E550 - E550 CR - E550 PM - E550 PM CR Automatic Single-Side Edgebander Rel. 1.1.1
3.5.1 INTERCHANGEABLE GLUE POT PUR/EVA (OPT)
Technical characteristics:
Heating elements: 5 heating elements for Teon coated glue pot + 1 heating element for spreading roller
Heating time from ambient temperature approx. 14–16 mins. (EVA) 40-45 mins. (PUR).
Heating time from standby: 5-6 mins.
Glue pot capacity approx.0.5 kg
Operation
The purpose is to spread hot melt glue on the panel to be edged.
The part of the PLC dedicated to thermoregulation controls the heating and operation of the glue pot as
soon as the main switch is placed in ON.
Follow these instructions for correct operation:
1) Open lid G and ll the pot with hot melt glue pellets up to about 1 cm beneath the edge of the pot
(A, Fig. 3.5).
Take care that the type of glue used is compatible with the technical characteristics of the machine.
Recommended EVA glues
Jowat JOWAT 280.50 200°C
Emmebi International Type of glue equivalent in density/temperature to JOWAT 280.30
DORUS Type of glue equivalent in density/temperature to JOWAT 280.30
Recommended PUR glues
Jowat JOWAT 608.00-86G granulate 500g pack.
2) Working temperature SP1 must be set to the temperature recommended by the manufacturer
(EVA glue factory set at 200°C; PUR glue factory set at 130°C;).
3) The spreading roller tted with an internal heating element automatically starts to rotate, and the
machine can be started when the glue reaches AL = SP1-10°C rotating element B after having loosened
screw C.
The quantity of spread glue is adjusted with knob D, increasing it in a clockwise direction or reducing it in
an anticlockwise direction. After adjustment tighten screw C.
Check the level of the glue in the pot and if necessary add up to the level indicated in point 1).
“AL” is calculated by the PLC, which automatically subtracts 10°C from every value set for SP1.
Example: Working temperature SP1 = 200°C, therefore AL = 190°C.
IMPORTANT NOTE: The working setpoint (SP1) must be set according to the characteristics of the used
glue.
Otherwise there is the risk of breakage of mechanical and/or electrical components of the glue spreading
roller.
We suggest starting edging operations 5 minutes after the glue pot has reached the required temperature
of 200°C.
When temperature SP1 has been reached and with the feed halted, after 10 minutes the machine moves
into STANDBY, and the PLC sets the temperature to SP2 (factory set at 150°C).
To exit from the STANDBY function, press SP1 or button 6.
4) The knurled plastic knob (D) is used to exclude the glue pot. The knob is screwed in at the factory to
avoid damage to the glue pot during transport.
To use the machine, unscrew the knob completely up to locknut E.
Nut E is factory adjusted, and its position must NOT be changed for any reason whatsoever.
When one works with PUR glue, for an optimal use, try and work continuously with few and short breaks.
This is the reason why we recommend the purchase of 0.5 kg packs.
Once the work has been completed the pot must be emptied and for inactivity periods longer than 3 days
apply the cleaning agent 930.74.
Maintenance: lubrication, replacement of burnt glue, replacement of burnt out heating elements
Lubrication must be carried out with the machine turned on and with the roller rotating. The operation is
performed with the grease KLUBER barrierta 155/2.
IF LUBRICATION IS NOT CARRIED OUT, THE GLUE POT CAN BE DAMAGED IRREPARABLY, AND
ITS REPAIR WILL NOT BE COVERED BY THE GUARANTEE.
To remove the glue from the tank, turn the selector X (for glue roller rotation) and remove the glue from the
roller with a spatula.
