Abstract: In the method, grippers (110, 140) are placed on a stationary assembly table (100) and rod-like members forming a wooden construction are laid on the support of said grippers. The wooden construction can be for example a roof truss or a wall frame. The assembly table comprises a vertical fastening plane (104) to which the grippers are fastened. The fastening plane can be made of ferrous material and the grippers can be fastened to the fastening plane magnetically or by means of a suction pad gripper. The fastening of the grippers to the fastening plane, the fastening of the rod-like members to the grippers and the joint connecting the rod-like members are conducted by means of an assembly robot (200). The joint may be a nail plate joint, a nail, screw or staple joint or a glued joint. From the CAD file of the wooden construction a list of commands controlling the operation of the assembly robot is generated by means of a decompression program.

Abstract: A method comprises manufacturing a frame of a C-clamp, which has a lower jaw, an upper jaw and a mouth between the lower jaw and upper jaw. The method comprises forming a lower end plate and an upper end plate and at least two frame plates, which have a lower branch and an upper branch. The lower branches of the frame plates are attached to the lower end plate and the upper branches to the upper end plate, so that the frame plates settle in a parallel manner at a distance (e) from each other. The joined frame plates and end plates form the frame of the C-clamp. The frame plates are formed by machining a steel plate of ultra-strength steel only with machining methods, which do not substantially heat up the material being machined. Suitable machining methods are for example chipping machining methods or water cutting. The lower branches are attached to the lower end plate and the upper branches are attached to the upper end plate by welding or with mechanical attaching means.
