More closely, the invention concerns a system for fabricating roof trusses or similar structures from members to be set against each other, the system comprising several grippers arranged at a certain assembly plane to be steered into certain places and positions for certain members for forming a structure on them and means for controlling the operations of the system as well as means for carrying out said controlled operations.
  • Roof trusses or similar structures are usually fabricated on a horizontal platform.
  • a pattern or jig is realized in one way or other which helps to place the members in place.
  • the chords and diagonal members are usually set manually on the platform according to a pattern and fastened then to each other by means of nail plates.
  • the system presented by the applicant comprises as a whole e.g. the following steps and the corresponding apparatuses: - feeding the members (pieces of wood) of a structure and setting them in a controlled order at certain places to be picked up,
  • FIG. 1 presents a schematic example in which grippers C and guides D have by means of suitable technical devices been arranged to be moved and rotated according to control on a post B moving on rails A.
