Is Belt Drive Safe? It looks like belt is slipping away

The belt runs on 2 pulleys. There is a sidewall on one side on the primary pulley and on the opposite side on the secondary pulley.

Since the belt slipping-off cannot happen instantaneously, opposing the sidewalls, one on each pulley takes care of this.

The pulleys do not move along their axes, hence there is no relative movement that will cause the belt to slip.
