A system for delivering a coolant fluid to a workpiece has a reservoir for retaining the fluid, a pump for delivering fluid from the reservoir, a supply line in communication with the workpiece and a diverter valve. A bypass line is in communication with the diverter valve, and the valve may be utilized to deliver fluid from the reservoir to the workpiece or to bypass the workpiece and circulate fluid back to the reservoir. The system also includes a fluid return line for conveying fluid from the workpiece back to the reservoir.

The invention claimed is: 1. A system for the continuous production of shaped, metallic members, said system comprising: a payout station operable to support a coiled web of metal, and to feed out said web to the other stations of the system; a roll forming station, including a plurality of roll forming dies therein, said roll forming station being operable to receive said web, continuously, and form said web into a continuous, elongated body having a preselected cross-sectional profile; a cutting station operable to cut said continuous, elongated body into a plurality of members, each member having said preselected cross-sectional profile; a heating station operable to heat said members to a temperature sufficient to effect a change in a physical property of the metal comprising said members; a feeder associated with said heating station, said feeder being operable to receive cut members and to transfer said cut members into said healing station; a processing station operable to receive a heated member from the heating station; and a coolant fluid supply station in which a coolant fluid is delivered to said processing station from a reservoir by a supply line and circulated back to said reservoir from said processing station by a return line, said coolant fluid supply station including: a first pump for delivering said coolant fluid to said processing station, a bypass line which is in fluid communication with said first pump and with said reservoir for establishing a fluid flow therebetween, and a selector valve associated with said bypass line for selectively establishing a fluid flow between said first pump and said processing station or said first pump and said reservoir. 2. The system of claim 1, wherein said coolant fluid supply station further includes a second pump which is in parallel with said first pump, said second pump being operable to deliver said coolant fluid to said processing station. 3. The system of claim 2, including a selector for selectively activating said first pump or said second pump. 4. The system of claim 1, wherein said coolant fluid delivery station includes a preheater for warming said fluid before it is delivered to said processing station. 5. The system of claim 1, having a heat exchanger associated with said return line for extracting heat from said fluid. 6. A system for the continuous production of shaped, metallic members, said system comprising: a payout station operable to support a coiled web of metal, and to feed out said web to the other stations of the system; a roll forming station, including a plurality of roll forming dies therein, said roll forming station being operable to receive said web, continuously, and form said web into a continuous, elongated body having a preselected cross-sectional profile; a cutting station operable to cut said continuous, elongated body into a plurality of members, each member having said preselected cross-sectional profile; a heating station operable to heat said members to a temperature sufficient to effect a change in a physical property of the metal comprising said members; a feeder associated with said heating station, said feeder being operable to receive cut members and to transfer said cut members into said heating station; a processing station operable to receive a heated member from the heating station; and a coolant fluid supply station in which a coolant fluid is delivered to said processing station from a reservoir by a supply line and circulated back to said reservoir from said processing station by a return line, said coolant fluid supply station including: a pump for delivering said coolant fluid to said processing station, and a bypass line which is in fluid communication with said pump and with said reservoir, said bypass line being selectably operable to divert at least a portion of said coolant fluid from said pump back to said reservoir so that said at least a portion of said coolant fluid does not flow to said processing station.
