Rotary Fly Knife cutters:
We manufacture fly knife cutters for extrusion profiles up to 150mm+. A blade
rotates at right angles through the product at a programmed interval to produce
the desired length. Our fly knife cutters can cut any extruded product that can
be cut by a knife, i.e. plastics, rubber, food. Send us a sample so that we may
determine the best way to cut your product. Allow us to recommend the best style
of cutter to suit your particular application.
We supply a choice of cutter
styles using clutch brakes or servomotors. Servomotors are the most accurate and
use less mechanical parts but their trade off is this is expensive technology.
In many cases the older technology provided by clutch brake units is more than
sufficient. We have many of these older units still running 24 hours a day, 7
days a week (many over 15-years old)!
Our cutters use a purpose built
controller supplied by Lyons
Electronics. Other manufacturers use complicated HMI panels or a variety of
complex switches. Our control is very easy to use and is probably the most
accurate device of its type on the market.
Various methods of length
control are available:
Timer Mode: Uses a time interval with resolution down
to one millisecond. This is good with stable line speeds and does not require a
length measuring encoder.
Encoder Mode: For tighter tolerance an encoder is
mounted on the Haul-off belt or product. The 650 controller provides scaling
which simplifies length set up. 250,000 max counts per second - equivalent to
125 kHz.
Product Mode: A switch, sensor or electronic eye can be used to
send a pulse to the controller, which will then give the cut. A Hold Off timer
is included to gate off the input for products that bounce back in front of the
sensor when cut (to avoid double cutting).
Flywheel Mode: The cutting arm
spins at a fixed RPM.
We also manufacture combination machines that have the
Fly Knife Cutter & Haul-Off together on a single frame.
Coilers:
We manufacture a wide range of coiling machines to handle
the smallest medical tubing up to 100mm diameter rigid pipes.
Available as
single head or multiple head or double sided to handle dual extrusions, with
dancing arms, layering devices & collapsible
bobbins.
Haul-Offs:
We manufacture Caterpillar Haul-Offs
up to 2 metres long with 1700mm gripping length using multiple ribbed poly V
belts with various coverings upto 500mm wide.
With AC or servo geared motors
mounted directly on the booms.
We can also supply a specialist control system
to produce bubble tubing by momentarily stopping the haul-off & blowing air
into the extruder head.
Conveyors / Tipping Tables:
We
manufacture Conveyors with a push bar or air blow system to handle flexible
extrusions when cutting up to 6 metre lengths, this machine will collect product
in a tray for easy packaging. Available with a second tray to batch product if
needed.
We also manufacture Tipping Tables for rigid extrusions.
