A machine for forming local projections and depressions (creases) on the surfaces of sheet stock, as well as for rolling wire, straightening creases, and cutting in sheet material up to 3 mm thick. Stock is shaped by rolling between two correspondingly shaped rollers rotating in different directions and mounted on the ends of the machine shafts. Depending on the thickness of the material and the operation being performed, the distance between the axes oHhe rollers can be changed by raising or lowering one of the shafts by means of a screw with a handle. To form a crease at a specific distance from the edge of the stock without marking, a removable and adjustable rest is mounted on the creasing machine. Creasing machines may be operated by hand or by a mechanical drive.
