8. The Pressure and Height Displays are directly above the HEAT display. The Nip opening
(or gap between the upper and lower rollers) is indicated on the LED Display in millimeters
from 0 to 50 mm or two inches. Directly above the Nip Opening Display, a series of LEDs
(labeled from 0-100) light up to show the percentage of pressure being applied to the
material in the nip. The (0) light stays lighted constantly. When the Top Roller is lowered to
rest on the Bottom Roller (what is called the “Sweet Spot”) the (20) light will light up
indicating twenty percent pressure is being exerted on the material in the nip. With a very
slight rotation of the Hand Wheel clockwise, increasing pressure is applied and the LED’s
will successively light up to show the percentage of pressure applied. This feature is for
repeatability in processing. The suggested pressure setting is 20 or 40 % for the best
results with the majority of applications. The unique Drytac lift mechanism design achieves
evenly controlled pressure over the entire contact area. To prevent excessive pressure and
premature failure of the equipment or damage to materials processed and/or the
mechanism, maximum spring compression is restricted.
The Hand Wheel is located on the front of the right end case. Simply turn the hand wheel to
raise or lower the top roller.
The Supply Shaft holds the adhesive or laminate material, while the Take Up or wind-up
Shaft holds the release liner. The two shafts below the table level can be used as either
supply or take up as the application calls for.
When any of the shafts is installed, the slot end must be oriented properly to
fit in the drive mechanism located on the right end of the machine, as you face it from the
front. The operator and the assistant should consider this prior to lifting the loaded shaft into
position. Once in position, keeper pins can be inserted in the cups to secure the shaft from
lifting from the cup.
Setting Roller Pressure
The nip gap is the space between the upper and lower main rollers. Both the nip gap and the
processing pressure are controlled by the Height Adjust Hand Wheel, located on the front of the
right cabinet, which raises or lowers the upper roller. The roller height should be adjusted
according to the images or substrates being processed. Normal operating range is between 20-
40% for most applications. Excessive pressure can create wrinkles and damage substrates.
Over laminating and Encapsulation: To process thin images the nip gap should be closed with
the pressure set to 40%.
