How are soft materials processed? Let's take a look with the slitting machine manufacturers.
        There are several methods for cutting soft materials, such as plastic film and paper, which can be achieved by using blades, straight or round blades, while others will be cut The material is pressed against the hard roller.
        Those cutting materials similar to narrow strips can be called coils when they are rewound, and 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 is applied because of its low cost and high precision in mass production. Some machines have a program that monitors the blade and often grinds the blade to maintain the cutting quality and accuracy. Depending on the industry and the product being cut, these machines can operate 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 winding core of the winding material, and reduce the manual operation of the coil.

         After reading the above, I believe everyone already knows the processing principle of soft materials.
