Introduction
A patterned conveyor belt is an inclined conveyor belt composed of a patterned covering adhesive on the working surface and a flat covering adhesive and belt core on the non working surface.
Pattern Conveyor Belt · Features
Core materials: Ordinary cotton canvas (CC), polyester cotton blended canvas (CP), nylon (NN), polyester (EP), etc.
Bandwidth: 300 - 800 mm
Pattern height: 5, 10, 15, 20 mm (can be designed per user requirements)
Inclination range: Suitable for 0° - 40°, preventing material from sliding down
Commonly Used Patterned Conveyor Belts
▲ Herringbone Pattern
Feature
There are "human" shaped patterns on the belt surface that are higher than the belt body. The patterns can be open or closed, and each pattern can be divided into three types: high, medium, and low.
Purpose
Suitable for conveying powdered, granular, and small materials with an inclination angle of ≤ 40°, as well as bagged materials.
☰ Striped Pattern
Feature
There are strip-shaped patterns on the belt surface that are higher than the belt body, divided into three types: high, medium, and low. Each type can be further divided into sparse, dense, and other forms according to arrangement spacing.
Purpose
Suitable for horizontal conveying of packaging materials with an inclination angle of ≤ 30°. If the groove is formed, it can replace the herringbone pattern.
● Granular Pattern
Feature
There are granular patterns on the belt surface that protrude from the belt body or are embedded in the belt body. The pits can also be made into square holes, edges, and cloth patterns.
Purpose
Convex granular patterns are suitable for conveying soft packaging materials or materials that require gripping force (such as cardboard boxes) or non-sliding conveying. The concave granular pattern is suitable for conveying granular materials with an inclination angle of ≤ 45°.
⌒ Fan-shaped Pattern
Feature
There are semi-circular (or 1/4 circular) patterns on the belt surface. When the tape is grooved, the pattern is intertwined into a fan-shaped (or semi-circular) shape, belonging to the high pattern category.
Purpose
Suitable for conveying powder, particles, and block materials with a large inclination angle of ≤ 45°.

Composition and Variety
Composition
The patterned conveyor belt consists of two parts: the base belt and the patterned belt.
Common Varieties
Due to different materials being transported and varying inclination angles, the required pattern shape and height also differ. Commonly used varieties include: herringbone, octagonal, fishbone, U-shaped, cylindrical, pockmarked, etc. Or designed according to user requirements — suitable for powder, granular, and block materials with an inclination angle of less than 30°.
Maintenance of Patterned Conveyor Belts
- Keep belts clean during transportation and storage. Avoid direct sunlight or rain/snow immersion, and prevent contact with acids, alkalis, oils, or organic solvents. Maintain at least 1 meter distance from heating devices.
- During storage, maintain warehouse temperature between 18°C - 40°C, and relative humidity between 50% - 80%.
- Conveyor belts must be stored in rolls — never folded. Flip once every quarter during storage.
- Do not use conveyor belts of different types and specifications together. Use adhesive bonding for joints.
- Select the type, structure, specifications, and number of layers of the conveyor belt reasonably based on usage conditions.
- Running speed should generally not exceed 2.5 m/s. For large block or high-abrasion materials and fixed unloading devices, use low speed as much as possible.
- The relationship between the transmission drum diameter and fabric layers, matching of drums, and idler groove angle requirements should be selected per conveyor design regulations.
- Feeding direction should follow the belt's running direction. Use a chute to minimize material fall distance. Shorten roller spacing at the receiving section and use buffer rollers to prevent material leakage. Equip soft material-blocking plates to avoid scratching the belt surface.
Precautions
With the popularization of conveyor belts in industrial production, multiple varieties, high performance, lightweight, multifunctional, and long service life are key concerns for manufacturers. The correct use of conveyor belts is particularly important. The following precautions should be observed:
-
1
Avoid rollers being covered by material causing ineffective rotation. Prevent material leakage from getting stuck between the drum and tape. Lubricate moving parts regularly — but do not oil the conveyor belt itself.
-
2
Prevent the conveyor belt from starting under load.
-
3
If the conveyor belt deviates, take timely corrective measures.
-
4
When local damage is found on the conveyor belt, use artificial cotton for timely repair to prevent expansion.
-
5
Avoid the conveyor belt from being blocked by the frame, pillars, or block materials to prevent collision, breakage, and tearing.
Frequently Asked Questions (FAQ)
Q
What is a patterned conveyor belt and what is it used for?
A patterned conveyor belt is an inclined conveyor belt featuring raised patterns on the working surface to prevent materials from sliding back. It is commonly used to transport powdered, granular, and block materials on inclined surfaces with inclination angles typically ranging from 0° to 45°, depending on the pattern type.
Q
What are the most common pattern types available for conveyor belts?
The most commonly used pattern types include herringbone, striped, granular, and fan-shaped. Each is designed for specific inclination angles and material types. Additional specialty patterns — such as fishbone, diamond grid, sawtooth, and wave — are also available for specific industrial environments.
Q
What inclination angle is suitable for a patterned conveyor belt?
The suitable inclination angle depends on the pattern type. Herringbone patterns support up to 40°, striped patterns up to 30°, while granular and fan-shaped patterns can handle inclination angles up to 45°. Always match the pattern type to your required operating angle.
Q
How should patterned conveyor belts be stored properly?
Patterned conveyor belts should be stored in a clean, dry environment with a temperature between 18°C - 40°C and relative humidity of 50% - 80%. They must be stored in rolls (never folded), flipped once per quarter, kept away from direct sunlight, moisture, and chemical substances such as acids, alkalis, and oils, and kept at least 1 meter from heating devices.
Q
What is the recommended maximum running speed for a patterned conveyor belt?
The running speed of a conveyor belt should generally not exceed 2.5 meters per second. For applications involving large block size materials, highly abrasive materials, or fixed unloading devices, a lower operating speed is recommended to minimize wear and extend belt service life.
Q
Can different types of conveyor belts be used together on the same conveyor system?
No. Conveyor belts of different types, specifications, or structures should not be used together on the same conveyor system, as this can cause uneven tension and operational issues. If joining is necessary, adhesive bonding is strongly recommended to ensure a secure and compatible connection.
