Abstract :
Rewinding process is used for storing complete products in R2R process. For some wound roll defect from slip and air entrainment is frequently generated in low tension, determining adequate operating tension is important in rewinding process. In this study, air layer thickness change according to radius ratio variance in two kinds of tension profile is analyzed. Also, minimum operating tension change according to taper value variance is analyzed. Results are shown that air layer thickness increases as radius ratio increases, and minimum operating tension for preventing slip increases as taper value increases.
