Abstract: A machine for assembling screw blanks and washers includes a rotatable feed disc which continuously feeds washers in succession along a first path, the feed disc having a plurality of notches formed around the periphery thereof, each notch intended to receive a single washer. A rotatable turret continuously conveys screw blanks in succession along a second path in a plane parallel and vertically above the first path. The turret and feed disc are continuously rotated in opposite directions and in timed relationship such that screw blanks are conveyed in timed relationship to the feed of washers such that each screw blank is in turn brought into axial alignment with a respective washer. The turret includes a plurality of circumferentially spaced clamping heads each of which receives and clamps an individual screw blank.
