NOTE: A GAP value greater than zero automatically changes a LINE to a series of
"dots" unless STITCH is also programmed.

Stitch

STITCH is used when a series of intermittent glue patterns longer in length than a "dot"
is desired instead of a continuous LINE. The DPC-2 Control Unit divides LINE by the
sum of GAP plus STITCH to determine the number of intervals. The Glue Applicator is
energized at 48VDC for the duration of SPIKE TIME, the voltage is then reduced to
16VDC for the remainder of the STITCH length. LINE, GAP, STITCH and SPIKE TIME
must all be properly programmed to attain the desired end result. Review the sections on
LINE and GAP above for details concerning these parameters. SPIKE TIME is presented
in the next section.
