ABSTRACT:
The invention discloses a method and apparatus for squaring wall panel assemblies prior to nailing sheathing material thereto. A preformed wall section having a frame and studs has a sheathing member placed thereover and fastened thereto whereby said components form a prefabricated wall section. To ensure that the assembled wall section is square the assembly line has squaring stops positioned on each side of the guide track. These stops are engineered to be in alignment with each other and causing the workpiece to form two right angles prior to release for nailing.
