The Kontizink 2500 from Ledinek is part of a vertical finger jointing system for engineered timber laminations. Individual boards are positioned for end profiling before adhesive application and pressing. The interlocking fingers increase the bonding surface between successive pieces, allowing short lengths to become longer material for downstream processing. Coordinated handling helps keep the board ends aligned through the joining sequence. This type of line can support production of laminations used in glued timber products. Output and joint quality depend on the timber dimensions, adhesive process and machine configuration.
