Apparatus for transporting sheet metal plates from a supply source and positioning the plates at a plate shearing table includes a carrier capable of horizontal transport. A device is secured to the carrier for effecting up and down and turning movement. A gripper member is mounted on the device and moves with it. The gripper member includes at least one electromagnetic plate with an annular sealing lip in the surface of the plate. In combination with the surface of the plate, the sealing lip forms a suction space connected to vacuum producing equipment. A switch controls the electromagnetic plate and a control valve operates the vacuum producing equipment with the switch and control valve arranged in a parallel switching network.
