A PROCESS FOR WINDING A WEB SUBSTRATE

摘要

A process for adjusting a property of a web substrate is disclosed. The s teps include: (a) providing a nip load profile; (b) providing a calender loa d profile; (c) providing a desired first physical characteristic of the web substrate; (d) providing a desired second physical characteristic of the con volutely wound product; (e) winding the web substrate to form the convolutel y wound product; (f) measuring an actual first physical characteristic of th e web substrate; (g) comparing the actual first physical characteristic and the desired first physical characteristic; (h) adjusting the calender load p rofile according to the comparison of the actual first physical characterist ic and the desired first physical characteristic; (i) measuring an actual se cond physical characteristic of the convolutely wound product; (j) comparing the actual second physical characteristic and the desired second physical c haracteristic; and, (k) adjusting the nip load profile according to said com parison of the actual second physical characteristic and the desired second physical characteristic.
