8.10.1 Function
The feeding system of panel to be edged is made up by
a chain with rubber inserts and a top adjustable pressure
bar, equipped with a double line of rubber rollers.
The glue spreading roller, the small edge feeding roller
and the pressure roller are powered by chain feeder,
therefore the rotation of the rollers function only when the
temperature of the glue pot is over 190°C and the button
has been pushed to start up chain feeder.
The rising system is made up by two worm screws, and
sliding is effected by two rectified columns.
The feeding speed is 9 mt/1’ and allows a good produc-
tivity and perfect gluing. When the panel which is being
edged passes the arrow on the protection guard of the
pressure bar, then the next panel to be worked can be
put through.
If this measurement is not respected the working cycle is
altered and the panels damaged!
If this should occur it is necessary :
• immediately stop the machine with emergency push
button
• lift the pressure bar with wheel handle
• take out the panel
• RESET the machine positioning the main switch on
OFF and then straight away on ON
Adjust the height of the pressure bar in regards to the
panel thickness to be edged with the wheel handle 2 fig.
40 and read measurement on the numerical indicator 1
fig. 40 Always adjust the height “upwards” to recuperate
play.
The plastic plate 3 fig. 40 functions as a “thickness
limit” of the panels to be edged. If by mistake a panel of
higher thickness is fed through the plate 3 activates an
Fig. 40: Chain feeding unit
emergency micro switch which stops the panel feeding.
To get the feeding working again just press the button of
the panel feeding.
When altering the height of the pressure bar, the height
of the upper trimmer, the upper edge scraper and the
upper buffing unit are also regulated.
