The cutting-die unit „DIN ISO 34-1 trouser“ consists of a cutting blade and spring-loaded down holders. The cutting- & nick-blade is made of powder-metallurgic knife steel and thereby guarantees an extreme lifetime.
Testing the tear resistance requires an exact nick at a defined point on the specimen. The punching knife is equipped with a replaceable nick blade for this purpose.
The blades are transversally sharpened on both sides, which results in vertical cut lines of an exact specimen cross section.
