The basic part spools or steel sleeves for coiling of foil rolling mills

How can the thinnest foil be coiled from the rolling mill line to the storage system?

Foil rolling is an aluminum-specific process — no other material can be rolled down to a thickness of 5 or 6?μm.
The final step in the flat-rolled product production line is to wind the aluminum strip or foil onto spools that are specifically tailored to downstream production processes.
After strict inspection and dynamic balance testing, the custom spools or steel sleeves are shipped to the client.
