Definitions

  • the present invention generally relates to the field of rolled sheet materials, and has to do particularly with a shielding device for protecting the upper, outer edges of such a roll during transportation.
  • the word “coil” will be used to designate a cylindrical bundle of sheet material. Such material is typically manufactured in the shape of an elongated rectangle, and may be rolled up over its length to form a thick-walled cylinder of overlapping layers or convolutions. When in the coiled form, the sheet steel is more manageable during transportation and handling.
  • a coil of sheet material is regarded as having an "exterior surface” (typically defining a circular cylinder), a “core” which is a hollow cylindrical passage at the centre of the roll, an “interior surface” which is the curved surface surrounding and defining the core, and “first and second ends” , referring to the two flat, parallel end surfaces of the coil where the side edges of the sheet can be seen.
  • first and second edges will refer to rolled material in close proximity to the interior surface and the first and second ends respectively.
  • the coil has an "axis" defined as a hypothetical line through the centre of the core, about which the rolled material was wound.
  • the "height" of the roll will refer to the distance between its first and second ends, the "interior diameter” will be the diameter of the core, and the “outside diameter” will be the diameter of the exterior surface.
  • Large heavy coils of sheet material are often transported on vehicles from one place to another. These coils are often bound with strapping which passes through the core, about the ends and over the exterior surface, in order to retain the coil integrity during handling. When the coils are loaded for transport, it is common to lay them on their exterior surface with the axis horizontal. The curvature of the exterior surface facilitates movement of the coils on the loading deck. Further, when the coils are lying on their exterior surface, loading cranes can insert a hook or bar into the hollow core to pick up the coils.
  • the coils are located on the deck of a vehicle, stops are wedged under the exterior surface to prevent them from rolling. Finally the coils may be fastened down with chains, or the like, that pass through the core and are secured to the deck at each end of the coil. The number of chains used to fasten the coil in place will depend upon the weight of the coil but it is common to have three or more chains that are secured forward, rearward and in line with the axis of the coil.
  • coils may be shaken and jostled.
  • the securing chains resist movement by pulling in an opposite direction against the interior surface of the core particularly about the edges.
  • frictional abrasion between the coils and the chains can cause gouging, bending and deformation due to chain tension and other damage that affects one or more layers of the coiled material from the interior surface outward.
  • there may also be telescoping of the coil where adjacent layers of the coiled material slide against one another in the direction of the axis of the coil. Telescoping can expose greater areas to damage from the chains, expose more material to the elements and create handling problems.
  • an edge protector having a cylindrical portion sized and configured so as to fit snugly within one end of the core of a coil, and further having a flat portion integrally connected to the cylindrical portion at an outer edge of the latter, and thence projecting substantially parallel to the end face of the coil in an outward direction.
  • the flat portion just mentioned is divided into a plurality of flat teeth, with each pair of teeth being separated by a slot which terminates in a rounded aperture located within the flat portion but relatively close to the junction location between the cylindrical and flat portions.
  • this invention provides an edge protector for a coil of sheet material, comprising: an integral body defining a part-cylindrical collar portion having at least one arcuate edge, the collar portion being adapted to lie in protective juxtaposition against an edge of the outermost convolution of a coil of sheet material, and a substantially flat portion having an outer boundary adjoining the collar portion at said arcuate edge, the substantially flat portion lying substantially in a plane to which the axis of said part-cylindrical collar portion is substantially perpendicular, and having an inner boundary spaced inward from said outer boundary, said substantially flat portion exhibiting a plurality of slots spaced peripherally apart around the flat portion between the peripheral extremities of the flat portion, the slots extending radially outward toward said outer boundary, and terminating at locations spaced inward away from the outer boundary.
