Abstract: This is a rotary sheet material cutter and creaser, particularly intended for cutting and creasing cartons out of rolls of sheet cardboard. It includes a rotary cutting and creasing die geared together with a rotary anvil and particularly provided as an attachment for or end part of a carton-printing printing press, which printing press is conventional, and which may be multi-color. The cutter and creaser of this device is synchronized with the printing press by having its gearing geared to the printing press gearing in a conventional manner, and may be provided in gangs for operation on a wide roll of material, thus providing a multiplicity of cut-out cartons simultaneously. The sheet material is fed through the conventional printing press in a conventional manner from a roll, then through this device to cut out and crease the folds of the carton blank. As thus completed, the blanks are deposited in a collecting station, and the waste from which the blanks are cut is then collected in a waste roll for disposal.
