Timing belts usually run in sheaves (V-belt grooves) rather than on crowns. The flanges around the sheaves maintain alignment. Note that sometimes only one pulley will have these flanges, and the others are wide enough to work where the guided one leads. The drive belts on this year's KOP drive are a good example.
Here's a better example showing one flanged pulley and one unflanged pulley.
