Cutting blade

摘要

A cutting blade includes a first and a second elongated frame part, and projections protruding from the first and the second elongated frame part in the cross direction. The first and the second frame part are attached to each other by blades, the blades being individually attached to the first frame part at first pivot points and to the second frame part at second pivot points so that the opposite ends of the blades protrude from the first and second pivot points, respectively, in the cross direction of the frame parts. The first and the second elongated frame part are movable relative to each other to rotate the blades around the first and second pivot points and to generate a cutting movement between each end of the blade and projection approaching each other.

1. A cutting blade assembly, comprising:
a first and a second elongated frame part; and projections protruding from the first and the second elongated frame part in the cross direction, wherein the first and the second frame part are attached to each other by blades having a first end and a second end, the first end and the second end of the blades are sharpened, the blades being individually attached to the first frame part at first pivot points and to the second frame part at second pivot points in such a way that opposite first and second sharpened ends of a single blade protrude from the first and second pivot points, respectively, in the cross direction of the frame parts; and the first and the second elongated frame parts are movable relative to each other to rotate the blades around the first and second pivot points and to provide cutting between the first sharpened ends of the blades and projections of the first elongated frame part approaching each other and to provide cutting between the second sharpened ends of the blades and projections of the second elongated frame part approaching each other.
