feature is made possible by Graham Engineering’s
proprietary spiral flow diverter head. Available on all of
the company’s accumulator head machines, the diverter
head also provides continuous internal cleaning during
production, eliminating the need to disassemble the
head for cleaning and increasing production availability.
Modular clamp station for Revolution MVP®
rotary wheel blow molder. A key innovation in
the Revolution MVP system is that each clamp
station is independent of the others, with all forces
self-contained within the clamp. Water manifolds
through the platens to facilitate quick mold change,
and individual clamps can be removed for offline
maintenance to reduce downtime.
This modularity enables the user to vary the number
of clamp stations from 12 to 24 on the same
platform and configure the wheel based on the
application and bottle height.
Welex Evolution® sheet extrusion system, a
complete production line for use in sheeting,
winding, and in-line thermoforming applications
and equipped with XSL Navigator control. While
the equipment on display at NPE will be for thin-
gauge polypropylene, the Evolution system can be
customized for widths from 36 to 90 in. (90 to 230
cm), gauges from 0.008 to 0.125 in. (0.2 to 3.2 mm),
and throughputs up to 10,000 lb./hr. (4,535 kg/hr.).
Monolayer or co-extrusion systems are available,
with up to nine extruders. In addition to a
customized roll stand, the Evolution system can
also be equipped with screen changers, melt pumps,
mixers, feedblocks, and dies. Additional features
of the line on display include a proprietary roll-
skewing mechanism for thin-gauge applications
while maintaining quick roll change and electric
gap adjustment under full hydraulic load without
interrupting production.
