Abstract

The automatic web splice control system determines when an expiring roll of web reaches a preselected splice radius by sensing when the web roll has diminished to preset first and second radii. Then the system computes the roll cross-sectional area between the second radius and the preselected splice radius divided by web caliper to determine in advance the web length that will be drawn. Commencing at the second radius, the system then measures the amount of web drawn from the roll and when that amount equals the precomputed web length, the system generates a splice signal indicating that the roll has diminished to the preselected splice radius.
