Abstract

A unit of the cardboard pallet is formed by a single piece of cardboard. First, the two side portions are folded up towards the centerline. Then, the cardboard piece is folded up along the centerline. Next, the two end portions are folded outwards to a right angle. Now, a unit with a “T” shaped cross section and an enhanced strength is formed.

Claims (6)

1. A folding method for cardboard pallets, comprising the following steps:

(1) cutting up a single piece of cardboard to a shape having two symmetrical side portions along a centerline;

(2) folding the two side portions towards the centerline to form two symmetrical dual-layered side portions;

(3) folding up the cardboard piece along the centerline; and

(4) folding two entirely dual-layered end portions of the two symmetrical dual-layered side portions outwards to a right angle to form a unit with a “T” shaped cross section and with its vertical part comprised of four layers of cardboard and its two top parts respectively folded onto two sides of the vertical part comprised of two layers of cardboard.

2. The folding method as in claim 1 , wherein a portion of the cardboard is cut up and removed in the cutting process so that a slot is formed when the unit is folded up.
