Abstract

A saw blade for cutting of wood, comprising cutting teeth which have filed or sharpened front and rear lateral edges, said edges meeting at a sharp point alternately on the right and the left side of the saw blade, where the cutting teeth are arranged in recurrent main groups of eight cutting teeth, each main group being divided into two subgroups comprising four cutting teeth each. Each subgroup comprises one cutting tooth set to a first side, two cutting teeth set to a second side opposite said first side, and one unset cutting tooth located between the two last-mentioned cutting teeth, and the set cutting teeth in each subgroup are set respectively to that side where the sharp point is located.

1-8. -8. (canceled)

9. A saw blade for cutting of wood, comprising cutting teeth which have filed or sharpened front and rear lateral edges, said edges meeting at a sharp point alternately on the right and the left side of the saw blade, wherein the cutting teeth are arranged in recurrent main groups of eight cutting teeth, each main group being divided into two subgroups comprising four cutting teeth each, that each subgroup comprises one cutting tooth set to a first side, two cutting teeth set to a second side opposite said first side, and one unset cutting tooth located between the two last-mentioned cutting teeth, and that the set cutting teeth in each subgroup are set respectively to that side where the sharp point is located.

10. A saw blade according to claim 9 wherein the distances between the adjacent subgroups are larger than the distances between the cutting teeth within the subgroups.

11. A saw blade according to claim 10, wherein the fourth cutting tooth in the first subgroup is set to one of said first and second sides, and the first cutting tooth in the second subgroup of the same main group is set to the opposite side.

12. A saw blade according to claim 10 wherein at least one unset scraping tooth is arranged between two adjacent subgroups and between two adjacent main groups.

13. A saw blade according to claim 9, wherein at least one unset scraping tooth is arranged between two adjacent subgroups and between two adjacent main groups.

14. A saw blade according to claim 13, wherein the scraping tooth comprises two points angled away from each other.

15. A saw blade according to claim 14, wherein the sharp points of the cutting teeth extend above the heights of the scraping teeth.

16. A saw blade according to claim 15, wherein the respective distances between a scraping tooth and each adjacent subgroup are larger than the distances between the cutting teeth within the subgroups.

17. A saw blade according to claim 13, wherein the sharp points of the cutting teeth extend above the heights of the scraping teeth.

18. A saw blade according to claim 17, wherein the respective distances between a scraping tooth and each adjacent subgroup are larger than the distances between the cutting teeth within the subgroups.

19. A saw blade according to claim 14, wherein the respective distances between a scraping tooth and each adjacent subgroup are larger than the distances between the cutting teeth within the subgroups.

20. A saw blade according to claim 9 wherein two cutting teeth in the first subgroup are set to one of said first and second sides, and two cutting teeth in the second subgroup of the same main group are set to the opposite side.

21. A saw blade according to claim 20 wherein the distances between adjacent subgroups are larger than the distances between the cutting teeth within the subgroups.

22. A saw blade according to claim 21 wherein at least one unset scraping tooth is arranged between two adjacent subgroups and between two adjacent main groups.

23. A saw blade according to claim 20 wherein at least one unset scraping tooth is arranged between two adjacent subgroups and between two adjacent main groups.

24. A saw blade according to claim 23 wherein the scraping tooth comprises two points angled away from each other.

25. A saw blade according to claim 23 wherein the sharp points of the cutting teeth extend above the heights of the scraping teeth.

26. A saw blade according to claim 9, wherein the fourth cutting tooth in the first subgroup is set to one of said first and second sides, and the first cutting tooth in the second subgroup of the same main group is set to the opposite side.

27. A saw blade according to claim 26, wherein at least one unset scraping tooth is arranged between two adjacent subgroups and between two adjacent main groups.

28. A saw blade according to claim 27 wherein the scraping tooth comprises two points angled away from each other.

29. A saw blade according to claim 27 wherein the sharp points of the cutting teeth extend above the heights of the scraping teeth.

30. A saw blade according to claim 26, wherein at least one unset scraping tooth is arranged between two adjacent subgroups and between two adjacent main groups.

31. A saw blade according to claim 30 wherein the sharp points of the cutting teeth extend above the heights of the scraping teeth.
