4-Roll Calender
Besides producing continuous rubber sheets, 4-roll calenders can also handle processes where rubber needs to be combined with fabric or cord materials during production. They can also be used for production work that involves combining rubber with fabric or cord materials. The extra roll gives the calendering process more room for adjustment, which is useful when thickness, surface finish, and rubber application need to be controlled more carefully. These calenders are often used in the production of tyre components, conveyor belt materials, rubberized fabrics, and similar products.
