The method consists in opening and cleaning, in the surface of a trunk to be sawn 2, a path in front of the sawblade in order to remove therefrom the foreign bodies detrimental to the blade. Means 11 to 15 connected 9, 4 to the framework 1 of the saw for trunks attack the surface of the trunk 2 in the plane of the sawblade. They advantageously comprise a circular saw 15 imparted with a rotation 10, 12 to 14 and are movable in the direction of the trunk 2 via a slide 4 connected to the movable body 5 of a pneumatic ram 5, 6. Advantageously identical means are arranged on either side of the trunk 2 in order to open and clean a path for the sawblade on either side of the trunk 2. <IMAGE>
