Abstract
A cutting blade for resistance-heated elastomer cutters generally comprising a cutting edge and supporting portion joined together. The cutting edge is made of material which possesses significantly higher electrical and thermal conductivity than the material composing the supporting portion. When electrical current flows through the cutting blade, significant portion of thermal energy is generated and concentrated in the cutting edge. The cutting edge is the part of the cutting blade most directly involved in cutting of elastomer material. The generation and concentration of thermal energy in the cutting edge results in more efficient and better quality cutting and reduces heat damage done to the cutting blade and material being cut.
