Rotary shear cutting uses two cutting surfaces typically referred to as TOP and BOTTOM blades. These rotary slitter knives spin in opposite directions allowing a sheet of material to pass smoothly through the blades, similar to a pair of scissors.
Rotary shear slitting is used to cut a wide range of materials, and similarly there are a wide range of blade designs for both the top and bottom slitter blades. The blade material varies depending on the material to be cut, cutting application, budgeting, and other factors.
