4 Roll Calenders

2 Roll Calenders - 3 Roll Calenders - 4 Roll Calenders - Other

Rubber calenders operate by pressing the formulated compounds between rotating rolls in order to consistently form a uniform sheet in thicnkess and width. On 4 roll calender, the stock is passed two times through the two gaps, decreasing its thickness and improving the final quality.

4 Roll rubber Calenders are the most suitable and advance types for production of rubber sheets, rubberized textile and steel cord rubberizing to ensure quality of the product. On majority of 4 roll calenders, “S” configuration is widely utilized, particularly for production of tire components (by hot rubberizing system) that contain metallic cords. Part of the 4 Roll Calenders in the market are equipped with compensation devices as described below:

Cross Axis: Cross Axis is one of most essential systems installed on 4 roll rubber calender. It primarly functions to maintain constant thickness along the entire width of the product. The system is meant to compensate for the elastic deformation occurring due to different plasticity properties of various compounds processed on the calender. Due to that, the contact point between the material and rotating must be modified accorindly, by adjusting the rolls to an optimized point while they are rotating around the central axis.

Roll Bending: This mechanism is also designated to compensate for elastic deformations on the rolls caused by the working loads. While calendaring, substantial stress is generated and exerts forces on the roll housings and the supporting bearings. This device generates counter-force that eliminates these forces. On most four roll calender, this device is installed on the outer rolls.
