The method of making a rotary cutting cylinder comprises forming a cylindrical section having longitudinally spaced grooves, with at least a porticr cf each longitudinally spaced groove being tangential to the cylindrical section. A longitudinal slot is formed in the cylindrical section crossing th grooves. The slot has opposing sidewalls. A cutting rule is placed in the slot. A mounting bar is inserted in the slot having longitudinally spaced set screws and aligning set screws with the grooves in the cylindrical section. The set screws are tightened to urge the cutting rule against one sidewall of the slot and urges the mounting bar away from the cutting mole and against the opposite sidewall of the slot to secure the cutting rule and the mounting bar in the slot.
