Working Principle
The metal coil is first transported to the uncoiler by the loading cart. The uncoiler unrolls the coil and sends it to the straightening machine and flattening machine for straightening and flattening through the material guiding device. The processed coil enters the longitudinal shearing machine, and the blades of the longitudinal shearing machine cut the coil into multiple narrow strips according to the preset width. The waste edges generated during the cutting process are collected by the waste edge rewinder. The cut narrow strips adjust the tension through the tension mechanism and then enter the rewinder to be wound into a coil. After the winding is completed, the unloading cart unloads the coil.
