Safety systems and messages.
This die cutter has been equipped with the following safety systems:
1- EMERGENCY STOP
This system allows an emergency stop to be performed at any time using the two push
buttons located at both ends of the bench.
MESSAGE: EMERGENCY BUTTON PRESSED
To deactivate it, we must unlock the push button and then press RESET to return the head to
the starting point.
CLAMP OPEN
This device does not allow engagement of the cutting head if the bar holding the belt is not
lowered.
MESSAGE: CLAMP OPEN
To deactivate it, all we need is to lower the bar and press START.
3- DOOR OPEN
This device detects that the rear door of the blade head is open.
MESSAGE: COVER OPEN

Use and maintenance manual

Model: DC-200
____________________________________________________________________________________________________________________
P a g . 8
The door must be closed to deactivate it.
4- CYLINDER DETECTOR
This device does not allow displacement of the head because it detects that the cutting
cylinder is not raised. This may happen due to lack of air or failure of the detector.
MESSAGE: CYLINDRE WRONG
To deactivate it, provide the machine with air or replace the detector.
Programming
We must know the functions of the push buttons on the board to program the die cutter.
1- RESET
This must be pressed after an emergency stop or position the head at the starting point after
STOP.
2- A-A
- Selection of the A-A program
This program is used in the majority of cases, to always operate on the left guide rail and cut
the belts performing the first end with the coverage on top and the second end with the
fabric on top, both for direct finger die cutting as well as finger over finger die cutting.
3- A-B
- Selection of the A-B program
This program is only used in cases of diagonal belts, or belts with an hi profile, to operate the
first end on the left guide rail and the second on the right guide rail, always with the
coverage on top.

On pressing START, it will continue the process without losing the positioning memory
5- START
Starts the cutting process or acts to reboot following a stop.
6- WIDTH
We shall use this button to program the width of the belt in centimetres with the numerical
keyboard, to accept the number entered push ENTER.
7- STEP
We shall press this button to program the cutting process by means of the head assembled,
with the numerical keyboard, introduce the value in milometers, between 3mm to 50mm, to
accept the numerical value, press ENTER
8- TIME
We shall press this button to program the cut time using the numerical keyboard the
numbers accepted are between 3 to 10, to accept the number press ENTER

We then mark the measure to input the relevant material with a pencil, according to the die we
want to use.
We then place the belt under the tread bar until the mark made matches up with 0 Ref. and we

We select function A-A if it is not activated.
We press WIDTH to input the numerical value of the width of the belt in centimetres and accept
pressing ENTER.
We check that the STEP is correct. If it is not, we use the STEP key and input the desired value
after ENTER.
NOTE: The values programmed shall not be lost, even when the equipment is switched off;
the program always memorises the last values input.
We press START to begin cutting at the first end.
NOTE: During the cutting process, no programmed value may be changed, except the
cutting time. To do so, we press STOP and change that value pressing TIME, modifying the
cute time and accept pressing ENTER.
After we press START to continue.
Once the first cut is completed, we release the belt by pressing the raise bar button.

We place the second end of the belt on the left side by the guide rail, but the opposite way, that is,
with the coverage down, and position the end of the belt just on the O Ref. mark.
Then mark the measurement to feed in the material with a pencil, according to the die one
wishes to use.
We then feed in the belt under the holding bar until the mark made aligns with 0 Ref. and we
make sure it is fully in contact with the guide rail.

We lower the tread bar using the down push button and press START.
Once the operation is completed, we release the material by raising the tread bar.
DIE CUTTING A-A Finger over finger
NOTE: For this type of die cutting, one requires prior separation of the fabrics with the ply
separator device PS-15
Separate the fabrics of the 130 mm. belt at both ends.
We mount the 50x20 mm die.
We check that the A-A function is activated.
We program STEP 20 mm. and the required width in centimetres.
We shall regulate the pressure to 3 bar, as the cutting pressure is less due to the length of the
blades.
We place the first end of the belt on the left side, by the guide rail, and place the end of the belt
just on the O Ref. mark.

Then pencil mark the two measures to insert the material for the stops STEP-1 and STEP-2.
We then insert the material up to the first mark STEP-1.
We lower the tread bar using the push button to lower it and press START.
Once the first cutting operation has ended, we shall withdraw the surplus material.
We shall place the anti-cut plate between the two cloths up to the end of the separator cut.

Once the anti-cut plate has been placed inside, we insert the material up to the second mark
STEP-2.
We reduce the cutting pressure to 2 bar, as the second cut shall only cut the top fabric.
We lower the tread bar and press START.
On finishing the second cut, we withdraw the surplus material and the anti-cut plate.

We place the second end of the belt with the opposing face upward on the same left side and
repeat the same operations.
DIE CUTTING A-B for High profile belts at 90º
We select function A-B if it is not activated.
We mount the die chosen: 80x10 or 120x15.
We program the relevant gauge for the die mounted and program the width in centimetres.
We adjust the cutting pressure according to the hardness of the belt and the blade length.
First, we place the first end of the belt on the left side by the guide rail and then position the end
of the belt just by the O Ref. mark, in order to mark the relevant material insertion measurement
according to the die we wish to cut with.

We then place the belt under the holding bar until the mark made aligns with 0 Ref. and make
sure that it is fully in contact with the guide rail.
We lower the tread bar using the down push button.
Using the + / - buttons, we adjust the belt width in centimetres and press OK.
We check that the STEP is correct and, if that is not the case, using the MENU key, we jump to the
field STEP and input the desired value with + / - and then OK.
We press START to start cutting at the first end.
Once the first cut has been performed, we observe that the head shall be positioned at point 0 of
the end opposite the control board. On reaching that point, we release the belt by pressing the
bar up button.
We place the second end of the belt on the right side next to the right guide rail and, with the
coverage also on top, we position the final end of the belt just at the O Ref. mark, to pencil the
mark with the measurement for insertion of the relevant material according to the die we wish
to cut with.

DIE CUTTING A-B Diagonal 70º
We select the A-B function if it is not activated.
We mount die 80x10 70º.
We program the STEP to 10mm.
We adjust the cutting pressure to 4 // 6bar
We program the width in centimetres 10% wider than the belt width.
Example: if the belt is 400mm. wide, we will program 44 instead of 40.
We remove de diagonal guide of right side and place in the left side.

Once the first cut is complete, we note that the head will be positioned at point 0 of the opposite
end of the control board. On reaching that point, we release the belt by pressing the raise bar
button.
We place the second end of the belt on the right side, by the right diagonal guide and with the
coverage also on top, and position the far end of the belt just at the O Ref. mark, to pencil the
measurement mark to insert the material, that will be 80x10 70º.
We then insert the material till the mark aligns with 0 Ref. and lower the tread bar and press
START.
Changing die head
WARNING:
When changing the die, it is recommended to turn off the equipment with the OFF switch
for greater safety.
We open the rear door.
We loosen the 2 bolts using a 13mm Allen key.
