Patent ID: 7584013

Claim:
A computer program stored on tangible computer readable media for causing one or more operations for recovering cross-direction (CD) caliper control performance during startup of a sheet making machine after an occurrence of a sheet break to be selectably performed, said sheet making machine having feedback CD control, said computer program comprising: computer usable program code configured to allow the selection of one or more of said recovering CD caliper control operations to be performed during startup of said sheet making machine after said sheet break, said selectable operations selected from a group consisting of: a conditioning of a calender stack mounted on said sheet making machine with said feedback CD control in a suspend state using setpoints corresponding to a heating gradient of said calender stack prior to said sheet break and a conditioning with said feedback CD control in a suspend state of a measurement from a sensor for measuring caliper of a sheet being made by said sheet making machine; and computer usable program code configured to perform said selected operations in a predetermined order during startup of said sheet making machine after said sheet break.
