Patent ID: 8584567

Claim:
A saw blade for a machine operating with adjacent saw teeth traveling in two opposite and parallel directions, the saw blade comprising a blade substrate, teeth, and tooth necks formed at the periphery of the substrate for holding the teeth in place, the saw blade having a surface intended for sliding against a contact area associated with an adjacent saw blade, wherein said surface is located adjacent to the tooth necks and that each tooth neck has a protection surface, which is located in a plane that is parallel to the plane of the blade substrate, for protecting the tooth against impact with any part of said adjacent saw blade, each tooth being located on the respective neck in such a way that the tooth is displaced from the protection surface and from the adjacent saw blade in a direction normal to the plane of the protection surface, wherein a contact zone located at the periphery of the blade substrate and said protection surfaces are located in substantially the same plane, which is parallel to the plane of the blade substrate, the contact zone and the protection surfaces thus all being able to slide against said contact area, and wherein the tooth has an adjacent surface being substantially parallel to the plane of the protection surface, the distance between the adjacent surface and the protection surface being 0.005 to 0.10 mm.
