Our high-precision four roll calender line is engineered for exceptional efficiency and adaptability in the production of rubber products. Each roller is independently driven by a variable frequency motor, allowing for precise control over the roller surface's linear speed, which can reach up to 60m/min. This capability significantly enhances production efficiency. Additionally, the roller speed ratio is adjustable within a range of 0.5-1, accommodating a broad spectrum of process requirements. The inclusion of a programmable controller enables automatic control over the entire machine, ensuring production adheres to pre-defined process formulas. This advanced control over critical quality factors such as temperature, pressure, roller surface speed, and cord tension is crucial for maintaining product stability.
