ABSTRACT:
A combination is provided including a conveyor for bringing a zigzag folded web of forms to a fold-cutting device. The device comprises a table movable in the vertical plane, vertical confining walls for the form stack, a unit-opening finger supported such that it can be brought partly into the form stack to lift the upper forms so that a slit is formed. A flexible plate extends and moves in the horizontal plane so that it can be brought into the formed slit. A knife plate positioned below the flexible plate is movable together with the flexible plate. A cutting edge of the knife plate is positioned at some distance behind the leading edge of the flexible plate until the flexible plate is moved adjacent the fold to be cut and there is brought to a stop, after which the knife plate can be moved an additional distance for cutting of the fold.
