ABSTRACT:
A process for adjusting a property of a web substrate is disclosed. The steps include: (a) providing a nip load profile; (b) providing a calender load profile; (c) providing a desired first physical characteristic of the web substrate; (d) providing a desired second physical characteristic of the convolutely wound product; (e) winding the web substrate to form the convolutely wound product; (f) measuring an actual first physical characteristic of the web substrate; (g) comparing the actual first physical characteristic and the desired first physical characteristic; (h) adjusting the calender load profile according to the comparison of the actual first physical characteristic and the desired first physical characteristic; (i) measuring an actual second physical characteristic of the convolutely wound product; (j) comparing the actual second physical characteristic and the desired second physical characteristic; and, (k) adjusting the nip load profile according to said comparison of the actual second physical characteristic and the desired second physical characteristic.
