Roll Forming Machine Roll forming machines come with various features and equipment, depending on the specific application needs. Some of the common features and equipment include decoilers, feeders, guides, roll tooling, cutoffs, and stackers. The decoiler is a machine that is used for unwinding metal sheets to feed into the roll forming machine. The feeder is used to control the speed and movement of the metal sheets. The guides ensure that the metal sheets are properly aligned and positioned for proper forming. The roll tooling consists of the roll dies and other components that shape the metal sheets. The cutoffs are used to cut the roll-formed profile to the required length, while the stackers are used to collect the finished profiles.
