The shredder blade is suitable for chopping the material fed into the slot of the chopper head. The shredder blade includes a shredder blade body, which generally defines a plane and has a relative main surface. The main body of the shredder blade is provided with a central hole through which the central hole is suitable for half the diameter of the shredder blade. At least one cutting flange is located on one of the relative main surfaces of the shredder blade body and extends outward from there at an angle to the plane. The at least one cutting flange forms a second cutting mechanism, and the second cutting mechanism is adapted to rotate through a path of the second approximate circle, which is located at a roughly second radius from the center of the chopping blade body. The second radius is smaller than the first radius such that the cutter blade is suitable for longitudinal cutting in the material, and at least one transverse cutting is also performed in the material at least partially. The invention relates to a shredder blade in general, and more specifically to a shredder blade capable of cutting materials using two different cutting mechanisms.

A conventional shredder blade has a cutting mechanism along the periphery, such as a sharp circumferential edge, a serrated edge or two or more cutting teeth with serrated edges between them. All of these shredder blades work by tearing the material into strips. Although this method of tearing is considered satisfactory, it is sometimes better to shred the material further rather than just cutting the material into strips. One solution that has been developed is to crosscut the material so that it can be cut into very short pieces. This makes it more difficult to reassemble the shredded document, thus increasing the security of the shredded document. Although various techniques have been developed to cut the material into smaller pieces, the technology tends to be expensive to manufacture. It is advantageous to provide a shredder blade suitable for cross cutting material fed into the chopper. It can be easily manufactured; and it is better to use two different cutting mechanisms to cut the material.

A shredder with a plurality of shredder blades, the shredder blades are suitable for chopping the material fed into the shredder, including a plurality of shredder blades arranged in the shredder and suitable for chopping the materials inserted into the shredder, each shredder blade includes: a shredder blade body, which is usually limited to a plane and has a relative main surface; a shredder blade main body is arranged in the shredder and is suitable for cutting materials inserted into the shredder The body has a central hole through which the center hole is adapted to install the shredder blade body on the chopper shaft, the shredder blade body has an outer circumference, and at least a part of the outer circumference forms a first cutting mechanism, the first cutting mechanism is adapted to rotate through a circumferential path generally located at the first radius measured from the center of the chopped blade body; and at least one The at least one cutting flange forms a second cutting mechanism, which is adapted to rotate through a path located at a second large circular shape, usually at a second radius from the center of the cutter blade body, and is adapted to extend outward from the cutting flange body at an angle from the plane The material is cut when the material is outside the main surface of the cutter blade body, where the second radius is less than the first radius such that the chopper blade is suitable for longitudinal cutting in the material and at least partially performs at least one transverse cutting in the material; and wherein, most of the plurality of the cutting blades have at least one main surface, which is not cut with adjacent provided chips The main surface of the blade contacts.
