Machine Capacities: 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.

-6” Touch Screen Numeric Control switch board
-The Numeric control TS06 manage the machine and its functions.

Technical characteristics:
•6” graphic touch screen LCD display, 320x240 pixel.
•Glue Temperature control and auto temp kick-down
•WINDOWS CE Operating System
•USB port
•Auto “On & Off” of work units and work unit selections
•Automatic start-up of the units and motors foreseen by the programs.
•Button for direct selection of 2nd run without the need to access the menu.
•Managing of 8 numeric axis.
•Lists of programs with manual and/or automatic start-up.
•Error diagnostics with codes and comments.
•Production statistics.
•The device is installed on an adjustable overhead control panel

•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 ¼”) 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)

-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 Ø 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.
•E4000251 Edge pressure system “RPT” consisting of: First main driven roller, diameter Ø100 mm, with independent pneumatic pressure adjustment; 2 idle rollers, diameter Ø60 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.
