The apparatus erects flat die-cut blanks having longitudinal (2a-d) and transverse (3) creases and longitudinal slots (4) into rectangular section tubular box elements. Suckers 14 on a pivoted member 15 pick a blank (1) from the bottom of an overhead pile held in a vertical store 9, and pull it downwardly causing a wire brush 25 or rubber flaps to pull the top of the tube upwardly as the member 15 descends. <IMAGE> |
