ABSTRACT:
A crimping device constructed with a plurality of shares bent in a middle section with offset pairs of jaws mounted thereon. The bent shape of the shares allows offsetting the opposing rows of jaws so that they overlap without interference. This means that each of the jaws can be identical in conformation. When closed on a seal, the crimping device creates a staggered pattern of multiple crimps so that a maximum interior surface area of the seal is pressed into the band being sealed. The working surface of the shares is shaped as an arch so that when used in conjunction with the uniquely shaped working surfaces of the jaws, the device causes the seal to be arched upward during the crimping operation. This arching further increases the rigidity and holding strength of the seal to be formed.
