This device accumulates a certain quantity of aluminium to supply the progress and to maintain it well aligned. Its presence is of fundamental importance, as progress requires instant aluminium equal to the longitudinal development of the container.

The speed of the feed is raised when the frequency of the beats is high as well as when the container is large.

The aluminium  is accumulated in the Accumulation Zone between the fixed rollers and the mobile rollers.

The lubrication device is usually assembled on the Foil Storage Aligner and is used when the aluminium has not been sufficiently lubricated by the rolled section.
