In a device for feeding articles (21), cylindrical feed screws (35,36) having left and right hand pitched helical grooves (34,37) are arranged in parallel and are driven rotationally in opposite directions such that an article (21) deposited in the space between the roots of the grooves (34,37) at one corresponding end of the grooves (34,37) will be advanced axially to the opposite ends for exiting from between the feed screws (35,36).
