<p>A high-speed mail stacking and separating apparatus (29) and method including a stack forming assembly (41) mounted for movement from a stack forming position to a stack releasing position. In the improved stacking apparatus, the stack forming assembly (41) is a low-inertia assembly mounted for movement during the time interval between sequentially adjacent envelopes (42) to positively displace the stack (S) out of the stacking zone (Z) to enable a new stack to be formed. The stack forming assembly (41) includes a pair of counter-rotating star wheels (52, 53) having a plurality of Y-shaped arms (56) with one leg (57) of each arm (56) acting as the stack supporting leg and the other leg (58) of each arm (56) acting as the stack impelling leg. A conveyor (43) for conveying the stack (S) from the stack forming assembly (41) to a banding assembly (31) also is disclosed.</p> |
