A collecting belt for the web of a spun bond or melt blown apparatus has one deflecting roller with fixed bearings and another deflecting roller with floating bearings upon which pneumatic cylinders act to provide equal forces. Upon the pneumatic system a proportional controller in response to the belt position sensor superimposes control signals to compensate for deviations in belt orientation.
