The Operating Process of Slitting machine

A slitter machine, a product of the converting industry, is designed to convert material for various end-user purposes. For example, material such as a giant master roll paper is converted into such end-user products as credit card receipts and cash register rolls. Individuals who desire to operate a slitter machine must have at least a basic knowledge of the technology and follow a carefully designed strategy for operating the mechanism.

And the operation process of slitter rewinder can be divided into two kinds: for soft materials and for hard materials. Several methods are available for soft materials like plastic films and paper. Razor blades, straight, or circular blades are being used. Some blades cut through the material while others crush the material against a hard roll. Those are similar to knives and cut the material into narrow strips, which are called coils when being rewound. The cutting blades can be set to a desired width. Some machines have many blades to increase the options of cutting widths, others have just a single blade and can be set to a desired location. The slit material is being rewound on paper or plastic cores on the exit side of the machine.

On the other hand, for harder materials, such as sheet metal, blades cannot be used. Instead a modified form of shearing is used. Two cylindrical rolls with matching ribs and grooves are used to cut a large roll into multiple narrower rolls. This continuous production process is very economical yet precise; usually more precise than most other cutting processes. However, the occurrence of rough or irregular edges known as burrs are commonplace on slit edges. Also, the geometry of these rolls is determined by specific tolerances in addition to the type of material and workpiece thickness.
