Shell Press Coil Change Process in Beverage End Manufacturing
This video provides a step-by-step look at how a coil change is performed in beverage end manufacturing, specifically for the Shell Press. The Shell Press uses aluminum coil to form shells — ends that have not yet been scored or had a tab applied.
Steps in the Coil Change Process
1) Coil Placement on the Upender
A new aluminum coil is first placed on the upender (also known as the downender). This equipment rotates the coil from a vertical to a horizontal position, aligning the central hole of the coil with the mandrel orientation.

2) Transfer to the Coil Car
Once in position, the coil is transferred to the coil car. The coil car moves the new coil into position near the uncoiler.

3) Loading onto the Uncoiler Mandrel
The coil car elevates the coil and loads it onto the uncoiler’s expanding mandrel, securing it for unwinding.
4) Replacing the Used Coil
The uncoiler rotates, swapping out the old, depleted coil for the new coil, preparing it for feeding.
5) Feeding the New Coil into the Press
The aluminum strip is first fed into the vertical loop stand, which helps regulate coil tension. From there, it moves into the Shell Press infeed, ready to resume shell production.
