  • Cl B65d 85/02, B65d 85/54 method includes wrapping protective steel strip mate- Field Of Search 206/3 39 rial around the outer circumference of the coil to pro- 206/400, 401, 402, 405, 406, 407,.413-416; vide axially overhanging circumferential edges at each 53/13, 204, 32 end of the coil which are deformed radially inwardly to retain a steel annulus coated with flexible foam [56] References Cited abutted against the ends of the coil laps.
  • COIL PACKAGE AND METHOD OF FORMING A PACKAGE Coils of strip material such as steel strip have to be packaged to protect them during transit. It is usual to package coils of steel strip by hand, usually by wrapping turns of substandard strip around the coil, holding them in position with straps and bending portions of the wrapping strip around the ends of the coil. This is very time consuming and does not provide a very protective package. Proposals have also been made, for example in US. Pat. No. 3,198,418 to provide a preformed container into which a coil of steel is placed.
  • a method of packaging a coil of strip material includes wrapping protective material around the circumference of the coil with an axially outwardly directed overhanging projection of protective material around the outer circumferential edge at each end ofthe coil, providing protection for the eye ofthe coil, providing a stiff annular member of protective material adjacent each end of the coil within the overhanging projection of protective material and providing annular flexible cushioning at least the radially outermost edge of said annular member immediately adjacent to said overhanging projection of protective material.
  • a packaged coil of strip material is provided with protective material wrapped around the circumference of the coil with an axially outwardly directed overhanging projection of protective materialaround the outer circumferential edge at each end of the coil, protective material provided in the eye of the coil, a stiff annular member of protective material adjacent each end of the coil within the overhanging projection of protective material and an annular flexible cushioning at at least the radially outermost edge of said annular member immediately adjacent to said overhanging projection of protective material.
  • the annular member which is conveniently steel sheet, is first coated on one side with a protective coating constituting the aforesaid cushioning, the protective coating being typically a flexible non-porous material such as a polyurethane foam.
  • the annular member may not first be coated, but may have an annular protective layerconstituting the cushioning applied around its outer circumferential edge after being positioned adjacent the end of the coil.
  • This layer is suitably a flexible one part material such as polyurethane froth applied from an aerosol can or other suitable means.
  • the annular member is generally planar and the outer diameter thereof is suitably just less than the diameter of the wrapping of protective material.
  • the inner diameter of the annular member is preferably approximately the same as the diameter of the eye of the coil of strip material.
  • the overhanging projection is preferably bent over so that it extends radially inwardly over part of the annular member and at least part of the cushioning.
  • the protection for the eye of the coil suitably includes a tube of protective material such as steel sheet.
  • the protection for the eye of the coil may include an eye trumpet extending partially into the eye and partially across the end of the coil at each end of the eye of the coil.
  • a sealing compound may be applied around the outer and inner circumferential edges at each end of the coil so as to provide a waterproof seal between the junctions of the protective material.
  • the outer turn of the coil may be unwound to be subsequently wound backon the coil as protective material, and protective material may be interposed between the outer turn and the rest of the coil to form the overhanging projections around the outer circumferential edges.
  • a sheet of further protective material such as waterproof paper may be interposed between the outer turn and the rest of the coil.
  • the outer turn may be unwound from the coil by rotating the coil in one sense, and may then be wound back onto the coil with protective material interposed between the outer turn and the rest of the coil by rotating the coil in the opposite sense.
  • a plurality of spaced perforations may be formed in the protective'material before it is wrapped around the circumference of the coil, such perforations being formed in the apices of respective upstanding frustoconical projections which, when the protective material is wrapped around the coil, extend radially outwardly of the protective material in spaced circumferential relation with one another,
  • Such perforations permit drainage of water which may accumulate inside the packaged coil whilst at the same time, by nature of their frusto-conical configurations, substantially prevent the direct entry of rain water therethrough if the package is exposed to the elements.
