What options do I have for belt tracking?

Carey Bienert -

Active Tracking Mechanism- This system consists of an edge sensor and a steering roll(s) that is adjusted by an automatic system that has an actuator, such as a hydraulic cylinder, air cylinder or electric motor. When the edge sensor detects a belt movement (cross machine direction) the steering roll is adjusted to bring the belt back to the center of the machine. This method is recommended for larger belts with a width of three or more feet.

Continuous Edge Guide- Belts up to approximately three feet wide can be guided by attaching an extruded silicone guide, Kevlar rope or rubber V-belt to the inside of the belt.

The machine must have grooved rollers (and sometimes a grooved slider bed) for the guide to engage in.

Buttons, Dots, Snaps, ETC- This method is similar to the continuous edge guide. Tracking is accomplished by attaching a series of metallic dots or snaps to one edge of the belt. These small devices are placed an inch or two apart.

As with the continuous edge guide, the machine must have a groove machined in some of the rollers. The pins run in the groove.
