Product Description

PLC-Controlled Four-Roll Calender for Rubber Cord Fabric Manufacturing

The four-roll rubber calender is essential equipment in rubber processing, designed for pressing and stretching rubber sheets with precision. Our available model weighs 10,000 kg and features a twin-screw design with 85 mm screw diameter and 44:1 length-to-diameter ratio, suitable for PLA and PET raw materials.

With an extrusion diameter range of 800-1500 mm and output capacity of 500-800 kg/h, this equipment meets high-efficiency production demands. Customizable with 600 mm roller diameter, it produces single-layer, double-layer, and multi-layer PET sheets in widths from 600 mm to 1220 mm.

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.

Technical Specifications & Features

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 Configuration	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 Specifications	Roll Diameter: 230mm - 900mm+; Working Width: 630mm - 3400mm; Min Thickness: 0.15mm - 0.2mm; Line Speed: 2 - 50 m/min
Safety Features	Emergency stop buttons (multiple stations), foot brakes, electro-hydraulic braking (braking distance ≤1/4 roll circumference), and emergency nip opening functions

PLC-Integrated Calendering Process

Fabric Path Operation

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.
