20100163663 | NEW-TYPE THIN SHREDDER BLADE HAVING BLADE POINTS WITHOUT STEPS, BLADE SETS AND MANUFACTURING METHOD THEREOF - The present invention provides a new-type thin shredder blade having blade points without steps, comprising at least one blade body and at least one cutting part that is located on the periphery of the blade body and includes a blade point, wherein the cutting part further comprises a protrusion which protrudes from the cutting part and includes a top, a inclined plane extends between the top and the blade point, and an acute angle is formed by the inclined plane and the blade body, preferably, the inclined plane is an inverted triangle, the cutting part further includes a first hemline and a second hemline extending respectively from the blade body and intersecting to the blade point, a first plane extends between the top and the first hemline and intersects with the inclined plane, the blade body includes at least one large protrusion which protrudes in the same direction as the protrusion, the blade sets formed by the above-mentioned new-type thin blades and the manufacturing method of the above-mentioned new-type thin blades are also provided, with the blade sets formed by the new-type thin shredder blade having blade points without steps of the present invention, the shredder can reduce the production cost and the energy consumption greatly, while meet the same cutting requirement of the common shredder entirely. | 07-01-2010 |
20130099040 | GROOVED INCISOR SHREDDER CUTTING BLADE SET AND METHOD - A grooved incisor blade set for paper shredders is disclosed. A blade includes a crown, a groove juxtaposed with the crown, and a center hole for a cutting arbor, where the crown and the groove define a relief channel. A stair-shaped, U-shaped or V-shaped blade assembly is described. In one embodiment, a notched grooved incisor blade having notches proximate to the central hole comes in contact with a mating grooved incisor blade also having a central hole. Force is applied to the mating blade to displace some of the body of the mating blade into the notches, affixing the blades together. A method for forming shredder cutting blades includes providing a strip of metal, forming a crown in the strip of metal, forming a relief groove juxtaposed to the crown in the strip of metal, thereby forming a relief channel, and trimming the grooved incisor blade of excess metal. | 04-25-2013 |
20130099041 | Novel paper shredder cutting blade set - A blade set for paper shredders is disclosed. In one embodiment, a notched blade having at least two notches in proximity to a central hole is brought into contact with a mating blade also having a central hole. Force is applied to the mating blade in such a fashion as to displace some of the body of the mating blade into the notches. This acts to substantially secure the blades together. In another embodiment, the notches are disposed on the edge of the blade and through the periphery. In yet another embodiment, one blade can have holes and not notches. | 04-25-2013 |
20140014755 | SYSTEM AND METHOD FOR CUTTING AND/OR SHREDDING MATERIALS - A system for shearing bulk material includes a shearing cartridge with an input port and an output port. A first plurality of rotatable blades are disposed about a first shaft, Each of the first plurality of rotatable blades includes a center aperture such that the first shaft extends through the center apertures of the first plurality of rotatable blades to selectively rotate each of the first plurality of rotatable blades simultaneously. A second plurality of rotatable blades is opposingly offset from the first plurality of rotatable blades. Each of the second plurality of rotatable blades includes a center aperture such that the second shaft extends through the center apertures of the second plurality of rotatable blades to selectively rotate each of the second plurality of rotatable blades in a direction opposite the first plurality of rotatable blades to shear and reduce the bulk material. | 01-16-2014 |
20140217222 | CAPPED SHREDDER KNIFE - A knife assembly for a shredder includes a base and a knife cap coupled to the base. The knife cap is configured to cut a material passed through the shredder. In addition, a brazing material is positioned between the base and the knife cap to secure the base and the knife cap together. The base and the knife cap have generally the same outer footprint. | 08-07-2014 |
20140231566 | CUTTING IMPLEMENT FOR FOOD PROCESSOR - In a cutting implement for a food processor, a blade axle is rotatable on a rotation axis thereof in a direction of rotation of the blade axle. At least one blade assembly is mounted on the blade axle. The at least one blade assembly has at least one single-piece arcuate blade having an upper blade section coupled to the blade axle, a lower blade section separate from the upper blade section and coupled to the blade axle, and a middle blade section extending arcuately between and interconnecting the upper and lower blade sections. The single-piece arcuate blade has a leading edge in the direction of rotation of the blade axle, with the leading edge at least in part being configured to define a cutting edge of the single-piece arcuate blade. | 08-21-2014 |
