Abstract

An apparatus for taking flat erectable blanks out of a magazine and transferring them to a conveyor apparatus has a rotor, on the circumference of which suction cups are distributed, offset uniformly. The rotor is rotatably supported as a planet part in a rotating planet carrier and upon revolving is additionally rotated about its shaft by a planetary gear. In this process the suction cups travel over a self-contained cycloid path (C) having four reversal points (F, G, H, I) and intervening concave arcs. For acting upon the articles, for instance pressing on a foldable box or rotating it about a transverse axis, a cam disk is rotatable supported on the shaft of the rotor and is hindered from rotating with the rotor by being coupled to a rocker arm supported in stationary fashion. A lever guided by a roller in the cam race acts upon a pivotable pressing prong or upon the rotatably supported suction cup.
