If the width of the sleeve is larger than the width of the steel sheet, the sleeve protrudes from winding and packaging. When the width of the supplied sleeve is smaller than the width of the steel sheet, a defect in the shape of generating a wave in the inner edges of the edges due to tension when the steel sheet is wound early in the coil form occurs.

In case of defects such as winding or shape defects as described above, the value as a finished product is lost and defects in the manufacturing cost and productivity decrease are caused by defect sorting and rewinding in the reprocessing line (RCL). do.

In addition, the risk of safety accidents were great because the manual work is performed on the sleeve of the weight, there is a problem of reduced production due to excessive work time.
