Knowing the exact speed of forming fabrics is important in many ways:
- sheet formation and strength properties are affected by the jet-to-wire ratio
- unknowingly dragging or rushing the fibers can be hard to determine
- when the top and bottom fabric run at slightly different speeds on twin wire machines, the sheet gets rubbed. On coated paper grades this causes the ‘orange peel’ effect
