Manufacturing process

Wood sorting

In the course of pre-sorting, wood lamellae are carefully examined for defects 

Wood drying

Requisite equilibrium moisture content of 10 to 11 per cent is achieved in drying chambers and air conditioned halls

Finger jointing

Finger joints are milled at the ends of the boards and the glue is applied 

Gluing and pressing

Gluing to "endless lamellae" – At WIEHAG, curved glulam beams are always glued in a unique CNC-controlled press bed, and straight members in hydraulic presses


Finally, CNC joinery and manual trimming are performed. The fully automatic Hundegger joinery machine delivers precise and flexible processing. Client specifications related to aesthetics, shape and accuracy are achieved through manual trimming, sawing, planing and milling
