Stacking device

A stacking apparatus (20, 40) comprising a rotatable stacking wheel (10) with a multiplicity of fingers (14), of which one end (13) is fastened on the circumference of a hub (12), enclosing a stacking-wheel spindle (26), and between which there is formed in each case one receiving gap (16, 16′) for sheet-like articles (22), it being the case that the width of the receiving gap (16, 16′) can be adjusted, in dependence on the angle position of the stacking wheel (10), between an open position, in which the sheet-like articles (22) can be introduced into the gap, and a position in which the sheet-like articles (22) are retained, characterized in that the hub (12) together with the fingers (14) is produced in a single piece by injection molding from plastic, in particular carbon-fiber-reinforced polyethylene, and is designed as an elastically deformable ring (12) which is circular in the state in which it does not have any external forces acting on it, and the ring (12) is mounted rotatably on a ring former (24, 42) which brings the ring (12) into a non-round, in particular oval shape, there being an increase in the size of the receiving gap (16′) between fingers (14′) of which the fastening end (13) on the ring (12) passes into a region in which the ring (12) assumes a radius of curvature (D2) which is smaller than its circular shape, and a decrease in size of said receiving gap as it leaves said region.
