ABSTRACT:
In punching, cutting and forming presses and the like, electronic detecting means and/or sensors are provided so as to trip the press and prevent an operation when a mal-function occurs such as a tear in the strip material or a mis-alignment or a mis-feeding of the strip. When the press is equipped with an elbow arrangement to permit adjustments for feed line height while maintaining feed cycle synchronization, then the arrangement must incorporate the automated locking device of the invention, the same automatically unlocking the swing plate simultaneously with the tripping of the press.
