Polyurethane Flat Return

The most important advantage of Flat Return rollers is their simplicity!

The rollers are made of two components: an inner stationary drum attached to a pin that allows one edge of the roller to swing forward and the other backward and vice versa, exactly in the same plane as the belt, and an outer cylinder that rotates around the inner one (see figure below). The outer cylinder tapers towards the edges, creating a slightly smaller diameter at the ends of the roller than in the middle.

When the tape slides off the center of the roll, it meets the tapered outer edges. As the belt moves over the smaller diameter part of the roller, a difference in frictional force is created which causes that part of the roller to move forward, bringing the tape back to the center.
