Relax Because the winding is not tight, when the foil is pulled out to the core direction, the foil is free to fall off into a cylindrical shape; Or when you press the aluminum foil with your fingers, there will be local depressions.
The main reason for coil loosening is that the tension is too small or uneven when cutting; Cutting speed is too fast; Pressure on the flat roller is too low.
The channel layer The surface of aluminum foil coil is irregular, resulting in the end face is not smooth.
The main reason of layer fault is blank inhomogeneity. Improper coiling tension adjustment; Improper adjustment of flat roll; The alignment system is abnormal during coiling. Or roll cutting speed is too fast.
Tower The tower deviation is caused by the cross flow layer between the aluminum surface layer and the sandwich layer, which is called the tower shape. A tower is a special case of a cross flow.
The main reasons for the tower shape are: incoming material shape is not good; Abnormal regulation system during coiling; Improper adjustment of flat roll; Improper coiling tension adjustment.
Edge warp The phenomenon of the two ends or one end of the aluminum foil roll being warped up is called warping.
The main reasons for the emergence of the navy: too many cuts, poor shape; Uneven distribution of lubricating oil; Improper adjustment of cutting edge.
