Narrow side bonding
Narrow side bonding vs.
flat crosswise bonding
By gluing the individual layers crosswise, the shrinkage and swelling of the entire panel is significantly reduced and the component is more dimensionally stable, but each individual lamella in the cover layer can still shrink slightly, hindered by the layer below. This may result in a small joint of < 1 mm in the cover lamellae.
However, if narrow side bonding is present, this process can lead to unplanned cracks within the individual boards.
