In all vehicles, whether they are off road, trucks, passenger or agriculture machines, the tires, are the only contact surface with the ground. The most important figure of the tire is to be safe and provide the best traction. In order to maintain high strength that could on one hand withstand the pressure in the tire in and on the other hand be tough enough to stand the road, reinforcement has to be added to structure. This reinforcement can be done by adding strong materials such as steel and fabric sheets. One of the goal machines that make combination of rubber and textile/metal possible is the calendar.
The metal/fabric is fed from a creel room or let-off unit, at the same time heated rubber is fed on the top and bottom of the metal/fabric sheet. All the layers are pressed to a precise thickness in order to create a precise and uniform sheet in width and thickness. This accuracy of the thickness plays a key role in the production and has high impact on the quality of the end product.
The calender is not only used in tire manufacturing but also in other rubber fields such us: belt conveyor manufactures, rubber sheets manufactures etc. 2 roll calenders are considered a suitable type for production of rubber sheets, rubberized textile and steel cord rubberizing to. 2 roll calenders configuration is widely utilized especially for production of rubber sheets and on limited basis for production of steel reinforced tire components (by cold rubberizing system).
