is wrapped around the coil, said perforations are disposed adjacent each end of the coil in spaced circumferential relation with one another.
Claim 9
Dependent Claim
35 words
A method according to claim 5 wherein said perforations are formed in the apices of respective upstanding frusto-conical projections which, when the protective material is wrapped around the coil, extend radially outwardly of the coil.
Claim 10
Dependent Claim
14 words
A method according to claim 1 wherein said flexible cushioning comprises a foam material.
Claim 11
Dependent Claim
38 words
Packaged strip material as claimed in claim 8 wherein said cushioning and said annular member are substantially co-extensive with one another at each end of the coil and extend from the eye thereof to the outer circumferential edge.
Claim 12
Dependent Claim
42 words
Packaged strip material as claimed in claim 8 wherein said overhanging projection of protective material is deformed radially inwardly at each end of the coil to overlie each respective said stiff annular member and its associated cushioning at their radially outer edges.
Claim 13
Dependent Claim
28 words
Packaged strip material as claimed in claim 8 wherein said protective material is provided with a plurality of circumferentially spaced perforations therein adjacent each end of the coil.
Claim 14
Dependent Claim
41 words
Packaged strip material as claimed in claim 8 wherein a plurality of circumferentially spaced upstanding frusto-conical projections extenD radially outwardly of said protective material adjacent each end of the coil, said perforations being formed at the apices of respective said projections.
Claim 15
Dependent Claim
16 words
Packaged strip material as claimed in claim 8 wherein said flexible cushioning comprises a foam material.
