<p>Single sheets (1) of paper are separated automatically from a stack (P) into reams (5), already divided by markers (2), exploiting the frictional properties of a pressure element (7) which is mounted to the end of an arm (8) associated with an actuator (9) and capable of movement in a direction angled upwardly and toward the front face (A) of the stack (P). The upward motion of the arm (8) causes the pressure element (7) to impinge on the underside of the topmost marker (2), which is bent upwards and flattened against the vertical face of the first and topmost ream (5); as the arm extends further, the corresponding edge of the ream is raised forcibly under the lifting action of the marker (2) induced by the pressure element (7), at which point the sheets can be engaged and pushed sideways by a set of blades (6) advancing on a level separated from the topmost surface of the stack (P) by a distance (H1) equivalent to the height (H) of the ream (5). <IMAGE></p> |
