ABSTRACT:
A flying cutoff apparatus for cutting longitudinally moving and axially rotating tubing includes a track positioned along and generally parallel to the direction of longitudinal movement of the tubing, a carriage mounted on the track adjacent to the tubing for movement along the track, a cutter mechanism mounted on the carriage adjacent the tubing and stationary relative to axial rotation thereof, and an actuator, such as a hydraulic cylinder, mounted on the carriage for moving the cutter mechanism relative to the carriage and between non-cutting and cutting positions. The cutter mechanism also is mounted on the carriage for movement with the carriage and relative thereto in transverse relation to the direction of longitudinal movement of the tubing between a non-cutting position wherein the cutter mechanism is disengaged from the tubing and a cutting position wherein the cutter mechanism clamps and thereby moves with the tubing as the same moves longitudinally and operates concurrently to cut the tubing as the same rotates relative to the cutter mechanism. The cutter mechanism includes a cutting roll disposed on one side of the moving tubing and a pair of backing rolls disposed on an opposite side thereof which clamp the tubing therebetween when the cutter mechanism is in its cutting position. The movement of the carriage and cutter mechanism with the moving tubing is due solely to the cutter mechanism clamping the tubing when in its cutting position.
