Trailing Edge Detection

DELAY equals the distance from the Glue Valve to the start of the LINE (glue).
DIRECTION OF TRAVEL

Line

The LINE parameter is the "glue" portion of each EVENT.
1. Depress the desired CHANNEL button until the LED to the left of LINE is illuminated.
2. Depress the DIGIT button until the desired programming granularity is selected.
3. Rotate the VALUE knob until the desired LINE value is selected. The LINE value
should be set as the desired length of a continuous glue line or a series of "dots" or
"stitches".
4. Displayed values range from 00.00 to 99.95 inches in 0.05 inch increments.
NOTE: The cumulative distance for all four EVENTs (DELAY and LINE) in a single
Program may not exceed the maximum distance of 99.95 inches.

Gap

GAP is used when a series of "dots" or "stitches" is desired instead of continuous glue for
the LINE portion of an EVENT. The Glue Applicator is energized for the duration of
SPIKE TIME if no value is entered into STITCH (see the next section for an explanation
of STITCH). The DPC-2 Control Unit divides LINE by GAP to determine the number of
"dots" that will be applied to the product.
1. Depress the desired CHANNEL button until the LED to the left of GAP is illuminated.
2. Depress the DIGIT button until the desired programming granularity is selected.
3. Rotate the VALUE knob until the desired GAP value is selected.
4. Displayed values range from 00.00 to 05.00 inches in 0.05 inch increments.
The diagrams below illustrate a single LINE duration with GAP = 00.00 and with GAP =
"Z" (some value greater than zero) and a SPIKE TIME = "X".
