摘要： A rasp for the scraping of worn rubber tires has a generally cylindrical body composed of a multiplicity of blades peripherally adjoining one another, the blades being sandwiched between a pair of end disks held together by an axial bolt and bridged by axially extending rods which traverse at least two mounting holes in each blade. The blades may have a polygonal shape, with three or more toothed sides, overlapping one another so that one toothed side of each blade comes to lie along the periphery of the body to define part of a cutting surface. Additional apertures in the blades serve for the circulation of air therethrough, these apertures being flanked by lugs integral with the blades which are bent out laterally to form spacers therebetween; the end disks may also be apertured to facilitate air cooling of the body. Each blade tooth is bounded by four concave arcuate edges defining three sharp points, the middle point projecting radialy beyond the two flanking points; each tooth, or each pair of adjacent teeth, is symmetrical about a radial line.

摘要翻译： 用于刮擦磨损的橡胶轮胎的锉刀具有大致圆柱形的主体，其由彼此外围邻接的多个刀片组成，所述刀片夹在一对端盘之间，所述一对端盘通过轴向螺栓保持在一起，并通过轴向延伸的杆桥接， 每个叶片中至少有两个安装孔。 叶片可以具有多边形形状，具有三个或更多个齿形边，彼此重叠，使得每个叶片的一个齿形边缘沿着主体的周边设置以限定切割表面的一部分。 叶片中的另外的孔用于使空气循环通过，这些孔的侧面是与叶片成一体的凸耳，它们横向弯曲形成间隔件; 端盘也可以是开孔的，以便于机体的空气冷却。 每个叶片齿由限定三个尖锐点的四个凹弧形边界限定，中点突出超出两个侧面点; 每个齿或每对相邻的齿相对于径向线对称。
