applied to Pattern X and Pattern Y at the start
signal. Increases and decreases in pressure
of each Pattern Cycle in order to maintain the
correct pattern length and position even if the
product speed varies.
During each pattern cycle, a servo signal is
uto and manual operation may be selected
calculated based on product speed as sensed
by the speed tracker and the volume gain
selected by the operator. This signal is sent to
a servo controlled pump or servo controlled
fluid pressure regulator which raises and
lowers fluid pressure in direct proportion to the
increase and decrease the flow (volume) of
fluid. This results in a constant deposit of
adhesive even if machine speed varies.
A
for the servo signal. Auto functions as just
described. In manual, the servo signal is fixed
at a setting corresponding to the programmed
volume gain value, and will not vary as
machine speed varies.
