A method of manufacturing pallets from sheets of substantially the same dimensions as the dimensions of the pallets to be manufactured by the steps of sequentially feeding sheets of a predetermined polygonal shape, cutting substantially at one time a plurality of corner portions of the thus fed sheets to obtain pallets and then discharging the thus obtained pallets. Belt conveyors sequentially feed sheets of a predetermined polygonal shape and cutting dies cut substantially at one time the rear corner portions of the preceding sheet and the front corner portions of the following sheet to obtain pallets and belt conveyors sequentially discharge the thus obtained pallets. When a ruled line, that is, an elongate recess or the like for bending is needed in the resulting pallets, cutting of the corner portions and formation of the ruled line are effected substantially at one time.
A method of manufacturing pallets from a plurality of sheets, said sheets having a predetermined polygonal shape and dimensions substantially the same as the dimensions of the pallets to be manufactured, said plurality of sheets comprising a first sheet, a second sheet and at least a third sheet;
A method of manufacturing pallets comprising the steps of 1) sequentially feeding a plurality of sheets, said plurality of sheets comprising a first sheet, a second sheet and successive sheets, said plurality of sheets having a predetermined polygonal shape and dimensions substantially the same as the dimensions of the pallets to be manufactured, 2) cutting substantially at the same time not less than one rear corner portion of the first sheet and not less than one front corner portion of the second sheet to obtain pallets, sequentially discharging the thus obtained pallets and repeating said steps 1) and 2) with said successive sheets.
An apparatus for manufacturing pallets comprising:
An apparatus for manufacturing pallets comprising feeding means for sequentially feeding a plurality of sheets having a predetermined polygonal shape and substantially the same dimensions as the dimensions of the pallets to be manufactured, cutting means for cutting substantially at the same time not less than one rear corner portion of a first sheet and not less than one front corner portion of a second sheet to obtain pallets, discharging means for sequentially discharging the thus obtained pallets.
