ABSTRACT:
The present invention provides a work fed truss cutter in which the work piece is a length of timber and is fed through the machine in a direction at right angles to its length. A first pair of saws at the left hand side of the work piece cut the left hand end of the work piece while a second and right hand pair of saws cut the other end of the work piece to provide bevel cuts thereon. To simplify the machine construction, of each pair of saws each saw is mounted for the pivotal movement about an axis which is physically spaced from the saw disc and at least one saw of each pair is movable linearly towards and away from the work piece which cuts in distinction to the prior art wherein of each pair of saws, the saws are pivotable about a common axis which lies as accord in relation to each saw disc, which leads to a mechanically complicated mounting arrangement for the saws.
