These differ from the displacement guides in that they don't have a guide span made of two rollers. Steering web guides will typically have one guide roller installed on two raceways at an angle so the roller moves in an arc. The roller upstream from the steering roller is fixed. This arc movement provides the steering of the web.
However, even though we mention four main components, the web has to be considered a component of the web guiding system.
In our previous post on web guiding fundamentals, we mentioned the terminal web guides. These are web guides that are found at the start or the end of the process. Their location is usually on an unwind or a rewind stand. As we discussed, their installation depends on whether the guiding system is used for unwinding a roll of web or rewind a processed web into a roll.
