Circular knives – Upper knives
Upper knives are used often for a wide variety of applications.
Upper knives, sometimes also called disc knives, work with a lower knife or a cutting bushing. In this process the upper knife is placed on the lower knife and thus enables a type of scissors cut for very long cutting material. Upper knives are fastened to shafts. Several upper knives are attached to a shaft, and the spacing between the knives can be set via intermediate rings or a freely adjustable shaft.
These kind of systems are frequently used for lengthwise cutting of paper or foil.
