Abstract (en)
[origin: US6904659B1] Method for production of an eyelet, during connection of workpieces where material of an outermost workpiece is pulled through openings in the other workpieces, using a single feed movement of rim hole or eyelet punch to both shape the eyelet from the one workpiece and generate the openings, in the other workpieces by breaking out one or more pieces of materials, providing a reduction in the number of operating steps and simplifying such steps.
