CUTTING DEVICE INCLUDING FIRST BLADE EDGE PORTION, AND SECOND BLADE EDGE PORTION IN WHICH SHEARING ANGLE AT CENTER PORTION IS LARGER THAN SHEARING ANGLE AT END PORTIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18325414 titled 'CUTTING DEVICE INCLUDING FIRST BLADE EDGE PORTION, AND SECOND BLADE EDGE PORTION IN WHICH SHEARING ANGLE AT CENTER PORTION IS LARGER THAN SHEARING ANGLE AT END PORTIONS

Simplified Explanation

The patent application describes a cutting device with a fixed blade and a movable blade.

  • The movable blade has a valley-like shape with a center portion closer to a contacting portion than the end portions.
  • The movable blade has shearing angles, with a larger angle at the center portion compared to the end portions.
  • The device includes a driving mechanism and a pressing member.
  • The design of the movable blade allows for more efficient cutting and shearing.


Original Abstract Submitted

A cutting device includes: a frame; a fixed blade including a first blade edge portion extending in an extending direction; a movable blade movable in a moving direction; a driving mechanism; and a pressing member. The movable blade includes: a second blade edge portion; and a contacting portion. The second blade edge portion has a valley-like shape such that a center portion in the extending direction thereof is closer to the contacting portion than end portions in the extending direction thereof are to the contacting portion. The second blade edge portion has shearing angles that are inclination angles relative to the extending direction. The shearing angles includes a first shearing angle that is the shearing angle at each end portion and a second shearing angle that is the shearing angle at the center portion. The second shearing angle is larger than the first shearing angle.
