been carried out correctly.
If the fi nish is not entirely satisfactory on any of the edges, wha-
tever small readjustments are necessary can be made using
knob Y (Fig. 9) to adjust the upper or lower copying devices C2
(Fig. 9), until the correct fi nish is achieved.
Upper
Adjusting the scrapers:
The scrapers should be adjusted to suit each type of board,
always after the trimmers have been regulated.
To regulate the scraper, turn knob A1 (Fig. 10) until scraper I2
(Fig. 10) lightly rubs against the board, honing the joint between
the board and the edging.
The lower scraper is accessed using front door F3 (Fig. 14) of
the machine. Proceed in the same manner.
Regulating excess edging at the back:
If when edgebanding a board with front and back cutting fl ush
with the board there is too much or too little edging at the back,
the cut can be adjusted so that it is fl ush, by giving the lever
A2 (Fig. 25) a slight turn in the direction required. Turn towards
the "minus" (-) mark for less excess and towards the "plus" (+)
mark to increase the amount of excess.
9. HOW TO USE THE EDGEBANDER
• EDGEBANDING EDGES UP TO 1mm
Position of the controls:
Lever A (Fig. 6) in position 1, for 1-mm edges
Switch CM1 (Fig. 6) in position 1, front and back cut fl ush with
the board
Switch CM2 (Fig. 6) in position 1, feeder and heater on
Switch CM3 (Fig. 6) in position 1, trimming both sides of the
board
1. Place the board on the machine. Press on front panel S (Fig.
5) of the control box and move towards the feeder so that it will
take in the board and convey it automatically.
2. When the board presses on micro-switch B (Fig. 21), automatic
feeding of the edging begins.
3. When the board reaches micro-switch E (Fig. 21), automatic
feeding of the edging is interrupted. This continues being dra-
gged by the board, and the trimmer and dust collector AS382L
(if connected) start up.
4. As the board reaches blade H (Fig. 21) of the front cutting,
it moves it forwards and cuts the excess edging. Front cutting.
5. When the back end of the board releases micro-switch B (Fig.
21), the edging is cut. Rear cutting.
6. The trimmer stops when the back end of the board releases
micro-switch F (Fig 21). The dust collector also switches off
after a few seconds.
The edgebanding cycle is complete when the board has fully
exited the feeder.
• EDGEBANDING THICK EDGES OF 2, 3 MM
Before making any adjustments, change the position of the
approach roller B2 (Fig. 27 and Fig. 28), lock it with the rod C2
and unscrew the knob D2. Switch the position of rollers B2 and
E2 and remount in the inverse order (Fig. 28).
Lower
• EDGEBANDING EDGES OF 2 mm
Position of the controls:
Lever A (Fig. 6) in position 2, for edges of between 1 and 2
mm
Switch CM1 (Fig. 6) in position 1, front and rear cutting fl ush
with the board
Switch CM2 (Fig. 6) in position 1, feeder and heater on
Switch CM3 (Fig. 6) in position 1, trimming both sides of the
board
The working cycle of the edgebander for this type of edging is
identical to that set out in EDGEBANDING EDGES UP TO 1
mm, as explained above.
• EDGEBANDING EDGES OF 3 mm
Position of the controls:
Lever A (Fig. 6) in position 3, for edges of between 2 and 3
mm
Switch CM1 (Fig. 6) in position 4, cutting the edging with excess
at front and back
Switch CM2 (Fig. 6) in position 1, feeder and heater on
Switch CM3 (Fig. 6) in position 1, trimming both sides of the
board
1. Place the board on the machine. Press on front panel S (Fig.
5) of the control box and move towards the feeder so that it will
take in the board and convey it automatically.
2. When the board presses on micro-switch B (Fig. 21), automatic
feeding of the edging begins.
3. When the board reaches micro-switch E (Fig. 21), automatic
feeding of the edging is interrupted. This continues being dra-
gged by the board, and the trimmer and dust collector AS382L
(if connected) start up.
4. When the board triggers micro-switch G (Fig. 21), blade H
(Fig. 21) of the end cutting unit retracts to let the board pass
through without front cutting.
5. When the back end of the board releases micro-switch B (Fig. 21),
being switch F (Fig. 21) pressed, the rear end of the edging is cut.
6. The trimmer stops when the back end of the board releases
micro-switch F (Fig. 21), and the dust collector also switches
off after a few seconds.
When micro-switch G (Fig. 21) is released by the back end of the
board, the blade of the front cutting is free to return to its initial
position when the board has passed through. The edgebanding
cycle is complete when the board has fully exited the feeder.
• FRONT AND REAR COMBINED CUTTINGS
WARNING!
Never try to raise the protector when the machine is carrying
out a front cut. The blade is very dangerous and could easily
cause an accident.
Front and rear cutting fl ush with the board: (For edging of up
to 2 mm thick)
Switch CM1 (Fig. 6) in position 1.
1. When the back end of the board releases micro-switches B and
C (Fig. 21), being micro-switch D (Fig. 21) pressed, the edging
is cut at the back, fl ush with the board. Rear cutting.
If the rear cutting is not fl ush with the board, see Regulating the
excess at the back of the edging to correct the fault.
2. When board front reaches the blade H (Fig. 21) ,it moves it
forward and the excess edging at the front is cut fl ush with the
board. Front cutting.
Front cutting fl ush with the board and rear cutting with excess:
(For edging of up to 2-mm thick)
