FUNCTION With the ELTWIN cloth guiding systems, the web edge is scanned either mechanically by a sensor lever or without contact using optoelectronics. The sensor signal controls a diaphragm cylinder or a lifting magnet that presses the control roller against the counterpressure roller. The web edge is controlled by roller offset and contact pressure of…
FUNCTION Guiding slats arranged around the circumference form the basis of the web guiding. In the basic version, the guiding slats are fixed to a guide plate so that they can be adjusted to the side via an actuating drive. In the case of segmented guiding slats, both guide plates are connected with a push…
FUNCTION A roller arrangement comprising two or three web guiding rollers pivots around an imaginary pivoting point in the infeed plane immediately in front of the actuator. Immediate corrections are made via the lateral movement. The additional skewed positioning provides continuous correction of the running web. Here, there must be traction between the web and…
FUNCTION The E+L Split Web Guiding concept was developed to take advantage of the cost savings using the low cost end rolls in the corrugating process. The end rolls are usually recycled in the paper plant, because they are undersized for standard width production. The concept of Split Web utilizes these undersized rolls as medium,…
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…
FUNCTION The CorrAligner is a fully automatic web guiding system for the corrugator bridge, installed before the web tension system and the preheater. Due to the geometrical frame construction, it operates as stabilisation, unlooping and web guiding device. According to experience the use of mechanical edge guides causes damage of the web edges and web…
