ABSTRACT:
A building truss fabrication apparatus in which a plurality of press head assemblies are supported by an overhead gantry support so that the various press assemblies are movable in an x-y coordinate space. A movable jig table is arranged to move between an assembly position and a pressing position within the apparatus. The movement of the jig table is hydraulically powered as are the press head assemblies. The entire apparatus is operable by a single hydraulic power source. A standard air compressor is used to generate air pressure of pneumatic clamps used on the jig table. The pneumatic clamps are part of the jig fixtures which hold lumber components into a truss preformed shape. Connector plates or nail plates are pressed into the component ends by the press head assemblies in order to complete fabrication of the building truss.
