Henger kormányzó rendszer ELROLLER

FUNCTION 

ELROLLER steering roller systems used for web guiding already correct the web position on the infeed plane. They consist of a fixed base frame and a movable guide frame. The latter accommodates one or two positioning rollers and swivels round an imaginary pivot point on the infeed plane. A steering roller is referred to as a proportional actuator, which means that it operates under friction and must not permit slipping between the web and positioning roller. 

AREA OF USE

ELROLLER systems are always used for web guiding where there is a long entry path due to technical process reasons.

APPLICATION

Depending on the available space, steering rollers can be equipped for web guiding with one positioning roller (web is guided with a 90° wrap) or two positioning rollers (lower wrap angles possible). The following applies when mounting an ELROLLER for web guiding: The infeed path should be the equivalent of two to three times the web width, the outfeed path should be between 50 % and 100 % of the web width. The sensor should be positioned behind the positioning roller, as near to it as possible. This offers a short response time, creating improved actuating dynamics.
