Pressure & Height Display
: A display located on the Control Panel above the Heat Button. The height of the Nip,
or space between the top and bottom rollers, is indicated from 0 to 25 millimeters on the display. Directly above the
height indicator are a series of LED lights, labeled in increments of 20 from 0 to 100, that indicate the percentage of
pressure applied to material in the Nip. The 0 LED remains illuminated at all times. When the top roller is lowered to
rest on the bottom roller (commonly referred to as the “Sweet Spot”), the 20 LED will light to indicate 20% pressure
has been exerted. Slowly rotate the Height Wheel clockwise to apply more pressure. As pressure is applied, the LED
lights will successively illuminate to show the percentage of pressure applied. For best results, set the pressure to 20%
or 40%. Drytac’s unique lift mechanism design allows for evenly controlled pressure over the entire contact area. To
prevent excessive pressure, premature failure of the machine, or damage to materials during processing, maximum
spring compression is restricted. To properly adjust pressure, refer to
Setting Roller Pressure
on page 11.
Speed Control Knob
: A knob located on the Control Panel to the right of the Roller Button and F/R Button. Used to
control the speed of the motor-driven bottom roller. Rotate the knob to the right to increase the speed of the roller,
and rotate the knob to the left to decrease the speed. Speed control will not affect reverse speed or the speed of the
roller when the photocells are interrupted during Foot Pedal operation. The roller will move at a slow, steady speed (jog
mode) until the Foot Pedal is released. When the photocell obstruction is clear, the set speed will resume by pressing
the Roller Button.
Supply Shaft
: A shaft used to support and feed a roll of material. Rubber cords lock the inside of the core and keep the
roll in place.
Take-up Shaft
:
A shaft used to remove and wind up the release liner from the roll of material being used. Rubber cords
lock the inside of the core and keep the roll in place.
When any shaft is installed, the slot end must be properly oriented to
fi
t in the drive mechanism located on the right
end case. Consider this before lifting the loaded shaft into position. Once in position, insert keeper pins in the cups to
secure the shaft and prevent it from lifting from the cups. All shafts will
fi
t into any position on the machine.
Height Wheel
:
A wheel located on the front of the right end case. Turn the wheel clockwise to raise the top roller and
counter-clockwise to lower it.
Foot Pedal
: A foot switch positioned on the
fl
oor within easy reach of the operator. Used to activate the bottom roller
or bypass the photocells when webbing the machine. Be particularly cautious when operating the equipment with the
Foot Pedal as the rollers WILL NOT STOP when the photocells are interrupted. An audible alarm will sound, but the
rollers will continue to turn at a reduced speed.
Photocells
: Electric eyes located on the left and right sides of the machine in front of the rollers. A safety feature used
to protect the operator from the Nip area between the rollers. When an object interrupts the photocells, the rollers will
stop turning and an alarm will sound. Once the object is removed from the Nip area and the Roller Button is depressed,
the rollers will start turning again at the speed set on the Speed Control Knob. When an object interrupts the photocells
