Abstract:
1. Process for 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 stiffners 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 projection ( 12 ), characterized in that production takes place in a pallet assembly machine ( 1 ) in that a folded load deck ( 3 ) is produced from at least one flat sheet ( 5 ) provided with bends ( 9 ) by folding of the sheet ( 5 ) at set bends ( 9 ), which are to be arranged in the corners of the recesses ( 22 ), a first bend ( 9 ) between two of the sides ( 13 , 15 ) of the projections ( 22 ) being folded so that first projection creases ( 12 ) are formed, that a number of base beams ( 4 ) are placed in a prefixed position to the load deck ( 3 ) thus folded forming a preferred pallet ( 2 ), the projection creases ( 12 ) first being brought into position inside the respective recesses ( 22 ), following which the remaining bends ( 9 ) of the projection ( 12 ) are pressed into the recesses ( 22 ) so that the projections ( 12 ) acquire the aforesaid essentially primsatic shape and due to which the projections ( 12 ) are permanently fixed in the recesses ( 22 ) due to the contact obtained between all sides ( 13 , 15 , 16 ) of the projections ( 12 ) and said recesses ( 22 ).
