The rolling of thin aluminum foil is a very specific process and differs from conventional cold rolling. This rolling mode is reached at thicknesses below app. 70 μm. With decreasing strip thickness, the specific roll force increases, which leads to an increasing elastic work roll flattening in the contact zone.

If the cold mill rolls or hot mill coils have too little crown, the mills will roll out the edges and create edge wave (see Figure 9). This is fairly common in mill master coils. Mill work rolls and backup rolls bend and compress under the vertical loads it takes to reduce plate or sheet coil thickness.

Some of the drawbacks of a mechanical device are: The limited load variety, in that a single tong can only handle a certain range of load sizes. A mechanical tong is typically heavy, especially compared to a beam or lifting frame for the same load size. Finally, the added concern, if called for by the process, of gripping a roll by its body.
