Rolling shears are a type of cutting tools used in metal processing for cutting thin sheets, foils or other flat materials. The shear consists of two counter-rotating rollers, which are occupied by a large number of sharp blades. When using rotary shears, the material is passed between the rollers and cut by the rotating blades. The advantage of this cutting technology is that it offers high precision and repeatability, which is especially beneficial for batch production of small parts. Rotary shears can be operated manually or automatically and are available in a variety of sizes and styles to meet the needs of different applications. They are used in many different industries, including automotive, aerospace, electronics and household appliances, to name a few.
