In order to start the prevention of web breaks as early in the production process as possible, Isra Vision Parsytec has introduced the Web Break Monitoring (WBM) system, which is employed for the analysis of web breaks. By recording a video of the web with cameras distributed along both sides of the paper machine, the WBM system can quickly analyze the causes for web breaks.
The Web Break Monitoring software presents a synchronized view of all camera images to identify the problem’s cause and take immediate counter-measures enabling a fast restart of the paper machine. The image acquisition is free running and the web synchronization is realized via software in customized time periods.
Several speed signals (triggered via the rotary encoder) from different machine positions are used to determine each camera’s web position. Digital CCD matrix cameras ensure the image capturing and processing for highest image quality at full production speed.
