    Abstract: The present invention provides a composite blade module and cutting means using the same. The composite blade module comprises a blade and at least one elastic layer. The elastic layers are adhered to a part of cutting edge and/or a back of the blade selectively. The composite blade module is used by the cutting means to cut an object to be cut. The elastic layers may be used as a shock absorber to absorb the collision force acting on the blade, thus reducing the probability of breaking blade, during the cutting process. Furthermore, if the blade is broken unfortunately, the broken blade is still adhered to the elastic layers, in such a way that the broken blade is prevented from either being drawn into the cutting means and then damaging the means, or being ejected and then endangering the operator, leading to safety guarantee during cutting.

  • Patent number: 5167177
    Abstract: An apparatus for slicing objects, such as potatoes, with a rotatably mounted knife assembly. Objects (such as potatoes) to be sliced are conveyed downward toward the knife assembly between a gripper chain and a feed chain. A pair of springs provide a biasing force which urges the chains together, thereby ensuring that the conveyed potatoes are fed positively and uniformly toward the knife assembly. Preferably, two feed rolls having teeth are mounted between the lower ends of the chains and the knife assembly (each feed roll at the end of a rotating, slidable shaft). The teeth of the rotating feed rolls grip each potato conveyed against them by the chains, and force each such potato downward against the rotating knife assembly. Preferably, a support and retaining plate is fixedly mounted to the feed mechanism to constrain vertical movement of the feed rolls as they rotate with a potato gripped between them.

  • Patent number: 4369680
    Abstract: A rotary slicing tool for a food processor has a horizontal disc-like member with an opening therein and a cutting blade positioned at an elevated location above the opening relative to the horizontal top surface of the disc-like member providing a cut having a thickness determined by the vertical elevation between the cutting blade and the horizontal top surface. A removable cover disc having the same general configuration and proportion as the disc-like member is mounted on the cutting member for changing the thickness of the slices as determined by the thickness of the cover disc. The cut of the rotary slicing tool may therefore be varied by using removable and replaceable cover discs of different thicknesses without necessitating the complete removal and replacement of the rotary tool in the food processor. Certain cover discs may include auxiliary blades for converting the slicing tool into a French fry slicer or Julienne slicer.
