ABSTRACT:
A truss assembly table having a plurality of sections in succession along its length separated by openings. Each section of the table has several panels in succession separated by openings which extend across the table. Below each opening between the panels, a lead screw drives a carrier which supports a jig stop projecting above the top of the table. Each lead screw is driven by a manually-controlled power-operated device for positioning the corresponding jig stop at a selected position across the table. Power-operated lifts at the openings between sections of the table can be raised to lift a completed truss above the top of the jig stops so that it can be slid off the table laterally.
