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.

Claims7

Dependent claims

A method for transferring rolls of web material wound on a production core and supported by a production reel spool shaft extending through said core, said shaft having first and second ends extending beyond said core, said method comprising:

removing one of said rolls including said shaft with said core and said wound web material, from production equipment;
supporting said shaft of said removed roll only at one of said first or second ends;
aligning a mandrel with the other of said first or second ends;
while said shaft is supported only at said one end, moving said roll axially along said shaft toward said mandrel;
continuing to move said roll off said shaft onto said mandrel;
wherein the roll of web material is supported exclusively at the core throughout transfer from said shaft to said mandrel.
