Sheet metal straightening machines are machines used for straightening sheet metal. When sheet metal is manufactured, it can be uneven due to manufacturing tolerances or damage. To eliminate these inaccuracies and bring the sheet into a flat, smooth shape, it is passed through a sheet metal straightening machine. A plate leveler typically consists of several pairs of rolls that pass through the plate. The rolls are arranged to smooth the sheet evenly and correct any deformations. Depending on the machine configuration, sheet metal levelers can be designed for different thicknesses and sizes of sheet metal. Sheet metal levelers are usually used in the metalworking industry, especially in the production of car body parts, machines and other sheet metal structures.
