Once the rubber mixture is ready, it is processed using a series of machines designed for shaping and cutting. These machines include calendering machines, which flatten the rubber mixture into sheets, and extruders, which form rubber into specific shapes.

After the initial shaping, the belts are then cut to size, ready for the curing process.
