Manufacture of trusses

Abstract

A plurality of wooden roof trusses for constructing a roof includes first and second wooden roof trusses. Each of the first and second wooden roof trusses includes a bottom chord and at least one upper chord obliquely disposed relative to the bottom chord. A first web is provided to the first wooden roof truss and a second web is provided to the second wooden roof truss. Each of the first and second webs has a tapered web end shape set without regard to a shape of a first and second joint, respectively, into which said tapered web end shapes of the first and second webs fit. The first and second webs are substantially identical in length and web end shape. The first and second webs are located at different positions in their respective first and second wooden roof trusses.
