Abstract
In an apparatus for handling rolls of web material, a shaft bearing one or more fully wound rolls of web material thereon are supported from one end in a cantilever support. An external mandrel is aligned with a free end of the shaft. A roll-moving device is positioned to shift the rolls axially along the shaft away from the supported end of the shaft. The roll-moving device shifts the rolls of web material off the shaft and onto the aligned external mandrel, shaft or other support device. The weight of the roll of web material is borne by the shaft and external mandrel throughout the transfer. Once the shaft is removed, the rolls of web material can be handled during further processing from the core.
