Abstract: A method of making double reverse corrugated material includes feeding the material between an upper die and a lower die. Each of the dies have laterally spaced projections and a stripper positioned in the spaces between the projections of the die. One die is moved toward the other die to form the corrugations in the material. One die is moved away from the other die while both strippers and the other die are maintained substantially fixed with respect to each other. The stripper associated with the moving die is then moved with respect to the other die and the stripper associated with the other die is then moved with respect o the other die to strip the formed double reverse corrugated material from the dies. The formed material is then moved out from between the dies.

Abstract: An improved high strength wrench is stamped from a strip of a heat hardenable and relatively strong metal, such as stainless steel. The wrench is of the open-end type and has jaws with operating surfaces which, due to the hardness of the metal from which the wrench is stamped, maintain their original configuration even after the wrench has been utilized for an extended period of time. To promote the accurate formation of the operating surfaces of the jaws of the wrench, they are initially formed to a size which approximates their final size and configuration. The operating surfaces are then accurately trimmed to their final size and configuration by a shaving operation. During this shaving operation, a section of metal extending between the outer ends of the jaws of the wrench holds the jaws of the wrench against movement relative to each other.
