Abstract
A duplex feeder having two separate complementary stock feeding units each having its own independent semi-automatic control circuit, these two separate control circuits being alternately operated by a demand feed signal generating means that is adapted to be responsive to the successive operative cycles of the press with which the feeder is to be used whereby a first operative cycle of the press causes just a first one of said feed units to move through a feed-index cycle of movement so as to advance the stock through a first incremental feed step and whereby the next operative cycle of the press causes just the second one of said feed units to move through a feed-index cycle of movement so as to advance the stock through its next incremental feed step. Also provided for the feeder is a buffer system wherein the normal exhaust flow conditions for each of the two main fluid motor means for the two feed units respectively is modified in response to the terminal portion of the feed stroke of each of the two feed slides of said feed units so as to thereby cause said main fluid motor means to afford a cushioning action during the arresting of each of said feed slides during the terminal portions of the successive stock feed strokes thereof.
