Lamello's original wooden slat is the proven joining solution of the system's inventor. Since its invention in 1955, the lamello, also known as a flat dowel, has been used millions of times to join wooden workpieces. The success of the wooden slat is due to its simple, fast application, stable, high-quality connection, large longitudinal tolerance and minimal weakening of the material which is important for sheet materials. The original guarantees quality in the form of dimensional stability, optimum glue distribution, shape stability and high fracture resistance. Native, sustainable beech wood is supplied from the vicinity of the Bubendorf production site, where it is carefully sorted and processed. During stamping, the thickness of the wooden slats is checked several times an hour to ensure the right fit for the application. Thanks to this precise fit, the wooden slats fit easily into a 4 mm groove and do not fall out when the workpiece is turned over during assembly. The slightly raised guides on the flat dowel reduce resistance when sliding in and keep the joining element in the groove. The recessed surface is intended to provide a stronger compressed glue surface on which the glue can spread. As the glue cures, the wooden slat in the glued area expands further for an even more stable joint. The diagonal grain also ensures a very high fracture resistance. The rounded, smooth edges simplify insertion and increase comfort while working.

Applications

  • Precise wood joints in all corners in joinery
  • Ideal connector for sheet material, as the material is weakened less than with a dowel
  • Milling for joint sizes 0, 10 and 20 with the groove cutter Top21 or Classic X with 4-mm groove cutter
  • Routing for joint size H9 with the groove cutter Top21 or Classic X with 3-mm groove cutter
  • Blunt joints from a material thickness of 8 mm (H9 wood plywood)
  • Mitre joints from a material thickness of 8 mm (H9 wood plywood)

Properties

  • Perfect fit: The precision of the joining elements and the 4 mm groove ensure a perfect fit
  • Relief glue surfaces: Raised guide bars and embossed glue surfaces for optimum glue distribution and low resistance during assembly
  • Round edges: Easy to fit into the groove
  • Sliding tolerance in the profile groove: With the Lamello system, both workpieces can be aligned perfectly flat
  • Versatile: The small depth of the connector allows mitre cuts of 22.5 to 180°, such as for surface, corner and intermediate wall joints