  • FIG. 1 shows schematically a longitudinal section of one coil packaged according to the invention
  • FIG. 2 is an enlarged detail of FIG. 1,
  • FIG. 3 is an enlarged detail of FIG. 1 showing a modification of the package
  • FIG. 4 shows schematically a longitudinal section of another coil packaged according to the invention
  • FIG. 5 shows a detail of a further modification to the packaged coil of FIG. 1,
  • FIG. 6 shows a suitable coil packaging apparatus for carrying the invention into effect
  • FIG. 7 is an enlarged detail of the FIG. 1 package showing a modification to the wrapping protective material and
  • FIG. 8 is a transverse cross sectional view of apparatus for forming modified wrapping material.
  • FIGS. 1 and 4 show each element of the package as discrete and separate. Like references are used to denote like parts in all the Figures.
  • a coil 10 of steel strip having an eye 11 has protective steel sheet material 12 wrapped around its circumference, with an overhanging projection 13 of steel sheet around the outer circumferential edge at each end of the coil 10.
  • a tube of protective steel sheet material 14 is also provided in the eye 11 of the coil 10.
  • An annular generally planar steel sheet 15 coated'with a protective coating 16 of polyurethane foam constituting cushioning lies adjacent each end of the coil 10 so that the protective coating 16 is pressed against the coil 10.
  • the outer diameter of the annularshaped steel sheet 15 is slightly'less than the diameter of the wrapping of sheet material 12.
  • Sheets of waterproof paper 17, which is a further protective material, are interposed between the coil 10 and the wrapping of sheet material 12.
  • the water proof paper 17 also extends radially inwardly between the ends of coil 10 and the protective coating 16 and is also tucked axially inwardly into the eye 11 to overlie a tu' bular inner paper wrapping within the eye as is clearly illustrated in FIGS. 1 and 2.
  • the inner circumferential edges of the coil are also protected by sheet steel eye trumpets 18 which extend partially into the eye 11 and partially across the end of the coil 10.
  • a series of steel bands 19 secure the various elements of the package to the coil 10. Each band 19 runs through the eye 11 of the coil 10 and around an annular section of the coil 10.
  • FIG. 3 A modification of the package hereinbefore described with reference to FIGS. 1 and 2 is shown in FIG. 3.
  • a sealing compound of a bitumastic material is applied around the outer and inner circumferential edges of the coil 10 at each end of the coil 10 so as to provide a waterproof seal between the junction of the protective steel sheet material 12 and the coated annular steel sheet 15.
  • the coil 10 in FIG. 3 is shown as having a curved edge 21. This is a fairly common occurrence in the winding of coils of steel strip and can give rise to packaging problems. However, with the present invention, the protective coating of polyurethane foam 16 deforms as shown to accommodate variations in the winding of the coil 10.
  • FIG. 4 a variation in the package is shown which does away with the eye trumpet 18 shown in FIGS. 1 to 3 although attendant upon the winding of the coil the axially outwardly directed overhanging projection 13- of steel sheet around the outer circumferential edge of coil 10 is deformed radially inwardly to partly overlap the sheet 15 and the radially outermost part of the cushioning 16 so that sheet 15 and cushioning l6 lie within the overhanging projection 13 at each respective end of the coil 10.
  • An annular steel sheet member 22 coated with polyurethane foam 16 covers each end of the coil 10 and extends into the eye 11 of the coil 10.
  • a sealing compound can be applied to the outer circumferential edge of the coil if required.
  • Both the annular sheet member 22 of FIG. 4 and the annular sheet 15 of FIGS. 1 to 3 are coated with polyurethane foam l6 and the foam 16 is allowed to dry prior to the application of the sheet member 15 or 22 as the case may be to the coil 10. This means that there is no need for the use of arelease agent on the ends of the coil 10 to prevent sticking of the foam 16 to the ends of coil 10.
  • FIG. 5 A further variation of the package is seen in'FIG. 5 wherein the annular steel sheet member 15 lies directly adjacent the end of coil 10.
