Rotary shear slitting is the industrial equivalent to the cutting process used by a pair of scissors. In rotary shear slitting there are two cutting surfaces typically referred to as the TOP and BOTTOM blades. These rotary slitter knives spin in opposite directions allowing a sheet of material to pass smoothly through the blades.
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. Carolina Knife supplies a wide range of rotary cutting blade designs in all popular materials.
