7. Adjustable Moistening
To give the most efficient moistening for all kinds of tapes, your machine is
equipped with an adjustable water level and adjustable weights on the
thermostatically controlled heater and pressure plate assembly.
Increasing the height of the water level increases the amount of water
applied to the tape.
Increasing the weight on the top heater and pressure plate assembly
spreads the water evenly on the tape. The weights (3 in number) are
attached to the front end of the top heater and pressure plate assembly
and held in place by 2 screws. To remove, loosen the screws slightly and
lift out the weights as required. Lightest pressure is with all weights
removed. Maximum pressure is with all weights in place.
For example, certain paper tapes have adhesives which normally require
somewhat less water for best moistening results. With such tapes very
little weight is required and all weights at front of pressure plate and top
heater assembly are generally removed. Other tapes requiring slightly
more water usually work best with medium weight pressure. Only one or
two weights should be at the front of the top heater and pressure plate
assembly.
Other tapes may have as much as two or three times the amount of
adhesive to be moistened.
8. Top Heater Settings
Finding the correct setting for the tape you are using is a matter of simple
testing. Turn the adjustment knob (clockwise) to the highest setting, then
back off slightly to the lowest temperature setting that best meets your
needs.
