Principle
of operation
Goodman
On-Demand/Flywheel Cutting Systems are positioned immediately
downstream of a hot melt adhesive water cooling trough or vacuum
sizing equipment. The cooled extrudate is fed into the cutter
by a caterpillar puller which is integral with the cutting system
(shown), or configured independently.
In on-demand
mode, the distance traveled by the extrudate is measured continually
by an electronic length counter/encoder which transmits a signal
to the system controller. When a preprogrammed cut length has
been traveled, the controller activates the on-demand indexer
drive/blade to make one revolution, slicing the hot melt rod
cleanly and accurately, up to 750 times per minute.
In flywheel
mode, the cut length is determined by the ratio between the extrudate
distance traveled and the (adjustable) flywheel RPM, providing
up to 2000 cuts per minute. |
