Slicing cutter blade

A slicing cutter blade, adapted for securing to a holder means having a tension ring provided with a protuberance thereon, comprising an annular sheet steel body having a central opening therein, said annular body being rolled in a predetermined direction and including:

• a cutting edge formed at the inner circumferential edge of the central opening in said annular body;
• an outer circumferential portion secured to said holder means;
• a tension generating section adjacent said outer circumferential portion, said tension generating section being forced into contact with the protuberance on the tension ring of said holder means;
• and
• a middle portion located between said cutting edge and said tension generating section, said middle portion having a plurality of circumferentially arranged and equidistantly spaced circular apertures disposed thereon for generating increased circumferential stress in said cutting edge, a first group of circular apertures being located on a first line parallel to said predetermined direction which passes through the center of the central opening in said annular body, said first group of circular apertures having a first diameter;
• a second group of circular apertures being located on a second line perpendicular to said first line which passes through the center of said central opening, said second group of circular apertures having a second diameter which is less than said first diameter;
• and a third group of circular apertures located intermediate said first and second lines having diameters greater than the diameter of the apertures on said second line, the diameters of said intermediately located apertures increasing as their distance from said second line increases.
