Abstract
A support structure for supporting a load comprises a core of connected paper strips including spacer strips of corrugated paperboard and at least one bent strip having a plurality of laminated paper layers. The bent strip is disposed between opposing spacer strips and secured at bend surfaces along the bent strip. The bent strip and the opposing spacer strips have edge surfaces for supporting the load. The edge surfaces define a plane substantially perpendicular to the bend surfaces. The bent strip is preferably corrugated paperboard or chipboard. The opposing spacer strips may be substantially parallel, curved, or any combination of the two to provide a variety of desired shapes. The bent strip may be creased at substantially equal intervals to form bend surfaces along opposite sides of the bent strip. An adhesive is applied along the bend surfaces for securing the bent strip to opposing spacer strips and for holding the bent strip at a predetermined pitch angle. A cover may be wrapped around a substantial portion of the core for further reinforcing and restricting movement of the strips. The cover is preferably adhesively secured to the core.
