Offset Pivot Web Guides
An Offset Pivot Guide (OPG) is a displacement-type guide which provides web position correction with minimum entry and exit span requirements. Designed with parallel rollers, the guide pivots such that the web is twisted, thus minimizing web stress. This allows OPGs to be used in the least amount of space.
Fife OPGs are mechanical devices used to correct the lateral error in a web of material as the material runs through a process. The OPG corrects the error by displacing the web between the entry span and the exit span of the guide. The OPG consists of a fixed base and a pivoting structure with one or more rollers. The pivoting structure, referred to as a pivot carrier, rotates about a fixed or imaginary point called the pivot point. The angle of rotation is limited to ±7.5 degrees maximum. The point of rotation is ideally in the plane of the entry span or within 10% of the guide span of the entry span plane.

How much should a web guide move?
Just because a web guide doesn't move a lot does not mean that it is not performing a critical function. Learn about how much movement to expect in different winding scenarios.
