  • Stack forming and removing apparatus with undersheet placement
    Patent number: 6241233
    Abstract: An apparatus for stacking flat printed products, wherein a stack (22) is ejected from a stacking well (12) by means of an ejector (30), and a cover sheet (28) is pulled into the stacking well (12) as the ejector ejects the previously formed stack. The next stack (22) then comes to lie on this cover sheet (28). Arranged on the ejector (30) is a support (38) having a driving pin (40) which points downward. In each case, a cover sheet (28) is pinned on to said driving pin (40) by means of a support plate (50) which can be lifted and on which the cover sheet is positioned. By changing the position of a stripping lever (46) after the stack (22) has been ejected, the cover sheet (28), which has been pulled into the stacking well (12), is stripped off the driving pin (40).
