ABSTRACT:
An assembly jig for fabricating wooden trusses including a moving jig platform on which toothed metal gusset plates are placed; wood truss component members assembled with each joint of the wooden member placed over the plates, toothed metal gusset plates placed on the upper side of each joint, and a series of three sets of small diameter pressure rollers press the plates flush into the wooden members when the moving jig platform moves the truss through the pressure rollers. A slide plate between the first two sets of small diameter rollers prevents curling of the plate partially pressed into wood members passing therethrough, and the third set of rollers completes the embedding of the teeth in the truss.
