In a method and system for fabrication of roof trusses or similar structures wherein the structure is assembled from members to be set against each other and the members are fastened to each other by means of nail plates or similar fastening means, data defining the structure is produced for controlling the fabrication, one or more planes (T1) are defined for assembly of the structure and several grippers (100, 101, 103, 104, 106, 107, 115, 116) are arranged to move and rotate according to the control in said plane whereby the grippers form the basic part of an assembly line or unit (M) for the structure, the grippers are controlled to move and rotate to certain places and positions and said certain members (4) are set in the grippers to form on them a basic part of the structure, and the structure is controlled to move on the grippers for carrying out the other steps of the assembly process. |
