Abstract
Saw blade (1) with evolutionary tooth profile and different pitch, characterized in that said triple-bevel blade is divided into sectors (2), themselves divided into portions (3), each portion (3) having a different pitch which increases progressively from portion (3) to portion (3), the depth of the teeth also varying over several portions.

A saw blade (1) divided into successive sectors (2) corresponding to a tooth profile that is evolutionary and of different pitch, characterized in that the tooth profile of said blade is a triple bevel profile and in that each sector (2) is itself divided into portions (3), each portion (3) having a different pitch which increases progressively from one portion (3) to the next, the depth of the teeth also varying from one portion (3) to another.
The saw blade (1) as claimed in one of the preceding claims, characterized in that each sector (2) comprises from two to five portions (3).
The saw blade (1) as claimed in one of the preceding claims, characterized in that the angle of attack varies according to the pitch of the portion (3).
The saw blade (1) as claimed in one of the preceding claims, characterized in that the length of the portions (3) can vary.
The saw blade (1) as claimed in one of the preceding claims, characterized in that the variation in pitch between each portion (3) is from 1 to 3 teeth per 2.54 centimeters.
The saw blade (1) as claimed in one of the preceding claims, characterized in that the pitch varies from 1.5 to 8.5 millimeters.
The saw blade (L) as claimed in one of the preceding claims, characterized in that the cutting angle ranges between 25 and 35°.
The saw blade (1) as claimed in one of the preceding claims, characterized in that it consists of a single sector (1).
The saw blade (1) as claimed in one of the preceding claims, characterized in that it has a crosscut tooth profile.
The saw blade as claimed in one of the preceding claims, characterized in that the length of a sector (2) is 50 millimeters.
