Abstract
A machine for setting eyelets and the like in printed circuit boards includes a generally U-shaped frame having a pair of spaced-apart support arms defining a workpiece receiving zone therebetween, a first tool movably mounted in one of the support arms, and a second tool fixedly mounted in the other support arm and axially aligned with the first tool. An adjustable torque screw is connected to the first tool for moving the first tool into aligned contact with the second tool at a pre-determined eyelet setting pressure. The adjustable torque screw insures that the eyelet setting pressure does not exceed the pre-determined eyelet setting pressure despite continued rotation of the adjustable torque screw.
