Device for a rotary saw blade (1) for reducing the sound level during sawing and for reducing the risk of accidents due to an improved quick stop function. On both sides of a non-sawing portion of the saw blade (1) are arranged at least one against the side place of the saw blade (1) contactable member (4, 4'), arranged to facilitate a movement in direction from/towards the saw blade (1). Said members (4, 4') are arranged with channels which are open towards the side plane of the saw blade (1), and are pressed by a pressure acting means (6, 6') in direction towards the saw blade (1). Prior to start of the rotary movement for the saw blade (1), a pneumatic and/or hydraulic medium under pressure is supplied to said channels to form a pneumatic and/or hydraulic cushion between the saw blade (1) and thereagainst contactable members (4, 4'), thereby moving same from their contact position to a separated but adjacent position to the saw blade (1) with a sound and oscillating damping pneumatic and/or hydraulic pressure influence exerted on the saw blade (1).

L'invention concerne un dispositif pour lame de scie circulaire (1) qui permet de réduire le niveau sonore à l'utilisation et, par ailleurs, le risque d'accident grâce à un système d'arrêt instantané amélioré. Des deux côtés d'une partie non sollicitée pour le sciage sur la lame (1) se trouve au moins un élément pouvant être en contact (4, 4') avec le côté de la lame (1), conçu pour faciliter un mouvement depuis/vers la lame (1). Chaque pièce (4, 4') a des canaux qui s'ouvrent sur le côté de la lame (1) et sont poussés en direction de la lame par un système à pression (6, 6'). Avant d'enclencher le mouvement circulaire de la lame (1), un milieu pneumatique et/ou hydraulique sous pression est envoyé dans lesdits canaux ouverts de sorte qu'un coussin d'amortissement pneumatique et/ou hydraulique soit formé entre ladite lame (1) et les pièces (4, 4') venant en contact avec elle, ce qui permet aux pièces en question de passer d'une position de contact à une position distante mais adjacente à la lame (1), laquelle subit une pression hydraulique et/ou pneumatique d'amortissement des oscillations et du bruit.
