I. DEBARKING

First of all the log is debarked to ensure that it has the good surface for peeling

 

II. PEELING AND CLIPPING

The log is sawn by peeling through rotation against a lathe blade, which lies against the length of the log. This produces a ribbon of veneer. The ribbon is cut to size by a clipping machine.

 

III. DRYING

The veneer goes through a drying machine to reduce its moisture content. This facilitates the bonding of the veneer afterwards

 

IV. GLUING AND JOUNTING

Small parts of veneer can be jointed into full-size sheets. This can be done by edge gluing, stitching or gluing paper adhesive tape. Afterwards, the veneers are sorted into different quality grades.

The veneer plies are assembled ("lay-up") through cross bonding: with the grain of each veneer at 90¡ to the adjacent veneer. They are glued together with a synthetic resin adhesive. The gluing process is supervised closely.

 

 V. PRESSING

The lay-ups are heated and pressed. A cold pre-pressing is applied to improve the quality and makes the pressing easier. Hot-pressing is done in high-temperature hydraulic presses.

VI. TRIMMING, SANDING (And Filming)

After the pressing, the panel is trimmed and, if necessary, surface defects are filled or repaired. Subsequently, most plywood is sanded, then cover face and back wood veneer (or film) to make a final plywood.

VII. PACKING AND LOADING

Standard packing or as required

Loading into containers by forklift.
