The disclosure is directed to a new scrap kick-out conveyor for a continuous buttweld pipe mill installation. The pipe mill includes a scrap cut-off saw, located between the welding mill and the subsequent processing mills, and the kick-out conveyor is located downstream of the scrap saw. The conveyor includes stock advancing rolls, for supporting and advancing the pipe stock, and inboard and outboard guide rails for laterally confining the pipe. Means are provided for retracting selected portions of the outboard guide rail and for diverting selected portions of the inboard rail to lie across the pass line, such that the oncoming scrap section is diverted off of the conveyor. An inclined discharge apron is provided adjacent the outboard guide rail, leading to a scrap bin. The retractable portion of the outboard guide rail is arranged to retract downwardly, and is provided with an inclined upper surface to facilitate gravity discharge of the scrap sections.

The disclosure is directed to a rotary saw for cutting sections of scrap pipe in a pipe forming mill. The saw includes a frame, mounted for rotation above the pass line and carrying cutting saws at each of two ends, enabling two cuts to be made for each revolution of the rotary frame. The individual saw mechanisms are mounted for rotation in the frame and are tied to the stationary frame of the apparatus in a manner to maintain the saw blades at all times in a vertical plane for cutting a horizontally moving pipe. Both of the saws are driven by a common, motor driven shaft, which is concentric with the rotary mounting shaft for the saw frame and is gear-connected to the respective saw blades. A pipe lifting cam is synchronously associated with the rotation of the saw frame, for lifting, supporting and confining the moving pipe each time a saw blade moves into cutting position. The entire scrap saw unit is movably mounted in relation to the pipe pass line, enabling the saw to be retracted well away from the pass line during normal operation of the mill.
