Abstract
A slicing band consists of a base and an integral reduced cross section shank which is formed continuously throughout the length of the band. At the end of the shank is a scalloped cutting edge with inclined faces which intersect at the cutting edge of the scallops. The blade is constructed from an apparatus which utilizes two rotatable grinding wheels each with a flat annular grinding surface adapted to contact first one side of the blade and then the opposite side of the blade while the blade is yieldably retained against lateral movement and to effect material reduction to form the reduced cross section shank. The grinding wheel consists of cubic boron nitride, capable of performing material removal without burning or compromising the strength or other material requirements of the blade.
Claims8
A slicing blade comprising a band having a flexible base section and a cutting section integrally related thereto and consisting of a series of regularly constructed scallops forming a cutting edge with regularly spaced cutting peaks and intermediate cutting valleys, inclined side faces of said scallops which intersect at the cutting edge which extends continuously between successive crests and valleys, and a reduced cross section untapered shank interconnecting the inclined side faces and said base and of substantially constant cross section throughout the length of the blade and of narrower dimension than said base to provide a continuous relief for the material being sliced by said cutting edge and providing substantially frictionless movement of the blade through the material being cut.
A slicing blade comprising a flexible band having a base section, and a cutting section integrally related with said base section, said cutting section comprising a continuous series of regularly constructed scallops, each having a cutting edge with regularly spaced cutting peaks and intermediate cutting valleys, inclined side faces of said scallops which intersect to form a cutting edge extending continuously between successive crests and valleys, and a reduced cross section shank integrally connecting the inclined side faces of said scallops and said base with two shouldered portions between the base section and opposite sides of said shank, said shank being proportioned of substantially constant narrower cross section than said base throughout the length of the blade to effect substantially frictionless movement of the blade through the material being cut.
