Biesse Akron 425 AN

The AKRON 425AN is an automatic single sided edgebanding machine for the application
and processing of flat edgebanding material in coils (melamine, PVC, ABS, veneer)
and in strip form (solid wood, Formica, planed veneers etc.).
Innovative technology, solid operating work units and heavy duty construction are combined
to ensure a high quality finish and great reliability under a wide range of working conditions.

STRUCTURAL COMPONENTS :
Base: I-BEAM FRAME provides the whole machine and work units, with stability and strength to allow precise, accurate machining.
Integrated automatic chip removal system along the whole machine.
Panel movement: provided by a conveyor large industrial track pads and heavy duty
Top pressure beam, combining a system that ensures optimum hold-down of the panel being processed,
straight movement and resistance to side loads resulting from the forces when applying the edges.
The conveyor Track utilizes an industrial chain with a 31.75 mm ( 1 ??) ratio, with track pads made from a special self-lubricating techno-polymer.
The Track pads slide on two hardened steel guides, one with a circular section and the other one flat,
complete with grease fittings for easy maintenance.
The panels being edged are held by special low wear rubber pads with a high friction coefficient, which are individually interchangeable with a quick change system. (Pad dimensions are 80x60 mm).
Main Gear motor for feed chain.
Working speed: 13 meter/min 1.5 kW motor.
The Heavy duty
Top presser beam, with high rigidity, allows the constant change of the panel thickness
without any manual set-ups or interventions on the operating units.
The panels being edged are held in position by a double row of rubber staggered wheels with 32mm center to center spacing and mounted on precision bearings.
The top working units are attached to the top presser and adjust automatically with the positioning of the top pressure beam itself.
The top pressure beam movement is a centralized, with manual positioning via hardened steel guides and bushings.
Lateral sliding panel support on bearings.
It includes extruded aluminium guide complete of support wheels. Quick manual positioning and locking system.
Full protection safety hood covers the entire length of the machine.
It is made of extruded aluminium frame work with wide open surfaces in transparent polycarbonate for the complete view of the operating units.
Centralized dust extraction connection. (150mm)

WORKING UNITS -GLUING, EDGE FEEDING AND PRESSING UNIT VC-511:
Applies the hot melt glue onto the panel, feeds the edge to be applied to the panel being machined, automatically cuts the rolls
of edge-banding material to length and presses the applied edge ensuring that it adheres perfectly to the panel.
The system includes: ?VC-511R Glue reservoir and glue spreading roller.
The spreading roller is complete with a copying system to apply the correct amount of glue to the panel.
The manual glue spread adjustment (dual position) for quick change.
Manual device for the quick exclusion of the glue reservoir.
No adjustment required when the panel thickness changes.
Quick heating and double thermostat control for proper temperature control.
The glue reservoir is completely coated with non-adhesive material for ease of maintenance.
Automatic glue temperature lowering in the glue reservoir when the machine has been idle for a set period of time.
Glue roller application rotating in the same direction of the panel feed.
Quick change of the glue reservoir for an easy maintenance or color change / type of glue.
Automatic Edge feeding system for edges in coils and for edges in strips, complete with: roll holder disk diameter ? 800 mm.
The edge magazine table has a manual vertical adjustments for ease of set-up.
Coil guillotine knife for the automatic cutting of edge-banding material in coils with a maximum thickness of 3 mm and with a maximum section of 140 mm2.
Manual and fast adjustment of working pressure according to the thickness of edge-banding material being used.
The guillotine is positioned prior to the 1st main edge pressing roller.
Edge pressure system RPT consisting of: First main driven roller, diameter 100 mm,
with independent pneumatic pressure adjustment; 2 idle rollers, diameter ?60 mm, coated
with non-adhesive material with pneumatic adjustment; they are opposing conical cones
Edge pressure rollers with temporized intervention.
It does not require adjustment when changing the thickness of the edge to be applied and its thickness is between 0,4 and 3 mm. When using edges with thickness larger than 3 mm the adjustment is manually performed.

END TRIMMING UNIT / Pneumatic Tilting on PRISMATIC GUIDES IN-501V ( 2 motors 0,5kW each) HSD Electro Spindle Motors.
Carries out the trimming on the ends of the panels to remove excess at the front and rear portion of the panel.
The cut can be accomplished straight (flush) or tilted (bevel) with a cutting angle between 0 and 15 degrees: the cutting angle via Pneumatic tilting from the control panel
Degree displayed on a scale.
Great reliability and precision due to the sliding on large prismatic
Linear guides and heavy duty precision sliding bearing blocks.
Fast tilting of the motors from 0 to 15 degrees
Manual positioning Working exclusion from control board.
Equipped with 2 high frequency motors (0,5 kW each) at 12.000 rpm complete with carbide tip saw blades.
