摘要： A tyre rasp blade (A) made with an arcuate shape having a planar body (38) with cutting teeth (34) at the outer working edge. The cutting teeth extended laterally relative to the planar body in alternating sets of curved sections. The curved sections preferably form a sinusoidal curve (36) along the outer working edge. The tyre rasp blade is made by initially forming an arcuate blade of planar material that has an outer periphery of varying radii from a center point of the arcuate blade; then cutting teeth are formed at the varying radii of the working edge of the planar material; and then an outer portion of the planar material is deformed laterally in opposite directions to form alternating, oppositely curved sections, with the cutting teeth all lying approximately at the same circumferential radius (50) so that they all contact the tyre to be buffed.
摘要翻译：本发明涉及一种轮胎锉刀刀片（A），该轮胎锉刀刀片（A）具有弓形形状，其具有在外部工作边缘处具有切齿（34）的平面本体（38）。切割齿以交替的弯曲部分组相对于平面体侧向延伸。弯曲部分优选沿着外部工作边缘形成正弦曲线（36）。轮胎锉刀刀片通过最初形成平面材料的弓形刀片而制成，该弓形刀片具有从弓形刀片的中心点起不同半径的外周边; 然后在平面材料的工作边缘的变化的半径处形成切割齿; 然后平面材料的外部在相反的方向上横向变形以形成交替的相对弯曲的部分，切削齿全部大致位于相同的圆周半径（50）处，从而它们都接触待磨光的轮胎。