  • this invention provides a method of securing in place a coil of sheet material, the coil having an open core, the method comprising the steps: a) providing an edge protector which has an integral body defining a part-cylindrical collar portion having at least one arcuate edge, the collar portion being adapted to lie in protective juxtaposition against an edge of the outermost convolution of the coil of sheet material, and a substantially flat portion having an outer boundary integrally connected to the collar portion at said arcuate edge, the substantially flat portion lying substantially in a plane to which the axis of said part-cylindrical collar portion is substantially perpendicular, and having an inner boundary spaced inward from said outer boundary, said substantially flat portion exhibiting a plurality of slots spaced peripherally apart around the flat portion, between the peripheral extremities of the flat portion, the slots extending radially onward toward said outer boundary, and terminating at locations spaced inward away from the outer boundary; b) situating the coil with its axis horizontal, c) placing the edge protector adjacent a top
  • Figure 1 is a perspective view of a coil edge protector in accordance with one embodiment of this invention:
  • Figure 2 is a perspective view of a second embodiment of this invention, showing a coil to which two edge protectors have been applied;
  • Figure 3 is a perspective view of a variant, in which cylindrical portions of two protectors are of increased size, so that a chain or the like can be tightened over the curved top of the coil, with the collar portion sandwiched between the chain and the coil.
  • Figure 1 shows in perspective an edge protector for a coil of sheet material.
  • the edge protector exhibits an integral body generally shown at 10, the integral body defining a part-cylindrical collar portion 12, and a substantially flat portion 14.
  • the part-cylindrical collar portion 12 has a first arcuate edge 16, and a second arcuate edge 18.
  • the two edges 16 and 18 are substantially identical in curvature, and lie in spaced-apart parallel planes.
  • the collar portion 12 is adapted to lie in protective juxtaposition against an edge of the outermost convolution of a coil of sheet material.
  • a handle 19 is defined by the provision of an opening 19a, which is elongate in the direction of the arcuate edge 16.
  • the substantially flat portion 14 has an outer boundary 20 adjoining the collar portion 12 at the upper arcuate edge 18.
  • the substantially flat portion 14 lies substantially in a plane to which the axis of the part-cylindrical collar portion 12 is substantially perpendicular.
  • the flat portion 14 defines a plurality of slots 22 spaced peripherally apart around the flat portion 14 and extending radially outward toward the outer boundary 20.
  • the slots 22 converge (taper inward) as they proceed toward the outer boundary 20.
  • the slots terminate at locations spaced inward away from the outer boundary 20. More specifically, each slot terminates in a rounded opening 24, preferably circular, which is spaced inward away from the outer boundary 20.
  • the slots 22 are so wide at their commencement (i.e., the end remote from the boundary 20) that they can be regarded as defining, by themselves, an inner boundary opposed to the outer boundary 20.
  • a coil 30 is positioned with its hypothetical axis 32 vertical.
  • two opposed edge protectors 10 in the configuration of Figure 2, it is possible to secure the coil 30 in place by passing chains or the like across the upper face, as shown at 34. Both ends of the chain 34 (only one visible) are secured by suitable connectors (not shown) to the surface supporting the coil.
  • suitable connectors not shown
  • Figure 3 shows a coil 38, situated with its central axis 40 horizontal.
  • An edge protector 10a at the bottom of the coil 38 protects the coil from flattening and other distortions due to the fact that the weight of the coil is pressing against the supporting surface within a very small area (hypothetically a line contact, but in practice some flattening would normally occur, so that the weight of the coil would be somewhat distributed).
  • the arrangement of the lower coil protector 10a in Figure 3 largely protects the coil from flattening and other distortions at the bottom point of contact with the supporting surface.
  • a further coil protector 10b At the top of the coil 38 there is a further coil protector 10b, essentially identical to the protector 10a at the bottom.
  • Both of these protectors 10a and 10b have a part-cylindrical collar portion 42, which is wider than the corresponding portion 12 in Figure 2.
  • the reason for the greater width of the collar portion 42 is to allow a chain or the like 44 to be looped over the coil 38 and tied down angularly at either end (as indicated by the arrow heads 46 in Figure 3), without the risk that the collar portion 12 would slip out from under the chain 44.
  • a further chain 50 could be passed through the centre core 48 of the coil 38 and then tightened around the two ends of the core 48, with an edge protector 52 in place at each end (to protect the internal convolutions of the coiled material), the chain 50 then extends downward at an angle to a securement location on the supporting surface.
