  • means for sensing a selected press cycle phase of said press;

    means for engaging stock material adapted to be fed by said press feed to said press; and

    release means capable of infinite variation during the feeding of said stock material to said press connected to said means for engaging stock material and communicating with said sensing means, said release means being operable to move said means for engaging stock material in a first direction relative to said stock material responsive to detection by said sensing means of the onset of said selected press cycle phase to cause separation of the means for engaging from said stock material and for moving said means for engaging stock material in a direction generally opposite said first direction responsive to detection by said sensing means of the termination of said selected press cycle phase to cause the means for engaging to reengage with said stock material.
