The feeder consists of driven rollers which carry a pallet stacked with various parts for the press underneath a plate with suction vents. These collect the parts and move them vertically until they adhere to the lower part of a conveyor belt. The suction plate is moved by a vertical cylinder solid with a supporting structure, under which is a line of driven rollers, and which includes a number of guides for other piston rods carrying suction vents, and a stop in the upper part to limit its return downwards. A helical spring surrounds the part of the piston rod below the suction plate, to keep the stop against the plate. (1)
