If the straightener is made to correct a clockwise curvature, it is often impossible to correct a counterclockwise curvature. The only available adjustment is the variation of the degree of bend at each station. This is true even for straighteners that have banked upper rolls that pivot for two-point adjustment.

installation Operating Instructions For Straighteners / Rapid Roll Align the Rapid Roll with the feed allowing sufficient space for free stock for the feed. The loop control arm roller rests on the stock between the Rapid Roll and the press. The Rapid Roll should be bolted to the floor, especially when used to pull stock from a non-powered reel. The pinch rolls must be parallel in the lateral (horizontal plane to insure that there will be equal pinch force along the full width of the stock).
Start up procedure Prior to applying power to the straightener, all the controls on the machine should be reviewed. A brief summary is listed below. Main Console And Controller The main control console with controls is mounted on the cabinet of the straightener. Located on the face of the console are five switches, one potentiometer, one push-button and one or two circuit breaker reset switches, which are explained below. 4.

dancer arm loop Dancer Arm Loop Height Adjustment Three different loop sensing arm operating positions are selected manually during set-up. By selecting the higher number, the zero point of the dancer arm is raised from its rest position to the angle shown (as indicated 0-2). The dancer arm will move from rest position to the angle selected before the straightener rolls begin to rotate.
standard straightener components Curve Up/Down Adjustment Entrance Guide Roll Block Some applications have dies that cannot accept anything but flat stock and other dies run better with the material curving up or down to miss the built in edge required in the die. Before this feature was added, operators would under straighten or over straighten the material to suit their needs but in doing so would severely change the material entering the die.
operation Once the straightener has been tested and all the functions work, then it should be tested for what it was designed to do and that is to remove coil set. Retract all of the idler rolls and the exit pinch roll to a position so when the cover is closed the material is not being deformed. Open the cover of the straightener and position the edge guides for maximum width.
troubleshooting guide MAIN SWITCH ON BUT NOT LIT 1. CB tripped. a. Reset CB. 2. Unit not plugged into main power. a. Plug into main power source. 3. No power in incoming line. a. Check outlet. b. Check power cord. 4. Loose wiring. a. Check terminals and connections. MOTOR CREEPS IN STOP POSITION 1. R1 & R3 pot on 69100034 board not correctly adjusted. a. Readjust pots so rollers stop. Call factory. UNIT TURNS BUT WON’T JOG 1. Selector switch not in jog position. a. Select jog. 2.
69100034 TAUT STOCK OUTPUT The 69100034—Proportional control board has a taut stock output. The output must be wired to a solid state relay as the max current draw is 20 MA. The solid state relay’s contact can then be incorporated into the electrical control circuitry. The output can be wired so that the relay is either on or off with the dancer arm down. When the dancer arm reaches the set point for taut stock, the relay switches state.
safety warning – please read carefully RAMM Solid State DC Motor Speed Control This product should be installed and serviced by a qualified technician, electrician or electrical maintenance personnel familiar with its operation and the hazards involved.

straightener sa3 - sb4 OPERATION For set up only, place a short length of stock about four feet on the bottom rolls, between the pinch rolls. Set the entrance guide rolls before lowering the cover. Make sure the top rolls are retracted to prevent stock deformation. Apply light pinch roll force on the stock to insure adequate assisting pulling force on the stock and to prevent slippage of the stock over the straightener rolls. Never overload the pinch rolls.
