Abstract
Abstract The fabricating apparatus comprises a jig table carrying wooden framing members positioned to form a truss. Nailplates are located on opposite sides of the butt joints of the wooden members for embedment into the joints by a press movable lengthwise along the jib table. The jib table is supported by a plurality of longitudinally spaced pivoted wands comprised of substantially U-shaped members. One leg of each of the pivoted wands engages the undersurface of the jib table to support the latter while its opposite leg lies below the lower press platen and bears against a support preventing pivotal movement of the wand from its table supporting position. As the press traverses the table, the lower press platen successively pivots the wands to locate the other legs of the wands in supporting engagement with the jig table while the previously supporting legs of the wands are pivoted below the lower press platen. The pressis controlled via a circuit responsive to switch actuating pins disposed at selected positions along a track for automatically and sequentially stopping the press when the press overlies successive butt joints, actuating the press to embed the nailplates, and restarting the press for movement along the jig table.
