Concave Conveyor Pulley Centering

The pitch line of the belt leaves pulley A at point a. In order to contain this point the center plane of pulley B would have to coincide with XX. Similarly, the belt is delivered from b on the under side of pulley B, into the plane Y 1 Y. The result of this action is that the belt works toward the left and tends to leave the pulleys.

The former is far more common, and the latter not appropriate for timing and standard V-belts unless there is a twist between each pulley so that the pulleys only contact the same belt surface. Nonparallel shafts can be connected if the belt's center line is aligned with the center plane of the pulley.
