Abstract
The invention is for a knife indexing apparatus for a non-rotating core cutting knife and a means for automatically indexing the knife during core cutting operations. The apparatus employs the discovery that by indexing the knife in the direction of rotation of the core, at least one additional fresh cutting edge can be presented to the work than would be the case if the knife were rotated in the direction opposite to the direction of rotation of the core to be cut.
