Definitions

  • This invention relates to a method of packaging a stack of sheet material.
  • stack of sheet material is meant a pile of rectangular sheets of material in register.
  • a method of packing a stack of sheet material which comprises applying to both the top and bottom faces of the stack an element which comprises a flat base sheet of rigid material of length and width slightly smaller than the sheet of material and upstanding walls on two adja cent sides of the base sheet, said walls being of less height than the stack, and binding the resultant pack with bind ing material so as to urge the upstanding walls of the two elements into close contact with the sides of the stack.
  • the two elements used in the method of the present invention are of similar dimensions but one may be smaller than the other.
  • a single band of strapping material may be used which is placed around the four upstanding walls, and then drawn tight so that it is under tension or there may be two tension bands crossing over two other tension bands at right angles, each band extending over two other tension bands at right angles, each band extending over both of the base sheets.
  • the binding material may be composed, for example,
  • the stack of sheet material can not buckle due to the presence of the base sheets of rigid material on each side of the pack.
  • rigid material is meant material which cannot easily bend, for example wood, thick cardboard or some plastic materials such as polystyrene or copolymers of acrylonitrile-butadiene-styrene known as ABS material.
  • the whole pack i.e. the stack of sheet material with the two elements in position
  • the sleeve shrinks and tightly binds round the pack on all sides urging the upstanding sides of the elements towards each other and thus pressing tightly against the stack of sheet material from all four sides, in the same way as the bands of strapping material.
  • the stack of sheet material is placed initially in a light-tight folder such as a polyethylene bag.
  • FIG. 1 shows the front and back elements used for packing a stack of sheet material.
  • FIG. 2 is a perspective view of a stack of sheet material showing the front and back elements held in position by bands of strapping material.
  • FIG. 3 is a perspective view of a stack of sheet material showing front and back elements in position, the stack being in a sleeve of polyethylene.
  • FIG. 4 is the same stack of sheet material after the sleeve of polyethylene has been heat-sealed on to the stack.
  • FIG. 1 is a perspective view of front and back elements as used in the present invention.
  • element 2 comprises three parts, a base sheet 4, one upstanding wall 5 and a hidden upstanding wall 5A which is shown in outline.
  • element 3 comprises a base sheet 3A and two side walls 6 and 7.
  • FIG. 2 a stack of sheet material 1 is partially enclosed by the two elements 2 and 3, of element 2 the base sheet 4 and one upstanding wall 5 are shown; of element 3 the two upstanding walls 6 and 7 are shown. Holding the pack together are four bands of polypropylene 8-11 under tension.
  • FIGS. 3 and 4 the numbers denote the same parts as in FIGS. 1 and 2, but in the case of these figures there are no hands of polypropylene; the pack in FIG. 3 being totally enveloped in a sleeve of polyethylene 14 which has two open ends 15 and 16.
  • a method of packing a stack of sheet material to prevent relative movement between the sheets which comprises applying to both the top and bottom faces of the stack an element which comprises a flat base sheet of rigid material of length and width slightly smaller than the sheet of material and which has upstanding walls on two adjacent sides of the said base sheet, said walls being of less height than the stack, binding the resultant pack with binding material so as to urge the upstanding walls of the two elements into close contact with the sides of the stack and thus disable the stack of sheet material from being flexed during transportation.
  • binding material comprises bands of polypropylene.
  • binding material is a sleeve of heat-shrinkable material.
  • a pack of sheet material free from relative movement between the sheets which comprises a stack of sheet material which has on both the top and bottom faces of the stack an element which comprises a fiat base sheet of rigid material of length and width slightly smaller than a sheet of material and which has upstanding walls on two adjacent sides of the base sheet, said Walls being of less height than the stack, the four said upstanding side walls partially covering the four sides of the stack of sheet material, the two said elements being held in position on the stack by binding material such that flexion of said stack is prevented during transportation.
  • a pack according to claim 7 wherein the binding material comprises bands of polypropylene.
  • a pack according to claim 7 wherein the binding material is a sleeve of heat-shrunk material.
