摘要

Device for grinding a moving knife (24) for cutting tobacco (16) comprises a cutting edge running along a first path (44), and a moving grinding body (40). The grinding body is arranged and moves so that during its grinding interaction with the knife section the first path cuts a second path (46) at an angle corresponding to a desired free angle. An Independent claim is also included for a process for grinding a moving knife for cutting tobacco. Preferred Features: The grinding body is formed as a rotating segment or roller. The knife moves with its cutting edge in an opposing direction (B) to the grinding body. The first path overlaps or penetrates the second path in sections. The knife is arranged on a rotating support (28) so that the first path follows a circle.
