A cutoff machine for non-metallic tubes comprising a pair of rotary saws in transverse alignment within a plane perpendicular to the axis of feed of tube stock incident to continuous discharge from a tube-forming machine, a pair of motors simultaneously driving said saws in opposite rotary directions respectively toward said tube stock from opposite sides, powered propelling mechanism which is fluid actuated and activated by an electric signal instigated by the forward end of the moving tube striking a target switch which originates all subsequent sequential functions of the machine by moving the saws longitudinally from and toward a starting position in opposite directions parallel to the movement of the tube feed stock, additional power mechanism operable to move said saws simultaneously toward said tube stock while said saws are advancing evenly with said stock, first control mechanism operable to effect withdrawal of said saws from said tube stock and a severed tube section prior to terminating longitudinal movement of said saws in the feeding direction of said tube stock, second control mechanism operable to cause reverse longitudinal movement of said saws simultaneously toward said starting position, and discharge mechanism operable to receive cut tube sections immediately upon severance from the stock and clear it from the path of successive cut tube sections.
