An apparatus (100, 700) for inverting a mail item (510, 520, 530, 540, 710, 715) having a leading and trailing end (531 L, 531 T), the apparatus comprising:
- a rotatable cage assembly (130) having an input guide section for receiving the mail item from an upstream direction of feeder path by the leading edge (531 L) of the mail item, the rotatable cage (130) configured to:
rotate about an axis of rotation; and
invert the mail item during rotation of the rotatable cage about the axis of rotation (170, 721);
- a bi-directional drive mechanism (200) to convey the mail item while it is contained in the rotatable cage (130) assembly in accordance with a variable motion profile, the drive mechanism configured to:
convey the mail item with its leading end (531 L) forward in a first direction (30) away from the input guide section of the cage assembly (130), and
convey the mail item with its trailing edge (531T) forward in a second direction towards the input guide section during rotation of the rotatable cage about the axis of rotation such that the inverted mail item exits the rotatable cage (130) in a direction towards a downstream direction of the feeder path. |
