Slitting machine manufacturers have learned that there are several slitting methods that can be used for soft materials, such as plastic films and paper. Blades, straight or round blades are being used; some blades cut the material, while others press the material against the hard roller. These knives are similar to knives, cutting the material into narrow strips, which can be called coils when they are rewound.
        The cutting blade can be set to the desired width. Some machines have many blades to increase the choice of cutting width, other machines have only one blade, and can be set to the desired position. The cut material is unwound on paper, plastic or metal core on the exit side of the machine.
        This process of slitting machine is applied because of its low cost and high mass production accuracy. Some machines have a program that monitors the blade and often grinds the blade to maintain the quality and accuracy of the cut; depending on the industry and the product being cut, these The machine can run between 10 m / min (special metal mesh) and 5000 m / min (paper making process).

         These machines can also contain a large number of automated functions to accurately control the tension of the material, automatically position the cutting knife, automatically align the core of the wound material, and reduce the manual operation of the coil; examples of materials that can be cut in this way are: tape, Foam, rubber, paper products, foil, plastic (such as tarps and plastic wrap), glass cloth, fabrics, release lines and films.
