ABSTRACT:
Gaging apparatus for a metal forming machine having a gage bar which is pivotable about a central longitudinal axis of the bar and which is maintained in a normal position by a spring mechanism. In the presence of an upward force applied to the bar, the bar will pivot upwardly, and upon removal of the upward force, will be returned by the biasing action of the spring mechanism to its rest position. A switch can be associated with the gage bar for actuation during upward movement of the bar to provide a control signal to the gage positioning system to cause withdrawal of the bar away from the metal being formed.
