Abstract
Letters or like thin articles moving flat over a horizontal conveyor track are to be switched selectively towards either track of a fork. Such switching is controlled by intermittent pneumatically operating actuator means acting in the region of a gap in the track at the end of an incoming section, in order to deflect the articles away from their horizontal path and downwardly, these means cooperating with a physical surface which is inclined relatively to this path and towards which the articles are swung under the pneumatic action. This surface is composed of a stationary plate having a slanting operative face exposed to said pneumatically operating actuator means. The device is useful for the automatic postal sorting of letters.
