Abstract

The present invention relates to a pallet comprising first and second base parts (A1 and B1), each folded from pieces of corrugated, waterproof fiber material, for instance paper. Rectangular pieces (A, B) are cut from rolls of fiber material and the two base parts are made by notching and folding the pieces according to separate sequences. The first base part (A1) is put into the second base part (B1) and beams (31) on the second base part are folded in under the first base part and constitutes the feet of the pallet. The beams have longitudinal, v-shaped inner stiffeners (21, 22). All surfaces and points on the two base parts in contact with each other are glued and all open edges on ends and openings are provided with waterproof layers.

Claims

1. A pallet comprising at least two base parts made of corrugated fiber sheets, wherein a first rectangular piece, having a longitudinal corrugated layer with opposed long sides and short sides between an upper side and an under side and a width that after a first folding sequence forms a first base part symmetrical to a center line, is divided into 14 parts by fold lines of which the three first are made from the upper side, the fourth from the under side, the fifth and sixth from the upper side, the seventh from the under side, the eighth and ninth from the upper side, the tenth and eleventh from the under side, the twelfth and thirteenth from the upper side and the fourteenth from the under side, whereby the first piece, when folded at the fold lines, from the short sides towards a first center line, forms the first base part with three adjacent channels with rectangular cross-section at each end and a height preferably equal to half the height of the pallet and two adjacent channels with the same rectangular cross-section on each side of the first center line and spaces between the three adjacent channels and the two adjacent channels permit positioning of a fork on a fork lift truck, wherein a second rectangular piece having a longitudinal corrugated layer between an upper side and an under side and a width equal to the length of the pallet and after a second folding sequence forms a second base part, symmetrical to a second center line, said second rectangular piece is divided into 7 parts by fold lines of which the first fold lines are outer fold lines made in the under side and the other fold lines are in the upper side and wherein a distance between the two inner most pair of fold lines on either side of the second center line is equal to the width of the pallet and having rectangular openings with width, height and length and a distance to each other equal to the spaces in the first base part, whereby the second piece, when folded along the fold lines, from the ends towards the center, forms the second base part having longitudinal beams at each end with interior stiffeners formed by first and second parts, wherein the first base part is laid into the second base part with the longitudinal beams under the long sides of the first base part and the inner most part of the second piece outside the long sides so that the edges coincide, and the rectangular openings coincide with the spaces in the first base part and the longitudinal beams are in contact with the under sides of the channels of the first base part and support the pallet, and contacting surfaces and contacting points within and between the base parts are glued.

2. A pallet according to claim 1, wherein the first base part comprises two symmetrical parts made by folding the fourteen parts and the fourteenth parts are glued together.

3. A pallet according to claim 1, wherein the fiber sheets and all open cut surfaces are coated with waterproofing layers.
