A rotary tab cutter for cutting tabs such as glue taps in a box board blank. The device has a pair of opposing shearing cutters mounted on timed rotating shafts which cooperate to cut the tabs in the nip of the rotating cutters. When a pair of blades are mounted on each of the opposing cutters at an angle to the axis of rotation, the opposing cutters cut a tapered leading edge and a trailing edge on the tab. The shafts may be driven through a drive train by a servo motor, and including a control device to cut tabs of differing length. A sensor for detecting a leading edge of the sheet is sending signals to the control device.
