FUNCTION
The ELTRAC system ensures the exact alignment of medium and inner liner into the lamination process in the single facer. The integrated DR- Web Guider with high responsive proportional control aligns either both webs to a fixed point or one web according to the lateral position of the second web, which is not guided but detected. Fixed mounted scanning devices allow a web alignment without interruption of the web control function even during web width changes. The control system also compensates for oscillation webs during a splice. Optionally, a signal output is available for purpose of glue dam positioning. Use of high resolution scanning devices on the medium side allow an exact control of the glue dams according to the edge position of the medium web. The ELTRAC web guiding system for the single facer is fitted with an ELCORR compensating roller which automatically equalizes cross machine tension while precisely aligning the medium and liner webs. The ELTRAC system guides the liner and medium web exactly to the center line of the Single Facer. By guiding the webs to each other an optimal lamination is achieved, which allows the best possible utilization of the paper width.
