Abstract: A truss assembly apparatus for assembling truss structures, by assembly on two or more consecutive, spaced apart, coplanar work table surfaces and with a gantry type press assembly of a plurality of wooden truss members and truss connector plates with toothed projections, the truss members coupled by embedding the connector plate projections into said truss members. The truss assembly apparatus has a gantry type press assembly with first and second ends adapted to be mounted on first and second ends of each of said work table surfaces, for movement over the work table surfaces and the space between adjacent work table surfaces. The gantry assembly has a continuous belt on the first and second ends for driving of the gantry assembly, by engagement of the continuous driving belt with the first and second table ends. The gantry assembly is configured to be supported by the continuous belt, during movement of the gantry over a work table surface when crossing the space between work table surfaces.

Abstract: The device comprises a conveyor (1) for displacing the envelope, in a displacement direction (D), along a path including a bend, and a member (12) disposed on the outside of the bend and downstream therefrom in said displacement direction, said member (12) cooperating with the conveyor (1) to cause the envelope to curve around the bend, and being movably mounted relative to the conveyor, so as to move a certain distance away from the conveyor depending on the thickness of the envelope and on its stiffness. A sensor (30) is provided to detect said certain distance minus the thickness of the envelope exceeding a predetermined threshold, thereby detecting that a hard object is present inside the envelope. The present invention applies to the processing of mail items.
