Abstract: This disclosure pertains to a press brake work piece alignment apparatus comprising an alignment shoe mounting plate adjustably secured to a supporting surface of a press brake adapted with a plurality of threaded holes transverse to the longitudinal axis of the forming dies. Bolts adjustably secure alignment shoes to the shoe mounting plate through longitudinal slots therein. One or more of the alignment shoes are hinged on a pivot axis transverse to the longitudinal axis of the forming dies, such that they can be selectively unfolded into a work piece alignment position for each sequential bending operation. Alternatively, a non-hingable alignment shoe may be utilized to initially position the work piece by locating a free edge thereof along the alignment edge of the alignment shoe. A calibrating scale assists in positioning the alignment shoes at predetermined locations upon the shoe mounting plate.
