Abstract
An envelope inverter comprises a conveyor (14) arranged below a surface (2) onto which envelopes (6) are delivered through a slot (4). The surface (2) is arranged such that each envelope (6) is unstable thereon, and tends to rotate about the edge (12) of the surface, striking the conveyor (14), which moves in a direction tending to continue the rotating movement until the envelope (6) comes to rest inverted on the conveyor.
