ELECTRIC ADJUSTMENTS
ROLL GUIDE ADJUSTMENT
• The tape roll guides in the tape basket should be
properly set for the widths of tape being dispensed.
The roll of tape should preferably be centered
between the frames by confining the tape loosely
between the roll guides, which engage in between
the spring-loaded spacers on the tie rods.
• To set the roll guides in position, lift them out, move
to the desired position and re-insert.
WATER LEVEL ADJUSTMENT
• The amount of water required for proper moistening
of different grades and types of tape will differ.
Heavier glues on reinforced tapes will normally
require a high water level. Lighter tapes require less
water and a lower level. The water level is controlled
by the position of the front water bottle bracket. To
adjust the water level, loosen the two screws on the
bottle bracket, move to the desired position and
tighten both screws.
ADJUSTABLE MOISTENING AND TOP HEATER
SETTINGS
• 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 thermo-
statically controlled top 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 increases the amount of water
applied to tape. The weights (three in number) are
attached to the front end of the top heater and
pressure plate assembly and held in place by two
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 gummed paper tapes have
glue, which normally requires 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. The heater setting should be at the
11 o'clock position.
• Other tapes requiring slightly more water usually
work best with the medium weight pressure. Only
one or two weights should be used at the front of the
top heater and pressure plate assembly. Here again
the heater setting generally is at the 12 o'clock
position.
• Other tapes may have as much as two or three
times the amount of glue to be moistened. With
these tapes, all the weights are usually required with
the heater setting at the 1 o'clock position.
A SIMPLE MOISTENING TEST
• Too much water results in a weak seal. Furthermore,
the tape, when applied to the carton, will tend to
slide and require excessive rubbing. If this happens,
one or more weight bars should be removed from
the top heater. If necessary, lower the water level
by adjusting the front water bottle bracket. Because
excessive pressure results in unusual brush wear, it is
always best to reduce pressure before lowering the
water level.
• Use a pattern and deposit test to check for too little
water.
