Abstract: For distributing annular workpieces onto a plate provided with a plurality of bolts protruding from the plate surface, each to hold and arrest a correctly positioned workpiece, there is provided a magazine which accommodates a plurality of workpieces in contact with one another at their peripheral surfaces, the magazine being inclined at an angle with respect to the plate surface, being relatively displaceable in the direction of its inclination parallel to the plate surface, and being provided at its lower end with a resilient holding device for the individual release of one workpiece at a time.
