Device for assembling hollow and tapered wooden sections by the use of six, eight or ten elements 1 bearing on shoulders at 90 DEG and automatically nesting together under the effect of a tourniquet. The assembly is produced by bundling up these sections produced with tourniquets which, once tightened, give the pressure necessary for bonding. Depending on the size of the work produced, the tourniquets will be made with rope, textile strap, metal tape or, for the largest ones, with nylon tube similar to the water hoses used by firemen which we will fix as a spiral around the work during bonding, and tightening will be obtained by passing pressurised water or air in. <IMAGE>
