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 (Tl) 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.
L~invention concerne un procédé et un système de fabrication de fermes ou de structures similaires, selon lesquels la structure est assemblée en se servant d~éléments qui viennent se placer les uns contre les autres et s~attachent ensemble à l~aide de plaques à clous ou de moyens de fixation semblables ; la définition des données de la structure permet de commander la fabrication ; un ou plusieurs plans (Tl) sont définis dans le but d~assembler la structure ; et plusieurs pinces (100, 101, 103, 104, 106, 107, 115, 116) sont disposées de manière à se déplacer et tourner en fonction de la commande située dans ledit plan au moyen duquel les pinces forment la partie de base d~une chaîne ou d~une unité d~assemblage (M) destinée à la structure. Les pinces sont commandées pour se déplacer et tourner vers certains endroits et positions et certains dits éléments (4) sont disposés dans les pinces pour former la partie de base de la structure. La structure est commandée pour se déplacer sur les pinces afin d~effectuer les autres étapes du processus d~assemblage.
