In the production of finger-jointed details, it is most important to provide the required applied pressure to achieve the desired adhesion strength of the joint. The results of the study of beech wood elements (Fagus Sylvatica) are presented, with applied different pressure for the face ends of the details (0,4 and 0,7 N/mm2). The following properties have been determined of the tested samples: bending strength, modulus of bending elasticity and the density of the tested wood. The pneumatic-piston system is also provided for securing the bonding pressure in the longitudinal direction of the wood. In the carried-out experiments, it was used a polyvinyl acetate adhesive with a class of water resistance D3 was used. |
