Causes of misalignment in carton forming

This phenomenon often occurs when using roller die cutting, because the bottom pad of the lower roller will become smaller during wear, and the linear velocity of the lower roller will become smaller. The exact solution of the size of the carton depends on the specific mechanical conditions. It is recommended to adopt Extremely wear-resistant primer pads, such as the US DICAR brand. Some machines use a variable speed motor to compensate for a bit of line speed, but this is not the ultimate solution. Using an equalizer bottom pad can solve size problems to a greater extent.
