| Summary: | This invention relates to a continuous motion orbital saw for transversely severing elongated multi-ply web material into shorter length products. More particularly, the invention relates to an orbital saw in which the cutting blade is mounted on a skew arm which rotates about an axis which is skewed relative to the path along which the elongated product is advanced. Compensation for the skew angle is accomplished by orbiting the blade in a planetary fashion so that the blade remains perpendicular to the path throughout the orbit. Grinding stones for sharpening the blade are positioned radially inwardly of the blade throughout the entire orbit.
The cutting blade of a continuous motion saw is mounted on a skew arm which rotates about an axis which is skewed relative to the path along which the product to be cut is advanced. The blade rotates about an axis which is parallel to the path. The blade orbits in a planetary manner to compensate for the skew angle and to ensure that the blade remains perpendicular to the path. Grinding stones for the blade are mounted radially inwardly of the blade throughout the entire orbit of the blade. |
