CHAPTER 6
CONTROL PANEL FUNCTIONS
PORTABLE AND FLOOR MOUNTED MODELS
1. Forward and Reversing Valve: Controls direction of rotation of Impregnator rolls.
2. On-Off Valve-Resin Pour: Controls resin flow from pump. Up position, to run pump; down
position, to stop pump.
3. Speed Control Regulator: Governs speed at which material will travel through machine.
4. Pressure Regulator: Solvent Pressure Pot.
5. Pressure Gauge: Solvent Pressure Pot.
CAUTION: Do not operate flush tank pressure above 60 PSI.
6. Feed Roll
– Open: Opens feed rolls to remove wrinkle from between feed and resin rolls.
7. Re-Set Control: When rolls are shut off by the bump bars, (panic stop bars) this button must be
pushed to re-activate pneumatic circuit to the roll drive.
CAUTION: If forward and reversing valve is left on after panic bars have stopped machine,
machine will start when re-set control button is pushed.
8. Solvent Flush Control: When button is pushed, solvent is flushed through gun head.
BRIDGE CRANE AND GANTRY MODEL CONTROL PANEL
1. Direction Control Stick: Pushing control stick in the direction you wish to travel will activate one
or more motors which will result in a modulated speed in the direction desired. The farther the
stick is pushed from the center position, the faster machine travels; up to twenty feet per minute.
Let go of stick and motion will stop and stick will return to center position.
2. Roll-Turret Control Stick: This, too, is a modulated speed control. Push stick forward and rolls
will turn to feed reinforcement through. Pull back and operation will reverse. Let go of stick and
motion will stop and stick will return to center position. Push the stick left or right and
Impregnator will rotate in the desired direction, up to 360º rotation. Let go of the control stick,
motion will stop and stick will return to center position.
NOTE: Do not reverse the impregnating rolls with a wet laminate in rolls. Damage to rubber
feed rolls could result if exposed to resins or solvents.
3. Resin Pour Control: Holding button on the top of the roll-turret control stick down will activate
the automatic gun circuit and catalyzed resin will flow to the resin roll bath.
4. Feed Rolls-Open Button: Holding button down on top of Direction Control Stick, will open the
rubber feed rolls. This feature is used to remove wrinkles that may form between feed rolls and
resin roll. By opening the feed rolls; the weight of the laminate and driving force of the resin
rolls will pull the material tight.
5. Panic Stop Bars: The function of the control is to give a measure of safety to the operator when
working around the Impregnator rolls with roll guards up. Any slight pressure on either bar (3
pounds or less) will instantly stop the rolls from turning.
