<p>The device controls the upper mechanism of the positioning pieces, the sheet layer and the opening mechanism of the gripper of sheets of paper from the outlet of a feed table. It comprises a horizontal axle (30) which rotates cyclically through a predetermined angle. The mechanism has, parallel to and near each side wall of the feed table frame, a lever (60) rotating about an axle (61) near its upper front end. The lever rear end carries a wheel (62) resting on the segment of a cam (22) of the cam lever (20). Each lever is pulled from a fastener (65), located at about a third of its lower edge, downwards by a spring (66). The spring lower end is fixed to a fastener (67) of the frame side wall. The upper edge of this lever carries a locking wheel. <IMAGE></p> |
