Definitions

  • This invention relates to an interior core protector and, more particularly, to the protection of the interior material in a roll of coiled'material, for example, a coil of sheet steel.
  • sheet steel e.g., that which is used extensively in the automobile industry
  • These coils weigh up to 15 tonnes and include a centre core or opening therethrough.
  • strapping of the coil to prevent its uncoiling, to place steel straps through the centre core and about the outside of the coil.
  • at least two and sometimes three or four of these straps spaced about the coil are used.
  • C-hook which comes down and passes through the centre core and is then raised to engage the interior surface of the material to lift the coil on and off the truck or railway car.
  • the C-hook often damages the metal particularly by bending of the edges of the material located at the centre of the coil. That is, when the C-hook is placed through the coil and raised upwardly into engagement with the material, it is rare that the hook ever engages the material at both edges with equal pressure. Rather, the hook typically first engages one edge and then the other. When this happens, the pressure of the hook on the material causes its bending. This bent material, of course, is not usable and must be scrapped. It is not uncommon for the user to have to scrap 10 to 15 metres or more of the: sheet'metal because of such damage.
  • the protector in accordance with the invention comprises a pair of overlapping angle members each of which has two legs one of which is provided with a plurality of cuts permitting bending of the member to conform to the circumference of the core, wherein the cuts in the leg of one of the members are offset with respect to the cuts in the leg of the other of the members so that in use each cut in either leg is covered by a portion of the other leg so as to provide protection around the entire circumference of the core.
  • the interior core protector includes a pair of overlapping formed angular paperboard members which are manufactured in a flat, i.e., non-arcuate configuration.
  • One leg of each of the members includes a series of cuts spaced along its length and extending from the free edge of the leg to the angle joining the legs. These cuts permit bending of the core protector to conform to the inner diameter of,the coil.
  • the cuts in the legs of one of the members- are offset with respect to the cuts in the other member such that when the protector is bent to conform to the inner diameter of the coil and the spacing along each cut correspondingly increases, i.e., the cut opens up when the protector is bent, there is nevertheless provided a section of paperboard material overlapping each cut.
  • the core protector thus provides protection for the material about the complete circumference, i.e. 360°, of the inner core of the coil.
  • 360° the complete circumference
  • the edges of the inner length of the material are protected from damage. No special locating or positioning of the C-hook, for example, is needed. Rather, since 360° protection to the edges of the material at the inner core is provided, the coil may be grasped at any location.
  • the protection it provides the coiled material including protection to the edges of the inner length of material around the entire circumference of the inner core, the economy of the materials of construction in that the protector is preferably formed of relatively inexpensive paperboard, the economic use of this material in that there is very little waste in forming the protector, the rigidity of the formed angular members whereby when the protector is placed in the core the flanges closely conform to the material and do not fall down or tend to flatten out, the fact that the angular members once bent tend to want to straighten out and thus when placed in the core the protector tends to urge itself into engagement with the inner diameter of the coil, and the fact that the protector can be economically packaged and shipped merely by stacking up a series of protectors one on another and shipping them in a straight or non-arcuate position. This results in full utilization of shipping capacity with no waste of space.
  • the invention also extends to a coil of material provided with interior core protectors in accordance with the invention.
  • a coil of sheet material 10 for example, a large and heavy coil of sheet steel of the type typically used in the automobile industry, for purposes of illustrating the environment in which this embodiment of the invention finds particular applicability.
  • the sheet material is coiled to form a large roll of material having a open centre, i.e. hollow, core 12.
  • a series of steel bands 14 are placed through the core 12 and about the coiled material to keep the material from uncoiling.
  • paperboard angle protectors 16 are provided on the outer diameter of the coil 10 to keep the edges of the sheet steel from cutting the steel straps.
  • An interior core protector 20 in accordance with the present invention is placed about the inner core 12 of the coil 10 on both sides of the coil, i.e., two protectors are used for each coil.
  • the protectors 20 form a protective barrier around both inner edges of the coiled material.
