Title: Paper web profile fault correction - uses mathematical model for current operation to eliminate residual faults on the lateral profile
Inventor: KOCH WILFRIED PROF DR
IPC: D21F7/06
Filed: 1992-11-11
Abstract: To eliminate residual faults on the lateral profile of web materials, esp. paper webs, during continuous mfg., the operation is divided into a learning and an operating phase. In the learning phase, a mathematic model is developed for the operating conditions, in a statistical process for the basic lateral profile measurements and the adjusting systems, such as the spindles at the upper lip of the stock inlet. The model is stored in a model archive, such as at a PC with a fixed panel, to hold models for the max. possible number of operating conditions. In the operating phase, the nearest model to the operation is selected from the archive for the application of a correction vector such as for the spindle setting, and used for the prodn. process. This is repeated until the lateral profile matches the model. In the operating phase, an adaption phase is repeatedly applied so that the adjustments applied according to the measured performance can be used as a learning phase, to improve the model being used. ADVANTAGE - The adjustment values during mfg. can be obtd. in a matter of mins. compared with hrs. from conventional data sources.
