Fife uncoiler systems allow the strip to be continuously payed off to a predetermined point, utilizing either edge guide or center guide sensors. The wide-gap reflex edge sensor (A) shown here is designed to be located adjacent to the uncoiler, providing stable, accurate edge guiding results. An alternate solution to uncoil guiding might be the installation of a narrow-gap, wide-band, center guide sensor (B) downstream of the pinch roll/flattener and a control algorithm which compensates for the phase lag in such a system.
	Features designed into Fife heavy-duty electrohydraulic power units resulted from an extensive "needs" study conducted among steel mill engineers responsible for specifying and maintaining strip guiding equipment. As a result, these power units are rugged, reliable, and responsive, providing simplicity of design, operation, and maintenance. They employ modular motor-pump assemblies for ease and speed of maintenance, pump replacement, etc. With optional standby power, they can operate with one motor -pump module running while the other is being serviced. Internal check valves automatically isolate the active and inactive modules.
	1. Vertically mounted pumping module eliminates pump-coupling-motor alignment problems.     Complete power module is easily removed with portable hoist. An optional standby module     functions independently to assure continuous operation during parts replacement or routine     maintenance. 2. Submerged hydraulic pump increases life, reduces noise level, and eliminates internal     damage from cavitation encountered with exposed pumps. 3. Pressure-compensated, variable volume, piston-type hydraulic pump runs "unloaded"     except on demand, greatly reducing power consumption, and providing maximum pump life. 4. Proportional electronically actuated, two-stage, spool-type servo valve provides optimum     accuracy, reliability, and efficiency, Can be furnished with multiple servo valves for alternate     control of multiple coilers. 5. Submerged piping and subplate porting eliminate most external piping 6. Compatible with phosphate ester fluid and other fire-resistant fluids 7. Auxiliary hydraulic ports for optional double-stub traversing or sensor positioning circuits

	This package is an integrated hydraulic circuit consisting of subplate-mounted, electrically operated valves. The solenoids are prewired to a terminal box, and the hydraulic connection can be made easily at the side of the manifold block. This system is used where it is desirable to operate two stubs or cone mandrels simultaneously or independently. It may be used with or without a guiding circuit. In seeking dynamic equilibrium, a strip will tend to track perpendicularly to an oncoming roll and is subject to factors of rigidity, stress distribution, inertia, friction, and load distribution. These and other factors cause uneven stress and "offtracking" that create expensive problems. The solution is the proper selection and application of Fife intermediate guiding systems. Control systems are available for both edge guiding and center guiding requirements. Most intermediate guides are furnished with a center guide sensor-making adjustments for strip width changes unnecessary and eliminating the need for operator attention.
