    • Provided is a roller cutter for a shredder having sufficient strength obtained by using a reduced amount of a metallic material. A roller cutter for a shredder is provided with a rotary shaft rotationally driven by a drive mechanism, finely cutting blades each including disks joined together on inside surfaces thereof, the finely cutting blades being successively mounted on and supported by the rotary shaft with the angular phase of each of the blades displaced by a predetermined angle from each other, and shaft fixation members which are fixed to the rotary shaft to thereby fix the finely cutting blades to the rotary shaft under conditions where the members have been mounted at both ends of the finely cutting blades. In this roller cutter, the finely cutting blades have folded parts forming thick-walled portions which go into contact with each other, the folded parts being formed by folding inward the sheet metal material used for forming the disks.
    • 提供了一种用于粉碎机的辊式切割机,其具有通过使用减少量的金属材料获得的足够的强度。 一种用于粉碎机的滚筒式切割机设置有由驱动机构旋转驱动的旋转轴,每个切割叶片各自包括在其内表面上连接在一起的圆盘,精细切割刀片以角度相位连续地安装在旋转轴上并由其支撑 的每个叶片彼此偏移预定角度;以及轴固定构件,其固定到旋转轴上,从而将细切割刀片固定到旋转轴上,在这些构件已经安装在精细的两端的条件下 切割刀片。 在该辊式切割机中,细切刀片具有形成彼此接触的厚壁部分的折叠部分,折叠部分通过向内折叠用于形成盘的金属板材料而形成。
