ABSTRACT:
A device for discontinuously advancing stock or work along or in discontinuously operating production machinery, a press for example. The stock or work is gripped by grips distributed along parallel and separated rails. The grip-supporting rails extend in the direction the stock or work advances in. The rails have three different motions, specifically back and forth together in the direction the stock or work moves in, together and apart transversely at at least one essentially right angle to that direction, and up and down together. A separate drive mechanism discontinuously governs each motion. The separate drive mechanisms are positioned essentially symmetrical to and below the rails. The drive that moves the grip-supporting rails together and apart accommodates at least one spindle that is engaged by a motor. The drive that moves the rails up and down accommodates at least one spindle that is engaged by another motor. The together-and-apart and up-and-down motions are derived from blocks that travel back and forth along the spindles without tilting and across the direction the stock or work advances in.
