Abstract: An integrated system for fabricating the wall section for a building. The wall section includes a framework composed of plural studs disposed in a parallel array between an opposed pair of plates and has sheathing secured over the framework. The system comprises a first workstation including a frame for supporting the studs and a frame for supporting the plates in abutment with the ends of the studs. Automatic nailing means are supported on a carriage which is movable along the frame and is operative to nail the abutting stud and plate portions together. Portions of the frame means are retractable to enable a conveyor to move the framework, once assembled, to a second workstation. The first workstation also includes cutting means mounted on a carriage for cutting off excess end portions from the opposed plates extending beyond the most upstream stud of the wall section. The second workstation includes a conveyor for receipt of the assembled framework.
