Abstract

This invention is addressed to a new and improved method for automatic precision feeding of high speed presses for mechanically working metal strips in which the metal strip is fed to the press in a precise longitudinal position relative to the die stamp with recovery of elongation due to the effect of the die stamp wherein the strip is gripped between the jaws of at least two movable grips, one above the press and the other below the press in the direction through which the strip is advanced, whereby the movable grips are displaced to advance the strip and the strip is then gripped by at least two fixed grips, one above and another below the press, while the movable grips are displaced to their starting position in which the fixed grips below the press open before the movable grips close while the fixed grip above the press opens as the movable grips have closed to permit recovery of the elongation of the strip.
