Abstract: A retractable stock guide has a stationary guide rail on which a retractable guide cap is operably supported. The guide rail and cap have two through holes at opposite ends through which two mounting studs extend to attach the stock guide to an associated die member. The holes in the guide cap are ovate, and the heads of the mounting studs are tapered, whereby tightening of the mounting stud shifts the guide cap relative to the guide rail from an aligned, retracted load/unload condition, to an inwardly protruding, extended run condition, wherein the stock strip is slidingly captured between two like stock guides and the mounting surface of the die. Two ball bearing guides can be substituted for the stationary guide rail.

Abstract: A crimping tool according to the invention includes a cylindrical C-5 carbide rod having a plurality of laser cut pyramid points on one end. An adapter sleeve is also provided for attaching the tool to an existing pneumatic press. The pyramid pattern on the end of the tool provides several unexpected benefits. First, the points engage the eyelet and prevent the tool from slipping off the eyelet during the crimping operation. Second, the crimps produced by the tool have a greater surface area than the conventional crimps, exerting more pressure on the wick core without shearing fibers. The pressure exerted on the wick is 25-35% greater than a conventional crimp. Further, the carbide material wears much slower than the conventional crimping tools. This assures a consistency in crimping over a long period of time. An exemplary embodiment of the crimping tool according to the invention is approximately 1.625 inches long and approximately 0.090 inches in diameter.

Any deviation between the sensed, or the actual worksheet position, with the desired worksheet position for each bend of the worksheet is compensated by further moving the worksheet, until there no longer is any discrepancy between the actual and the preprogrammed desired locations.
