Apparatus for transverse cutting

A continuous motion saw for transversely severing elongated material comprising:

• a frame providing a linear path for said elongated web material,
• a conveyor for advancing said elongated web material along said path,
• a skew arm rotatably mounted on the frame for rotation about a skew axis which is skewed relative to said path,
• a planetary member rotatably mounted with respect to the skew arm for rotation relative to the skew arm about an axis which is parallel to the skew axis,
• a disc blade shaft rotatably supported by the planetary member for rotation about an axis which is parallel to said path and a disc blade mounted on the disc blade shaft for rotation therewith, the disc blade being rotatable in a plane which extends perpendicularly to said path,
• a grinder base mounted for rotation with the skew arm, the disc blade shaft being rotatably supported within the grinder base for rotation about an axis which is parallel to said path,
• a grinding stone mounted on the grinder base and positioned radially inwardly of the planetary member relative to the skew axis, and
• means connected to the planetary member for causing planetary orbital movement of the planetary member about the skew axis as the skew arm rotates,
• whereby the disc blade remains perpendicular to said path and the grinding stone remains radially inward of the planetary member as the planetary member orbits about the skew axis.
