Zusammenfassung:	The reversing drive is used for cine equipment in which the film spools are aligned horizontal about vertical axes. It has a friction drive roller (6') on the end of a pivoted arm (6) to swing into driver rollers (8,9) connected to the two spools. The drive roller is powered by an endless belt (5) with the direction of the belt determining which way the roller swings. The reversing drive is controlled by the direction of the belt. The other side of the belt loop is taken round a right angle and into a vertical plane. This allows simple coupling to the shutter drive.
