ABSTRACT:
In an automated machine for cutting cloth or fabric and similar sheet materials the knife is made from a high-alloy tool steel to provide the knife with a sharp cutting edge capable under a given set of conditions to cut sheet material for a far longer period of time before requiring re-sharpening than the case with the knives previously used in such machines. A sharpener is also provided which allows the knife after becoming dull to be returned to a sharp condition while removing only a minimum amount of the knife material, thereby further increasing the service life of the knife.
