This uncoiling and leveling production line has a stoppage; why have this? 

In some production lines, a controlled stoppage is intentionally built. This planned halt is used to achieve objectives such as ensuring proper alignment, calibration, and quality control before moving on to subsequent processing steps. It can also allow for critical adjustments or maintenance checks without compromising the final product quality.

In English, you might refer to this as a "planned production line stoppage" or "controlled production halt."

Performance Features:

◆ This production line is a specialized system designed to flatten thin metal coils and shear them into plate blocks. It typically consists of a feeding trolley, uncoiler, plate support and tensioning device, main leveling unit, movable bridge, guiding and correction device, length measurement mechanism, lamination device, shearing machine, conveying worktable, pneumatic discharge rack, hydraulic lifting and stacking table, material transporting roller table, as well as a hydraulic system and an electrical control system. All components work in unison under PLC control, and key hydraulic, pneumatic, electrical control elements, and the length measurement system are selected from renowned brands.

◆ The equipment is primarily used for processing cold-rolled carbon steel coils, stainless steel coils, and non-ferrous metal coils. By employing a six-stage leveling machine, it is capable of flattening and length-shearing coils made from metals like aluminum, which require high surface quality.

◆ According to customer requirements, the leveling process can be executed using either a two-stage (primary and fine) leveling system; length feeding and shearing may utilize either conventional electromechanical coordination, digital variable frequency technology, or AC servo technology; and the shearing machine can be configured as a conventional mechanical type, a hydraulic type, a high-speed guillotine-type powered by hydraulic motors or pneumatic clutches, a mobile tracking cutter, or a rotary flying shear. Additionally, with compatible forming machines, the system’s functionality can be further extended.
