Abstract

The invention relates to a blade, more particularly for a meat grinder. The blade (10) has a collar-type sealing ring (18) between the hub (11) and the inner ends of the blade wings (14). The sealing ring (18) has the same height as the hub (11) as the adjacent sealing ring (18) has or the hub (11) has a smaller height. The hub (11) thus does not impede the rubbing of the cutting edges (16, 17) of the blade (10) or the rubbing of the sealing ring (18).
