A sheet stacker includes a lifting table mounted along the axis of the stacker, driving carriages located symmetrically relative to the table with possibility of displacement in the direction perpendicular to the axis of the stacker, which bear the supporting rollers articulated with the drives of rotation and with the drives of turning in vertical plane. The sheet stacker is equipped with additional supporting rollers articulated with the drives of their displacement in the direction perpendicular to the axis of the stacker, horizontally located guides installed in the carriages, and by vertically located chutes articulated with the carriages. Each of the drives of displacement of additional supporting rollers is made in the form of, for example, hingedly located on the carriage cylinder, which stock is hingedly articulated with a rod installed in horizontally located guides, at free end of which a supporting additional roller is fastened with possibility of rotation. Additional supporting rollers and gravity slides are located in the spaces between said supporting rollers under them. |
