ABB Automatic Braking System offers you a powerful means to speed up the correction of web defects and maintain maximum re-reeler/winder efficiency - for improved overall productivity.
The Automatic Braking System (ABS) supplies the advanced tool required for efficiently locating and correcting defects. It increases winder or re-reeler capacity by optimizing the time to locate the defects to be patched or culled. When manual control is used, the unwinding rate must be reduced to crawl speed well in advance of suspected problem areas in order to avoid missing the defect. This often leads to the winder/re-reeler function becoming a bottle-neck in the paper production line.
Automatic Braking can be effectively utilized in virtually any paper type or grade.
By taking into consideration both the location of the defect and the limitations of the customer specific winder drive, Automatic Braking calculates the optimal speed curve to the defect. It then automatically slows down the drive to crawl speed or alternately stops the winder or re-reeler at the precise selected defect location. The status of the unwinding, e.g. the length to the next stopping position, is continuously updated on the display. With Automatic Braking, the operators have the additional facility of virtually unwinding the reel in advance. With the help of the defect classification and high resolution images, operators are able to easily determine the severity of the defects and thus minimize unnecessary stops.
Easy to use
The system is operated through the PC operator station installed at the winder or re-reeler. When a reel is transferred for unwinding the operator selects the specific reel data from the Web Imaging database. The defects for automatic braking can be freely selected individually or globally by defect category. The selected defects are prominently marked on the video display for easy operator recognition.
