Abstract
An installation for feeding sheet-metal blanks to a first working stage of a multi-stage press, in which the blanks fed individually by way of a suspension conveyor into the area of an intermediate deposit station are to be transferred to active gripping devices attached at the transfer rails. For avoiding standstill periods of the transfer rails during the closing of the active gripping devices, the blank is lifted during the lifting of the transfer rail synchronously therewith. A carriage adapted to be lifted and lowered serves for that purpose which is synchronized by way of a crank drive at least in the lifting phase of the transfer rails with the lifting-lowering drive of the transfer rails.
