Rubber conveyor belt calendering is a key manufacturing step，The rubber compound is rolled into thin, consistent sheets, embedding fabric plies or steel cords within them, providing strength and dimensional stability for conveyor belts. 

Our machines have four rolls, with advanced features like preloading and cross-axis adjustment for high precision. 
Rollers are temperature-controlled and precisely adjustable to manage rubber's stickiness and hardness,to create consistent, high-quality rubber sheets and coatings.

Chevron belts often use metal frames for central support for sturdiness.

For particularly heavy large-roll steel cord conveyor belts produced for long-distance transportation, even stronger and thicker metal frames are often used for support, facilitating loading and unloading by cranes or large forklifts, while also protecting the conveyor belt itself and preventing deformation due to its own weight over long periods of storage.

For conveyor belts that cannot be cut to short lengths, an eyeglasses roll can be formed by winding the belts at both ends towards each other, or by tightly winding an oval metal core on an automated winding machine to form an oval roll.  These satisfy the needs of long-distance transportation and adapts to the height restrictions of trucks or containers, enabling smooth land and sea shipment.

The rainproof cloth covering the outer packaging of conveyor belts is usually made of high-strength, weather-resistant synthetic materials such as polyethylene (PE) or polyvinyl chloride (PVC). Sometimes it is reinforced with woven fabric.

Its main functions are to prevent moisture, sun, and dust, and to protect the conveyor belt from environmental damage during transportation and storage, thus ensuring its quality and performance.

The choice of outer packaging for each type of conveyor belt depends on various factors such as the type of conveyor belt, transportation environment, and storage conditions, or it depends on the customer's order requirements.

Product identification is generally fully displayed on the outer packaging surface.
The company's standardized printed packaging cloth features a clear and complete company information.

If customers have additional requirements regarding the format of the product specifications, our production department will make flexible adjustments and accurately spray them clearly on the packaging cloth. The goal is to ensure that product specifications and quantities are clearly distinguishable from all angles, facilitating transportation and daily use.
