<p>A sawing apparatus for sawing long lengths of material into shorter pieces having a predetermined length and discarding spoiled and short end pieces comprises a saw movable across a saw table formed in two parts which can be tilted independently of each other to tip sawn material into a receptacle. The downstream part has a nose piece projecting just beyond the saw to support the leading end of a length to be sawn. The apparatus also comprises exit and entry tables and a number of sensors for respectively detecting the leading and trailing ends of the lengths of material and for automatically initiating sequences of operations of releasable clamps for clamping the lengths of material, traversing movements of the saw, and the tiltable table parts.</p> |
