<p>A cutter and creaser is fabricated from the components of a flat bed letter press. A carriage is mounted on the press frame member for horizontal longitudinal reciprocal movement between the feed end of the press and the delivery end of the press. A die plate suitable for cutting or creasing paperboard or the like is positioned on the upper surface of the carriage, or in some cases, wrapped around the cylinder. A cylinder is positioned above the carriage and is arranged to press a sheet into the die plate as the carriage moves reciprocally thereunder. A sheet delivery device includes an inclined feedboard that feeds the front edge of the sheet to the front edge of the carriage where the front edge of the sheet is engaged by gripper means. The carriage is advanced forwardly beneath the cylinder while the sheet is engaged by the gripper device on the carriage to press the sheet against the die plate. A sheet delivery device includes gripper means to engage the front edge of the sheet on the carriage and transfer the sheet from the carriage to a stacking device. Another embodiment includes gripper means on the cylinder to engage the front edge of the sheet and transfer the sheet to the gripper device on the front of the carriage.</p> |
