A tape slitter has a pair of parallel arbors carrying sets of cutting knives through which webbed material may be drawn and severed into elongated strands. A slide cartridge is coupled at its opposite ends to one of the arbors and a force transmitting device, all of which are arranged to be simultaneously and selectively slid in opposite axial directions. Axial force is applied to the force transmitting device by a detachable torque wrench which urges the sets of knives into positive cutting engagement. Movemment in the reverse direction drives opposite sides of the knives into cutting engagement. During shifting of the knives from one mutual cutting position to the other, the web material remains continuously threaded.
