8b. Measure the distance from the back edge of the tab
to the point at which the glue stops.
8c. Both dimensions should be 1.0”. If not, adjust the
ratio compensation as described in the “Adjusting
the Ratio Compensation” section.
9. Run another sample product through the glue station.
10. Stop the parent machine before the product is folded and
examine the glue pattern.
The parent machine must run above
the minimum speed setting in order for
the glue valve to operate. If the
minimum-speed LED on the main board
is off, the parent machine is running
below the minimum speed. If this is the
case, turn the “MIN SPEED” pot on the
main board CCW so that the LED
illuminates at jog/setup speed.
11. Compare the applied glue pattern to the values seen on the
front panel of the control.
12. If the pattern does not start at the proper flap setting, check the
cell-to-gun setting on the main board. An increase of the cell-to-
gun value will move the glue pattern further back on the product.
A decrease of the cell-to-gun value will move the pattern forward
(pattern begins sooner).
Do not adjust this dimension any more
than + 0.50 inches of the measured
dimension.
13. Run at full speed and measure the glue pattern length and the
start dimension.
If pattern starts too late, adjust DS1 to
increase time (see Tables 7-3 and 7-4).
If pattern is too long, increase DS2 time
according to time chart.
If P1 and P2 (ON DLY and OFF DLY)
are used to adjust time, CW (clockwise)
decreases time and CCW
(counterclockwise) increases time.
14. Use the glue-pressure adjust knob on the front panel of the
control to fine-tune the amount of adhesive applied to the
product.
