The rolls of aluminium foil are then slit on slitter rewinding machines into smaller rolls. The coils are formed by running a continuous sheet of metal through a roll slitter. Other MJTs are used on mill motors, bearings, shaft mounts, anchor bolts, and slitter knives. For metal coils, the slitter consists of three main parts&colon; an uncoiler, slitter, and recoiler. The slitter at Wolverley was Thomas Cooke. Slitter rewinders are normally used to slit plastic films, paper and metal foils. Pickle line and #5 slitter remained until final demolition of the plant.
