METHOD AND SYSTEM FOR MONITORING THE PROCESS OF SEPARATION OF A WEB

A method and system for monitoring a separation process of a web in a paper machine in which the web is separated from a roll and passed into a free draw, which is preferably the first free draw of the web in the paper machine. A separation point of the web from the roll and a difference in speed of the web across the separation point, i.e., the draw difference, are measured. Cause-to-effect ratios in the separation process are established, e.g., in a data collecting system or analysis system, based on the measurements of the separation point and the speed difference. At least one additional process or running parameter of the paper machine is measured and the measurements of the separation point and the speed difference are compared with the additional process or running parameter(s) to thereby determine the manner in which the separation process of the web is affected by the additional process or running parameter(s).
