Abstract
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.
