When you work in the papermaking industry, you become familiar with some of the machines that help make paper. However, there are also several machines that roll and cut paper too. One type of machine, a slitter, is responsible for cutting paper to various sizes. While you might know that, what you might not know is that there are three kinds of slitters, and if you have only seen and worked with one kind, you may want to try the other two, or at least see these machines in action. Here are the descriptions and operational features of the three kinds of slitters and why you might want to add additional kinds of slitters to your industry.
Duplex Wind Slitters
Duplex wind slitters are so named for their twin roll spinners. Two rolls of any type paper or tape product are wound or rewound on the twin rollers. As these rollers spin, the material is sliced and transferred to another roll or you can transfer material between the twin rollers as it is being cut. You may want to add a duplex wind slitter if your factory is tight on space and/or you want to increase productivity, speed and manufacturing efficiency.
Surface Wind Slitters
Surface wind slitters are responsible for winding humongous rolls of foil, paper, tape, etc. The roller is positioned in the very center of the machine and is fully supported on both ends by the frame of the machine. It is used to cut wider rolls of material, such as four-inch wide packing tape rolls. When you have customers and clients that request large, bulky and/or wide-width rolled products, you should have a surface wind slitter in house to accomplish the job.
Center Wind Slitters
Center wind slitters can be either surface wind or duplex wind slitters too. Center wind simply means that these machines cut and wind material simultaneously, but the cuts often occur in the middle of the roll, which leaves extra material on both ends. The extra material on the ends may still be used by the customer/client, especially if it matches the dimensional parameters of the products the client/customer intends to produce and sell. The extra material on the ends may also be recycled to create fresh rolls of product over and over again, a practice that many factories like yours participate in in order to cut costs and save on materials (not to mention saving trees).
