<p>The sawtooth has a roof edge (1) that runs perpendicular to the direction of motion of the sawtooth., where the sawtooth has a trapezoidal cross section. Two mirror symmetrical cutting flanks (3, 4) run diagonally outwards to a mid-plane (2) of the sawtooth from ends of the edge. Cutting shoulders (5, 6) are connected to the respective flanks parallel to the edge, where the shoulders run outwards upto side flanks (7, 8). Front flanks (9, 10) are provided between the cutting flanks and the shoulders, where height of outer ends of the cutting flanks is greater than the height of the shoulders.</p> |
