摘要： A saw blade has a plurality of teeth with each tooth formed by a beveled gullet forming a trailing face, a beveled gullet forming a leading face and a planar surface forming a curved cutting face. The gullets forming the trailing face and the leading face are beveled in opposite directions. The planar surface is generally parallel to the beveled trailing face. The unique tooth profile provides a saw tooth having a positive rake angle to significantly improve the strength of the tooth. The method of manufacturing of the unique tooth profile begins by orienting a saw blade blank about three axes and performing a first grinding operation which forms every other tooth gullet and every other planar surface. The partially formed blank is then oriented about two of the three axes in an opposite direction and a second grinding operation is performed. The second grinding operation grinds the remaining gullets and planar surfaces. The unique tooth profile of the present invention is applicable to jigsaw blades, linear edge saw blades and circular saw blades as well as the various types of bi-metal saw blades.

摘要： A saw blade (8) has a series of slots (12) spaced along one edge in each of which is secured a saw tooth (11), each slot (12) being contoured to provide an edge to support a mating surface on the tooth (11) with a further portion of the tooth extending beyond the slot (12) to overlie part of the surface of the blade (8), part (14) of the slot being sector-shaped and another part (13) including an entry portion with side edges and base edges (38) to support mating surfaces on the tooth, with the tip of the sectorshaped part (14) being located centrally of the base edge (38) and the sector-shaped part symmetrically disposed with respect to the longitudinal axis (A-A) of the slot (12). The saw teeth (11) have a pointed cutting portion (16) and a body portion contoured to provide a platform (23) located within the sector-shaped part (14) and support shoulders (38). The curved surface (20) of the sectorshaped part (23) provides a support edge supporting the blade with its support (2), although this can be provided by an attached strip (41).

摘要： The saw blade comprises tooth flanks (2) which are curved convex. The transition (3) between cutting edge (4) of the sawtooth (1) and the convex curved flank (2) is formed so that the distance (6) between the centre (2a) of the flank and the plane of symmetry of the tooth is greater than the distance (5) between the transition (3) and the plane of symmetry. The cutting edges can have a symmetrical tetragonal trapezoidal structure or an asymmetrical trigonal structure. The cutting edges can be hyperbolic or parabolic.

摘要： PCT No. PCT/CH84/00006 Sec. 371 Date Sep. 11, 1984 Sec. 102(e) Date Sep. 11, 1984 PCT Filed Jan. 12, 1984 PCT Pub. No. WO84/02676 PCT Pub. Date Jul. 19, 1984.The teeth of the saw blade (1) intended for preparing wood comprise a cutting edge (2) beginning at the tip (6) and forming an angle of intersection ( delta ) of 40 DEG -55 DEG . Adjoining the cutting edge (2) at the tooth face there is a cut-back, circular curved section (3). This curved section (3) continues at the bottom into a rounded base (4) between adjacent teeth and then continues into the edge (5) bordering the gap between the teeth, and on into the back of the next tooth. A considerably increased cutting performance is achieved with a saw blade of this kind, since a paring action is effected, and the shavings can roll away easily. Saw blades equipped with this kind of teeth can be made both as circular saw blades and also as bandsaw blades which are moved in a straight line.

摘要： A saw blade exhibits a foundation (1) of particularly spring steel, which exhibits along one edge projections (3), each separated by a chip space (2), each carrying a seat (4) each for a cutting material plate (6, 6') and each forming a tooth back (5). The cutting material plates (6, 6') exhibit a cutting edge and a true rake (7) and are arranged at an effective rake angle (.gamma.), whilst each two adjacent cutting material plates (6, 6') form a pitch (t) with the mutual interval of their cutting edges and/or cutting tips. The cutting material plates (6, 6') are attached with varying pitch (t) and with varying effective rake angle (.gamma.) .
