CA 2762345

The invention relates to a plate saw, comprising a workpiece support surface (20a-e) with a sawing slot (10) arranged therein, a sawing aggregate that can be displaced horizontally along the sawing slot (10) and comprises a rotatably mounted chain saw blade, the rotating axis of which being arranged below the workpiece support surface (20a-e), and further comprising at least one workpiece clamping element (80a-c) arranged on an advance carriage (60a-c) that can be displaced in the plane of the workpiece support surface. The workpiece clamping element (80a-c) comprises a mobile clamping jaw (80a-c) which in a first position is arranged below the workpiece support surface, in a second position protrudes the workpiece support surface, on which a surface (81c) is arranged such that said surface serves in the second position as first abutment surface (81c) for a workpiece that is pushed from a first direction, which is oriented parallel to the workpiece support surface, towards the clamping jaw, said clamping jaw being coupled to an actuator such that the actuator exerts a force on the clamping jaw, whereby the clamping jaw is moved from the second position into the direction of the first position, thereby clamping a workpiece in the direction of the workpiece support surface by means of a clamping surface formed on the clamping jaw.

L'invention concerne une scie à panneaux qui comprend une surface d'appui (20a-e) destinée à la pièce et à l'intérieur de laquelle un trait de scie (10) est pratiqué, un organe de sciage pouvant se déplacer horizontalement le long du trait de scie (10) et comprenant une lame de scie circulaire montée rotative, dont l'axe de rotation est placé en dessous de la surface d'appui (20a-e) pour la pièce, ainsi qu'au moins un élément de serrage de pièce (80a-c) placé sur un coulisseau d'avance (60a-c) pouvant glisser dans le plan de la surface d'appui. L'élément de serrage de pièce (80a-c) comporte un mors mobile (80a-c) qui, dans une première position, est placé en dessous de la surface d'appui pour la pièce et, dans une seconde position, s'étend au-dessus de la surface d'appui, le mors mobile comportant une surface (81c) réalisée de façon à servir de première surface de butée (81c) pour une pièce lorsque le mors se trouve dans sa seconde position, laquelle pièce est poussée contre le mors à partir d'une première direction qui est orientée parallèlement à la surface d'appui, et ce mors étant accouplé à un actionneur de sorte que l'actionneur exerce sur le mors une force qui fait passer le mors de sa seconde à sa première position, serrant ainsi une pièce en direction de la surface d'appui par l'intermédiaire d'une surface de serrage réalisée sur le mors.
