Abstract
An apparatus for stacking and separating sheets of web material provides a conveyor for transporting the sheets from a source of sheets. The sheets are conveyed in a stream that is aligned in a downstream direction from a source to a stacking location. A kicker mechanism is located along the conveyor to offset sheets in a direction that is substantially transverse to the downstream direction. A stacking mechanism is positioned at the stacking location for receiving each sheet from the conveyor and overlaying each sheet into a stack that extends downstream in a horizontal orientation that is substantially parallel to the ground. The kicker mechanism may include an elastomeric foot that engages and withdraws from each selected sheet to drive it transversely to the downstream direction. The sheets may be cut from a continuous web source.
