It is also one of the common problems in solvent-free compounding. Roll shifting may be caused by many factors, such as too much glue loading on the whole, or inconsistency between the two ends of the gap between the metering roll and the transfer steel roll, too large difference in the amount of glue on both sides, poor film flatness, different tightness on both sides and too small winding tension, or too small winding pressure or unbalanced pressure on both sides.
According to the specific situation, it can be solved by reducing the amount of glue, readjusting the gap between the metering roller and the transfer steel roller, replacing the base film with good flatness, adjusting the tension (and tension taper) and winding pressure.
