LOW-COST RING BLADE FOR ROTARY KNIVES

摘要

A ring blade (18) for use with a rotary knife (10) includes a first member that forms an annular blade member (90) having an annular cutting edge (96) for cutting into material with which it is brought into contact. A second member (92) is fixed to the annular blade member to provide a drive surface by which the ring blade is rotated. In one embodiment the blade member is machined. In another embodiment the blade member is cold formed from a thin sheet of hardenable steel.
