Abstract
A truss assembly apparatus for simultaneously rolling opposed toothed metal connector plates of V-webs onto both sides of vertically spaced horizontal wood chords. A prefabricated wood frame of such chords with end and intermediate spacers is fed between parallel vertical axis powered rollers with the V-webs manually applied to each side ahead of and as the frame is compressively driven through.
Claims34
Truss assembly apparatus for securing toothed connector plates to sides of vertically spaced wood chords comprising vertical axis longitudinally fixed roller means for progressively pressing said connector plates with teeth placed against said chords ahead of said roller means into wood penetrating assembled relation as they pass said roller means, means for maintaining said chords in required spaced relation, and means for driving said chords in said required spaced relation together with said connector plates past said side roller means.
A production method for assembling trusses constructed of spaced parallel wood chords connected by stamped sheet metal elements having toothed extremities fixedly penetrating said wood chords comprising the steps of prepositioning said chords in parallel vertically spaced relation, positioning the extremities of said elements on respective horizontally spaced sides of said wood chords in required spaced relation to each other, driving and guiding said chords along a horizontal path, and applying synchronized compressive rolling pressure adjusted to the width of said chords to progressively force said toothed extremities into penetrating assembled relation along the length of said wood chords.