  • the overhanging projection 13 of steel sheet around the outer circumferential edge of coil 10 is deformed radially inwardly and folded over an annular cushioning ring of dried one part polyurethane froth 23 when the coil 10 is handed by bands 19.
  • the one part polyurethane froth 23 is applied from an aerosol'can to the periphery of the annular member 15 and dries rapidly to form a protective layer around the outer circumferential edge of coil 10. Since this edge is the part of coil 10 most likely to be damaged by handling this variation provides a suitable alternative means of protecting the edges of coil 10 to the means previously described.
  • the outer protective steel sheet material 12 and wrapping papers 17 are applied as hereinbefore described with reference to FIGS. 1 to 3.
  • the packaging apparatus schematically illustrated in FIG. 6 includes a paper wrapping station 31, a steel sheet wrapping station 32 and third station 33 for final packaging and banding. 1
  • Coils 10 of steel strip arrive at the paper wrapping station 31 on a conveyor 34, and sheets of paper 17 from a paper dispenser 35 are then wrapped around coil 10. Coil 10 is rotated about its longitudinal axis to facilitate the paper wrapping operation.
  • The-coils 10, now wrapped in paper 17, are transferred to the steel sheet wrapping station 32.
  • Steel wrapping sheets 12 cut to an appropriate length to surround the coil 10 are dispensed from a steel sheet dispenser 36.
  • Coil 10 is then rotated to pull the steel sheets 12 tightly around its circumference care being taken to ensure that the coil has been centred relative to the sheets 12 so that there is an overhanging projection 13 of steel sheet 12 around the outer circumferential edge at each end of the coil.
  • the steel sheets 12 are then spot welded together to hold the wrapping in position.
  • annular steel sheets 15 are positioned adjacent each end of the coil within the overhanging projections 13 of steel sheets 12.
  • the protection for the ends of the coil 10 may include any of the variations previously described.
  • Steel eye bands 19 from a banding machine 37 are then applied to the packaged coil to cause the overhanging projections 13 of steel sheet 12 to bend over'radially inwardly and overlap part of the disc shaped sheet 15 and cushioning 16 and to secure the packaging.
  • a further apparatus for packaging the coils is similar to that shown in FIG. 1 of our US. Pat. No. 3670877.
  • the spraying tunnel shown in that figure is, however, not required and the insertion of the annular steel sheets 15 of the present invention takes place before the application of steel bands to the package.
  • the method of using the outer turn of the coil as protective material is as described in our US. Pat. No. 3670877.
  • each end of the wrapped material 12 is formed with a plurality of circumferentially spaced apart perforations 40 illustrated herein as being arranged at each end of the coil in two axially spaced rows.
  • the perforations 40 are formed at the apices of respective upstanding frusto-conical projections 42 extending radially outwardly of the wrapped coil.
  • the frusto-conical shape of the projections enables water to drain readily outwardly if entrapped at the ends of the coil package whilst at the same time rain water is substantially prevented from entering directly through the perforations 40 if the coil package is exposed to the elements.
  • the perforated frusto-conical projections 42 are formed in the wrapping protective material 12 conveniently at the steel sheet wrapping station 32.
  • the station 32 may include, in line with each end of the coil, a pair of co-operating rollers 44-46 through which the steel wrapping sheet 12 is fed prior to being wrapped around the coil 10.
  • the top roller 44 is provided with two axially spaced annular grooves 45 in its outer periphery of such a radial depth to receive two co-operating rings of frusto-conical radially outwardly extending studs 47 on a lower co-operating roller 46.
  • a method of packaging a coil of metal strip mate rial 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.
  • 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.
  • 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.
  • 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.
  • a packaged coil of metal strip material including: steel sheet protective material wrapped around the circumference of the coil with an axially outwardly di rected overhanging projection of protective material around the outer circumferential edge at each end of the coil; protective material in the eye of the coil; a steel sheet annular member adjacent each end of the coil within said overhanging projection of protective material; and annular flexible cushioning at at least the radially outermost edge of said annular member immediately adjacent saidoverhanging projection of protective material.