  • the core protector 20 is formed of two like overlapping formed angular members 22 and 24.
  • Each member 22 and 24 includes a pair of legs 22a and 22b and 24a and 24b, respectively, which are generally at right angles one to another.
  • the protector 20 is preferably formed of a relatively inexpensive material such as paperboard.
  • a presently preferred thickness of the protector is of the order of 0.30 cm, this being the total thickness of the protector or sum of the thicknesses of the two members 22 and 24.
  • One leg 22b and 24b of each member is die cut to provide a series of generally equally spaced cuts 26 extending from the outer edges 28 and 30, respectively, of each leg 22b and 24b to the angles 32 and 34, respectively, at which the two legs 22a and 22b and 24a and 24b of each member meet.
  • These die cuts 26 permit the protector to be bent into the generally circular configuration shown in Fig. 1.
  • the two members may be joined by an adhesive placed between the overlapping uncut legs 22a and 24a of the angles 22 and 24.
  • the protector 20 is about 190 cm long to cover the circumference of a 60 cm diameter core and each leg is approximately 7.5 cm long.
  • an area of protective paperboard extends axially in the interior of the core 7.5 cm from the outer edge of the coil from both sides of the coil and radially outwardly 7.5 cm along the face of each side of the coil 10.
  • the cuts 26 in one leg 22b of one member 22 are offset from the cuts 26 in the leg 24b of the other member 24.
  • the protector 20 is bent into its generally circular configuration and the width of the cuts 26 correspondingly widens, as shown in Fig. 3, there nevertheless is maintained at each cut 26 a section of protective material which overlies the openings caused by the cuts.
  • a section 22b underlies the cut 26 in leg 24, and a section 24b overlies the cut 26 in leg 22.
  • legs 22b and 24b are not glued together prior to bending of the core protector since the sections between the cuts 26 must be free to slide over their overlying sections to permit bending of the protector.
  • the core protector to the shape of the interior core of the coil: it is merely necessary to remove the release paper thereby exposing the pressure sensitive adhesive, bend the protector to its generally circular configuration, insert the protector in the coil, and tten press the legs 22b and 24b together.
  • the protectors 20 With the protectors 20 in place in the core 12, when the coil is grasped, for example, by a C-mook, or a hold down chain is thrown through the cor, protection of the edges of the inner length of the coiled material is provided about the full circumference of the inner core.
  • the core protector 20 provides for complete protection along the entire 360° circumference of the core, and the C-hook can therefore enter the core from any position about the core.
  • One of the advantages of the present embodiment is that when the protector 20 is bent to conform to the diameter of the core 12 the resiliency or memory properties of the paperboard material from which the protector is made tends to want to straighten the material back to its flat or unbend condition. This is desirable since it causes the protector to expand outwardly and, as a result, to tightly engage the material about the inner core. Thus, there is no need for any special provision for either locating or holding the core protector in position before strapping of the coil. Secondly, since the core protector is made of a formed angular paperboard member, the angle between the legs is rigid and maintains itself in both the unbent and bent conditions of the core protector.
  • the legs having the cuts 26 tend to lie flat against the surface of the coil as contrasted to falling down as would be the case if a flat material such as paper were only creased to lie against the face of the coil.
  • the core protector makes very economic use of this material. That is, there is no waste of material as would otherwise occur if the core protector were to be made as a annular piece. This would require cutting of an annulus out of a flat square sheet which would waste the core as well as the material lying outside the outer diameter of the annulus. Thus, a savings in material of the order 60% is realised with the core protector of the present embodiment.
  • the core protector can be packaged, shipped and stored in its flat or straight, i.e. unbent, condition (as'shown in Fig. 2) such that the core protector must be bent by the user to fit it into the coil.
  • This permits the protectors to be economically packaged and shipped merely by stacking them one on another. There is none of the wasted space which would be occasioned if annular protectors were shipped.
  • the core protector of the present invention provides not only excellent protection for the coiled material but is relatively economic to produce and to ship. Since these core protectors are a disposable item, this is very important to the producers of the coiled material.
