For high-quality gluing of lumber in to a log, it is extremely important to ensure high quality of the surfaces which will be glued together. So after splitting the tree, the lamellas are fed into a four-side planer. It provides both sides with equally smooth surface. Our factory uses presses specially designed for gluing a wall beam, as only they are able to provide a uniform pressure on the surface in the amount of 16 kg / m2 for large sizes. After exposure in the press, according to the technological map, the finished semi-finished beam enters the warehouse, where it spends 72 hours for the final crystallization of the adhesive composition.
