Abstract:
1. A method comprising the steps of: providing a paperboard handling machine comprising a frame and a roll support assembly having left and right roll support arm assemblies which are movably mounted on the frame; mounting a first paperboard roll having left and right ends on the roll support assembly between the left and right arm assemblies; while the first paperboard roll is mounted on the left and right arm assemblies, measuring with a first distance sensor a first axial distance from a first reference point which is axially fixed relative to the frame to a second reference point on the left arm assembly; while the first paperboard roll is mounted left and right arm assemblies, measuring with a second distance sensor a second axial distance from a third reference point on the left arm assembly to the left end of the roll; calculating with a logic circuit a first axial position of the roll based on the first axial distance; wherein the step of calculating the first axial position is based on the second axial distance; comparing the calculated first axial position with a predetermined correct axial position; and if the first and correct axial positions are different from one another, adjusting the roll axially while mounted on the roll support assembly to move the roll from the first axial position to the correct axial position.
