Abstract

See full text

A power operated knife comprises a blade supporting structure supporting an annular blade for rotation about a central axis. The blade and blade supporting structure are engagable along bearing contact locations that are spaced apart in a direction parallel to the axis so that the blade is stabilized both radially and axially as the knife operates. The blade supporting structure comprises a split blade housing member that is radially expandible and contractible to receive the blade. The split blade housing member and blade engage along relatively short lines of bearing contact that serve to minimize friction and blade heating when the knife operates. The bearing locations are spaced apart both circumferentially around the blade perimeter and in the direction of the axis so that the blade position is stabilized during operation of the knifes.
