Mounting Of The Sliding Support; Description And Start Up; Temperature Control; Straight Edging, Trimming And Flush Cutting - Virutex eb25 Operating Instructions Manual

- Position the support W1 and secure it using the
screws U1.
- Position the tape loader B, ensuring that it turns
freely.

3. MOUNTING OF THE SLIDING SUPPORT

In order to mount this sliding support assembly the
following procedure should be observed (Fig. 4):
- Remove from the sliding support guide J, screw K
which holds the peg L at one of its ends.
- Position the sliding support S and reassemble to its
previous state.
- Level the sliding support S with respect to the table
using a ruler and by adjusting screw K.
- Proceed in an identical manner with the other sliding
support guide.
- Check the correct sliding of the assembly inside
the guides.

4. DESCRIPTION AND START UP

The machine has a safety switch (on-off) A on its
right-hand side (Fig. 5).
This is to safeguard against unexpected start-ups as
well as a for connecting the machine and electrical
overload to the mains. This should be carried out by
means of an extension cable with conductor and
earth, using conductors suitable for a nominal
intensity of 16A.
Next to the loader B, (Fig. 5), are the machine
remaining controls (Fig. 6), which consist of an
emergency switch C, on-off switch for the heater F,
on-off switch for the feeder motor D, indicator light E
showing on-off status of the machine and a regulating
button G to adjust the temperature of the heater.
To start up the machine, press the green button R1
(Fig. 5) to supply voltage to the machine. Pilot E lights
up. Then flick heater switch F and feeder motor swit-
ch D to On. If the machine receives an electrical
overload, switch N1 will be deactivated, cutting off
the supply voltage. In order to re-establish supply, it
will first be necessary to flick thermal switch N1 and
repeat the above steps.
If the emergency switch is used, this immediately
deactivates all the machine functions, making it
necessary to reset this switch by turning it in the
direction f the arrow and to press the green start-up
switch (Fig. 5) in order to recommence work.
Place a roll of pre-glued tape in loader B (Fig. 5).
Its width must correspond to the thickness of the
board to be edged; we recommend using a tape 3
mm wider than the board's thickness in order to
achieve perfect trimming.
Place the pre-glued tape in the tape guide and adjust
the height of guides I (Fig. 8) to the width of the tape,
using knob J, which raises or lowers guide I, and
ensuring that the tape moves smoothly.
Move the tape manually to the cutting edge and pla-
ce a panel on the table, supporting it on the front of
control box U (Fig. 9), and move it over the milled
roller to check that the tape is moving smoothly
between the guides.
If no obstacles are observed, move the tape back as
far as the cutting edge using knob K (Fig. 8), ensuring
that the tape is moving correctly against the panel.
Close the feeder and start the machine by pressing
the green on-off button R1 (Fig. 5).

6. TEMPERATURE CONTROL

Before carrying out this operation it is important to
take the precaution of checking that the tape is not in
front of the air outlet from the blower L, (Fig. 9) to
prevent it overheating and thus damaging the pre-
glued tape. Start the heater by moving switch F (Fig. 6)
to position 1.
To raise the temperature more quickly, turn the
electronic control G, (Fig. 6) to number 9 on the con-
trol scale and watch the temperature rise quickly.
Once it has reached 300°C turn the knob to point 5
on the scale and once the needle has stopped
moving, the temperature can be adjusted to the
correct level for the pre-glued tape we are using.
7. STRAIGHT EDGING,
TRIMMING AND FLUSH CUTTING
The machine leaves the factory prepared for this type
of work and the only adjustments needed are for the
pre-glued tape width and the width between the
trimming blades for the panel to be banded (the
adjustment for pre-glued tape width has already been
explained in section 5. ASSEMBLY AND START UP).
To adjust the trimming blades and place them in
working position follow the instructions in the section
on 11. ADJUSTING THE BLADES (Fig. 10).
The minimum measurements of panels for this edging
work are the following:
Minimum width 102 mm and 175 mm minimum length.
8. REGULATING EXCESS TAPE AT REAR
When banding, if there is an excess or lack of pre-
glued tape at the rear, the tape can be adjusted
moving lever M1 (Fig. 19) slightly to the right or left
according to the indication (+,-) on the machine.
9. CLAMP ASSEMBLY
The machine is equipped with two clamps X, (Fig.
13) fixed to the extension guide S, which push the
panel from the side of panel on rollers.
It is advisable to place clamp X on the left of the
extension guide S, i.e. at the feeder outlet, to ensure
correct trimming.
10. CHANGING THE TRIMMING BLADES
For ease of access to the motorised trimmer open
the feeder by loosening handle H, (Fig. 7).
Remove all of the protection devices which cover the
unit by removing the three screws Y on each side,
(Fig. 9).
Remove screws Z which secure the belts unit to pulley
W and remove the pulley, (Fig. 14).
Remove screws A1 which hold the blades in place,
