is above the start speed and deactivated if the line speed drops below the
stop speed. With continuous gluing, no pattern is programmed and no
trigger signal is required.

continuous bead patterns.

Autospot Beads
With this bead type the channel output operates in dot mode when the
pattern controller is below the activation speed and operates in normal
mode when above the activation speed. This bead type is used to relieve
residual pressure after a sudden machine stop.
NOTE: If the production machine speed is above the maximum dot speed
(Max Dot), the maximum dot speed is used (also refer to Page 51).
