ABSTRACT:
Apparatus for dividing a single row of articles into two rows comprises a pair of complementary closely spaced parallel screws arranged to receive a single row of articles from an infeed conveyor so that alternate articles are engaged by the thread of each screw and moved laterally into the groove of the other screw to form two rows of articles, the thread of one screw being cut away at the outfeed end thereof, an outfeed conveyor arranged to receive articles from the outfeed end of the screws and to move the articles at a velocity approximately one-half the velocity of movement of the articles longitudinally between the screws so that the two rows of articles are automatically aligned transversely, and a dead plate interposed between the infeed and outfeed conveyors.
