Erhardt+Leimer web guiding
Elguider Web Guiding System
On an Elguider, the web changes direction four times, each by 90°, around a pivoting frame with two rollers. Swinging the frame about an imaginary pivot point on the infeed plane moves the web sideways – even where space is tight.

How it works
How It Works
A Frame That Pivots
Two rollers sit on a frame that swings around a pivot point on the infeed plane. As it swings, the web is carried sideways by friction, so there must always be enough tension between web and roller.
Why an Elguider
Guiding in a Small Space
Compact
Uses the web’s elasticity well, so it works in really tight spaces.
Accurate
Corrects the web before it reaches the next process.
Matched Sensor
Sensor fitted just after the positioning roller for fast response.
Sized to Suit
Built to your web width and tension.
How to choose
Planning an Installation
Path Lengths
Infeed, exit and transfer paths should each be about 60–100% of the web width.
More Tension, Longer Paths
Higher tension, stiffer material and bigger corrections need longer paths.
Sensor
Fit it behind the positioning roller, as close as possible.
