ABSTRACT:
A machine for forming beveled webs, particularly for use in truss structures, includes a feed table upon which a wooden board is placed. A saw is shifted into cutting relation with the board to sever a web which drops into a hopper. A pusher displaces the web from the hopper and along a guide surface and eventually forms a row of webs which is pushed toward a beveling station. At the beveling station, a pair of cutters are situated at opposite sides of the guide surface and each include co-axially arranged router heads. The router heads are of frusto-conical configuration and form a cutting angle through which the webs pass. Top and bottom bevels are cut in the ends of the web by the router heads. The vertex of each cutting angle is spaced from the respective web end to form a flat on the web between the top and bottom bevels. The cutters are mounted for rotary adjustment to vary the inclinations of the router heads, and thus of the bevels being formed. The axis of adjustment lies on a plane bisecting the cutting angle so that the top and bottom bevels will continue to converge toward the center plane of the web.
