This invention provides a feed system comprising a base on which a portion of the article being fed rests. The base extends along a feed path for the article. The feed system also includes at least one rotatable feed screw lying in an axis parallel to the feed path. The feed screw includes an entry end, a discharge end and a continuous, helical groove having a profile for receiving a portion of the article being fed. The feed system includes a linkage device for transferring reciprocating motion of a reciprocating press into which the articles are fed into rotary motion of the feed screw, and a feeding device for feeding articles into the groove at the entry end. The feed system also comprises a cooperating second screw or a resilient guide bar, for maintaining the article within and along the feed path as the feed screw is rotated.
