two Auxiliary Sockets (PHOTO 9) and turn on the
heater power switch.
Allow several minutes for the operating system to
start and for the hot knife to reach the operating
temperature. (PHOTO 10)
The hot knife temperature is set by pressing the up
or down arrows on the heat controller. Ensure the
fan is running before connecting an exhaust hose
to the fan housing.
The Main Screen should be visible when the system
is ready. (PHOTO 11)
• Set the feed roller pressure by pulling the ball-
chain over the slotted catch on the arm. Maintain
enough feed roller pressure to prevent the material
from slipping. Changing the roller tension before
setting the length since overall cut lengths can
change with different roller pressures.
• Press and hold the blue JOG button. The webbing
should feed through the rollers and into the
Cutting Module. When the end of the webbing
has exited the Cutting Module, press and hold the
yellow CUT button to cut. When the material cuts

PROGRAMMING
Toggle between US units (inches) and Metric units
(millimeters) by touching the Toggle Switch. You
may freely toggle between these two systems
without losing any entered data.
To set the required length, press the black LENGTH
display. Enter the length in the popup numerical
keypad. For inches, enter lengths to the nearest
hundredths of an inch (2 decimals). (Since the
system operates in millimeters, it will automatically
round all INCH length settings to the nearest
millimeter). For metric, enter the lengths to the
nearest millimeter. Press enter (ENT) when nished.
To set the required quantity, press the black QTY
display box. Enter the required number of cut
pieces into the pop-up numerical keypad. Press
enter enter (ENT) when nished.
Run a few test pieces to ensure that the program
settings are correct. To do this, press the green RUN
button. The machine should now measure and cut
automatically. Press the red STOP button at any
time to immediately stop the program. (Pressing
the green PAUSE button will stop the measuring
cycle without losing the length setting).
Check that the measured lengths correct. If not,
add or subtract a small amount to the length
setting. For problems with length setting or length
variation, see Troubleshooting.
A clean cut is achieved by the correct balance of air
pressure, cutting dwell time, and knife temperature.
For cutting dwell time adjustments, see the section
on TOUCHSCREENS. For problems in cutting, see
Troubleshooting.
Once the length is set correctly and the cutting
adjustments are acceptable, the machine is ready to
run automatically. Press the RESET COUNT button
to set the count to zero. Press the STOP button to
clear the last length.
OVERALL
Refer to the images shown for the location of the machine
components described below. Due to the many models
available, not all machines will look identical.
TOUCHSCREEN
There are several user screens available for operation,
settings and saving programs. The HOME or MAIN screen will
appear upon startup and from where most user settings are
made. The touchscreen may be activated by nger or stylus.
INDEXER
The Indexer (PHOTO 12) is the main part of the machine
that contains the controls and measures the webbing.
It consists of the red & black chassis, internal control
circuits (controller, drivers and power supplies), length
motor, feed rollers, and end sensor, air regulator and air
valves, emergency stop button, and external connections
and communications ports (USB and/or Ethernet). Indexer
Modules are congured during manufacturing to operate
from either left-to-right or right-to-left. Do not attempt to
change the feed direction of the indexer. The Index also
houses the interchangeable Cutting Module.

CUTTING MODULE
The interchangeable Cutting Module (PHOTO 13) is the
aluminum-framed unit that contains the knife assembly, each
with its own model sufx. There are several common types,
such as:
• SCL 5”/130mm hot knife
• GSL 6”/150mm guillotine
• USL 5”/125mm ultrasonic,
• AS3 3”/76mm alternating angle hot knife
• S3L 5”/125mm xed angle hot knife
• ASL 5”/130mm alternating angle hot knife
• G33 2.5”/60mm xed angle guillotine
• GAL 6”/150mm alternating angle guillotine
(many other types are also available)
The Cutting Module typically consists of the knife, air
cylinder(s), knife position sensors, as well as optional
components such as rotating actuators, air assist nozzles and
valves, special sensors, and pneumatic speed regulators. The
cutting module can be a standard type or one that has been
custom designed for a special application. Cutting modules
are easily interchangeable and additional cutting modules
can be used to expand the capacity and functionality of the
cutting machine.

ADVANCED SETTINGS SCREEN
The Advanced Setting screen (PHOTO 18) is used for
changing dwell settings, motor ramp and jog speeds,
air assist settings (when equipped), motor auto
reverse, and program saving. The Advanced Settings
Screen contains the following elements and function
descriptions:
Index Speed (%): Sets the maximum length motor
speed in percent (1% - 100%).
Cut Dwell (sec): Sets the cutting dwell time (in
seconds) for cutting through the material. Light
materials require less time than heavy materials.
Index Dwell (sec): Sets the dwell time (in seconds)
between from the end of the cut cycle to the
measuring of the next length. This setting allows a
melted end to cool.
Accel. Time (sec): Sets the time (in seconds) for the
motor to accelerate to full speed. A longer Accel Time
will allow the length motor to accelerate more slowly
and minimize roller slip, to improve length accuracy,
especially on heavy rolls or with elastic materials.
Decel. Time (sec): Sets the time (in seconds) for the
motor to decelerate before cutting. A longer Decel
Time will minimize material overfeed of heavy or stiff
materials.
Jog Speed (%): Sets the motor speed when the JOG
button is pressed on the main screen.
Air Assist (Length): (red switch & test button) An
optional function that uses compressed air to assist
the measuring of very lightweight and imsy materials.
When equipped with an air assist valve the air nozzle
will emit a blast of air through the knife to prevent
jamming and sticking of the material. Pressing the red
Test button will momentarily activate the air assist
valve.
Air Assist (Knife): (yellow switch & test button) An optional
function that uses compressed air to assist the removal of cut
material from the knife or anvil. When equipped with an air assist
valve the air nozzle will emit a blast of air off the knife. This
function has a dwell time setting below the yellow switch. Pressing
the yellow Test button will momentarily activate the air assist valve.
Auto Reverse: (blue switch) When activated, this function will
cause the feed roller to reverse briey before measuring. This allows
the motor to remove material that might have adhered to the anvil.
If the machine experiences jamming in the knife area, turn this
function on.
Program: (with left and right arrows) Program (recipe) settings
may be saved by pressing the gray Save Program button. To run a
previously saved program (recipe), toggle to the program number
using the arrows and press Load Program. Programs are saved by
number only. For detailed instructions, see the Appendix.
