<p>The invention relates to a process and an apparatus for the production of pallets ( 2 ), which are assembled from several base beams ( 4 ) and at least one load deck ( 3 ), which is folded to form a deck level ( 10 ) comprising essentially prism-shaped stiffeners in the form of deck projections ( 12 ), which load deck ( 3 ) is anchored to the base beams ( 4 ) in that the projections ( 12 ) are inserted into recesses ( 22 ) in the base beams ( 4 ), which recesses ( 22 ) have essentially the same shape as the outer cross-section of the projections ( 12 ). According to the invention, production takes place in a pallet assembly machine ( 1 ) in that the folded load deck is produced from at least one flat sheet ( 5 ) provided with bends ( 9 ) by folding of the sheet at set bends, which are to be arranged in the corners of the recesses, a first bend between two of the sides ( 13, 15 ) of the projections being folded so that first projection creases ( 12 ) are formed, that a number of base beams are placed in a prefixed position to the load deck thus folded forming a prefixed pallet, the projections creases first being brought into position inside the respective recesses, following which the remaining bends of the projection are pressed into the recesses so that the projections acquire the aforesaid essentially prismatic shape and due to which the projections are permanently fixed in the recesses due to the contact obtained between all sides ( 13, 15, 16 ) of the projections and said recesses. The invention also relates to a pallet, a blank for a base beam or load deck included in the pallet and a pallet unit consisting of two or more load decks included in the pallet, which are produced according to a process or in a pallet assembly machine according to the invention.</p> |
