The rubber calender is outfitted with different auxiliary devices to accommodate various processes such as rubberizing and frictioning. Each auxiliary device of the rubber calendering machine is designed in accordance with the corresponding production process, and uses rolling bearings on the rubber calender machine. The gear reducers are designed with a hardened surface to reduce wear, and with either a hollow or bored structure, the rolls used are made of chilled cast iron. The rubber calender can be driven by single or multiple motors, each of which feature a stepless speed regulation to widen the application range.
This rubber forming machine is available in two types: regular and precision. The precision rubber calendering machine is equipped with an axis cross unit, pre-loading mechanisms, a pre-bending device, and a device to prevent the calendered rubber material from extending across the connector.
