Abstract

A fiberboard sheet is provided comprising a surface protector with a plurality of embedded creases wherein each of the creases can be folded in order to position a portion of the fiberboard sheet horizontally and another portion of the fiberboard sheet vertically. The fiberboard surface protector provides for quick and easy folding of the fiberboard sheet, along a multitude of crease lines, to allow for simultaneous horizontal and vertical protection within a single product. The fiberboard surface protector eliminates the need for two or more separate products and extra steps in the protection process. The fiberboard surface protector creates a seamless barrier between a horizontal and a vertical junction of orthogonally adjacent surfaces.

First claim

What is claimed is:

1. A method of making a surface protector to protect selected portions of at least two adjacent surfaces, the method comprising:
providing a fiberboard sheet of foldable material having a perimeter;
scoring a top surface of said fiberboard sheet to include a plurality of creases aligned generally parallel to at least two sides of said sheet, said step of scoring performed by a device applying up to 80 psi of pressure to said top surface of said fiberboard to form each of said creases;
positioning each said crease offset from said side at a different location than another said crease, each of said creases having a constant width and depth along a length of said crease;
wherein said creases are water resistant;
folding said sheet along at least a first crease thereby creating a first portion and a second portion of said sheet on either side of said first crease;
wherein said first portion of said sheet protects a first surface and said second portion of said sheet protects a second surface; and,
wherein said first surface is generally orthogonal to said second surface.

2. The method as defined in claim 1 , further comprising:
using a metal pneumatic powered wheel for perforating said fiberboard sheet for said scoring of said plurality of creases.

3. The method as defined in claim 1 , further comprising:
using a pneumatic powered wheel for scoring said fiberboard sheet including said plurality of creases.

4. The method as defined in claim 1 , wherein said scoring includes a depth from about 10% to about 20% of a depth of said fiberboard sheet.

5. The method as defined in claim 3 , wherein said pneumatic powered wheel includes a pressure from about 40 psi to about 50 psi.

6. The method as defined in claim 1 , wherein said creases include a width from about ¼ inch to about ½ inch.

7. The method as defined in claim 1 , wherein said plurality of creases includes three (3) creases;
a first crease is aligned with a first side of said sheet and offset at a distance from about 4 inches to about 12 inches;
a second crease is aligned with a second side of said sheet and offset at a distance from about 1 inch to about 6 inches; and,
a third crease is aligned with said second side of said sheet and offset at a distance from about 7 inches to about 18 inches.

8. The method as defined in claim 1 , wherein said plurality of creases includes four (4) creases;
a first crease is positioned from about 4 inches to about 12 inches from a first side of said sheet;
a second crease is positioned from about 4 inches to about 12 inches from a center line of said sheet;
a third crease is positioned from about 1 inch to about 6 inches from a second side of said sheet; and,
a fourth crease is positioned from about 7 inches to about 18 inches from said second side of said sheet.

9. A method of making a floor surface protector to protect selected portions of at least two adjacent surfaces of a floor surface, the method comprising:
providing a fiberboard sheet of foldable material having a perimeter, said fiberboard constructed of a water resistant material;
scoring only a top surface of said fiberboard sheet to include a plurality of creases aligned generally parallel to at least two sides of said fiberboard sheet, each of said creases in said fiberboard sheet has a depth of about 5% to about 30% of a depth of said fiberboard sheet, said depth of each of said creases is constant along a length of said crease, each of said creases includes a width of about ¼ inch to about ½ inch, each of said creases having a constant width along a length of said crease, said step of scoring including using a wheel for forming said scoring on said fiberboard sheet, said wheel applying 20 psi to 80 psi of pressure to said top surface of said fiberboard to form each said creases;
positioning each said crease offset from said side at a different location than another said crease;
wherein said creases are water resistant;
folding said fiberboard sheet along at least a first crease thereby creating a first portion and a second portion of said sheet on either side of said first crease, said crease configured such that during said folding step said crease does not tear or separate and maintains its water resistance;
placing said folded fiberboard sheet on said floor surface;
wherein said first portion of said sheet protects a first surface of said floor and said second portion of said sheet protects a second surface of said floor; and,
wherein said first surface is generally orthogonal to said second surface.

10. The method as defined in claim 9 , wherein said wheel applies a pressure of about 40 psi to about 50 psi to said top surface of said fiberboard sheet to form said creases.

11. The method as defined in claim 10 , wherein said plurality of creases includes three (3) creases;
a first crease is aligned with a first side of said sheet and offset at a distance from about 4 inches to about 12 inches;
a second crease is aligned with a second side of said sheet and offset at a distance from about 1 inch to about 6 inches; and,
a third crease is aligned with said second side of said sheet and offset at a distance from about 7 inches to about 18 inches.

12. The method as defined in claim 11 , wherein said wheel is a pneumatic powered wheel.

13. The method as defined in claim 10 , wherein said plurality of creases includes four (4) creases;
a first crease is positioned from about 4 inches to about 12 inches from a first side of said sheet;
a second crease is positioned from about 4 inches to about 12 inches from a center line of said sheet;
a third crease is positioned from about 1 inch to about 6 inches from a second side of said sheet; and,
a fourth crease is positioned from about 7 inches to about 18 inches from said second side of said sheet.

14. The method as defined in claim 13 , wherein said wheel is a pneumatic powered wheel.
