Abstract
In an item-handling device, a layer head includes an item layer building platform defining an item receiving plane, the layer building platform being vertically positionable. A puller bar mounts to the layer head and moves in relation thereto within a plane above the item-receiving plane. The puller bar is positionable between a retracted position above the layer building platform and an extended position offset from the layer building platform.
