The four-roll rubber calender is a key piece of equipment in rubber processing, used for pressing and stretching rubber sheets. The four-roll rubber calender available in our store weighs 10,000 kg, features a twin-screw design with an 85 mm screw diameter and a length-to-diameter ratio of 44:1, and is suitable for raw materials such as PLA and PET. It has an extrusion diameter range of 800-1500 mm and an extrusion output of 500-800 kg/h, meeting high-efficiency production needs. This equipment supports customization; with a 600 mm roller diameter, it can produce single-layer, double-layer, and multi-layer PET sheets with widths ranging from 600 mm to 1220 mm. This four-roll rubber calender is currently in stock to meet your diverse production needs.
PLC-controlled four-roll calenders are the industry standard for high-volume, double-sided rubber coating of cord fabrics (tire cord, conveyor belt fabric) . They achieve precise thickness, uniform cord penetration, and high automation through programmable logic control and advanced roller compensation technologies .
Here is a structured overview covering the core functions, technology, and specifications:
| Aspect | Description / Key Details |
|---|---|
| Primary Application | One-pass, double-sided continuous coating (frictioning/ skim coating) of tire cord, canvas, and steel cord with rubber compound . |
| Core Advantage | Doubles productivity vs. 3-roll calenders; eliminates need to flip fabric for second-side coating, ensuring better cord alignment . |
| Control System | PLC (Programmable Logic Controller): Core of automation. Manages speed synchronization, nip adjustment, temperature, and safety interlocks. Brands mentioned: Omron ; Options for bus-mastering systems . |
| Roller Config. | S-type / Z-type / L-type (45° or 30° angles) . Design minimizes roller deflection and facilitates even sheet formation . |
| Precision Devices | Axis Crossing, Roll Bending, Pre-loading: Compensate for roll deflection under load, ensuring micron-level thickness uniformity (±0.02mm tolerance cited) . |
| Drive System | Independent Motor Drive: Each roller driven by separate variable-frequency or DC motor. Allows arbitrary speed ratios between rolls for frictioning vs. coating modes . |
| Thermal Control | Peripheral Drilling: Rollers feature drilled passages close to the surface for rapid, uniform heat transfer (steam, oil, or water) . Typical working temp: 50°C – 150°C . |
| Key Specs | Roll Diameter: 230mm – 900mm+; Working Width: 630mm – 3400mm; Min Thickness: 0.15mm – 0.2mm; Line Speed: 2 – 50 m/min . |
| Safety | Emergency stop buttons (multiple stations), foot brakes, electro-hydraulic braking (braking distance ≤1/4 roll circumference), and emergency nip opening functions . |
⚙️ How the PLC Integrates the Calendering Process (Fabric Path)
In a typical operation, the PLC orchestrates the entire process :
Upper Sheet Formation: Rubber compound is calendered between Roll 1 & 2, forming a thin sheet adhered to Roll 2.
Lower Sheet Formation: Simultaneously, another sheet is formed between Roll 4 & 3, adhered to Roll 3.
Lamination: The cord fabric (warp threads guided via spindle creel and expander rolls) enters the main nip between Roll 2 & 3. The PLC synchronizes speeds so the two rubber sheets laminate onto both sides of the fabric simultaneously.
Post-Processing: The exiting rubberized fabric is pulled via tension-controlled take-off, cooled, and wound.
