Curved conveyor systems are crucial in many production lines—particularly those dealing with delicate or complex materials that must navigate turns or changes in direction while maintaining accuracy. However, many traditional curved systems come with added complexities: (1) they often require large footprints with extra infeed/outfeed segments, (2) can cause product scuffing during turns, and (3) demand frequent maintenance to keep belts aligned. For industries handling fragile or easily damaged goods, these issues can translate directly into wasted product and added downtime.
Dorner’s new Compact Curve Conveyor (C³) is designed to reduce these complexities and meet the needs of industries looking for a trustworthy compact curved conveyor. Below, we’ll explore the key advantages of curved conveyors, comparing and contrasting them to modular conveyors. We’ll also explore the C³ specifically and compare it with Dorner’s existing modular belt conveyor lineup, including the AquaPruf and 3200 Series modular conveyors.
“The C³ was developed to fill a specific gap in our portfolio – a curved solution that fits into our small, low-profile conveyor line. Unlike our modular chain curves, this belted conveyor eliminates the need for straight sections before and after the curve, substantially reducing the system’s footprint.” – Marco Pardo, Product Manager
Comparing Curved Belt & Modular Conveyors
Dorner’s modular belt conveyors—like the AquaPruf and 3200 Series—are known for their flexibility, especially in wet, washdown, or heavy-duty environments. While these modular platforms excel in high-load or hygienic environments, curved conveyors (like the C³) meet a different set of needs.
Curved Belt Benefits
- Smooth Belt Surface: A fabric belted system is gentle on confectionery, bakery items, or any product that could be marred by an uneven belt surface.
- Low-Profile & Economical: Typically lower in cost and space requirements, offering a simpler, more compact design capable of tight turns without the need for extra infeed/outfeed segments.
- Accurate Product Positioning Through Turns: The C³’s patented curved belt and drive system keeps the product’s leading edge consistent, improving the ease of downstream processes.
- Small Pulleys: Small-diameter pulleys allow for greater accuracy and precision in transferring small, delicate products.
Modular Belt Strengths
- Tough in Demanding Environments: The interlocking plastic modules resist damage and can handle higher loads, making them ideal for applications like heavy product handling or extensive washdowns.
- Complex Layout Possibilities: Modular belts can create multiple curves in a single conveyor path, which is beneficial in space-constrained facilities.
- Wide Range of Belt Types: Cleated, open-grid, and friction inserts are just a few options available to support different product shapes, sizes, and processing requirements.
Key Takeaways:
- Choose Modular for Heavy Loads & Complex Washdown Applications: If you’re moving heavier items or need a belt that can stand up to repeated high-pressure washdowns, Dorner’s modular conveyors (AquaPruf and 3200) might be the best fit.
- Pick the C³ for Delicate Products & Tight Spaces: For small or delicate items that need gentle handling and precise transfers around curves, the C³’s smooth surface and compact design is ideal.

Key Benefits of Dorner’s Compact Curve Conveyor (C³)
Space Optimization
- Compact Design: The low-profile frame of the C³ reduces the conveyor’s overall footprint, making it an ideal solution for tight spaces. This space-efficient design enables the integration of the C³ into existing lines without requiring extensive modifications, maximizing valuable floor space.
- Reduced System Footprint: Unlike traditional modular belt curves that often require long straight infeed and outfeed conveyors, the C³’s seamless design reduces the infeed and outfeed, streamlining the system and further reducing the overall space needed.
Gentle Product Handling
- Smooth Belt Surface: The C³’s fabric-belted system is designed for gentle handling, preventing scuffing, breakage, or deformation of delicate items. This makes it especially suitable for handling confectionery products, bakery items, or any fragile goods that need to maintain their integrity through the curve.
- Precise Product Positioning: The C³’s patented curved belt and drive system ensure that the leading edge of the product and separate lanes remain consistent throughout the curve, preventing misalignment and ensuring the product is correctly positioned for the next step in the processing line.
- Tight Product Transfers: Small pulleys allow the C³ to gently transfer delicate products as small as 2 inches.
FDA & BISSC Compliant
- The C³ is equipped with FDA-approved belts and plastic components and stainless steel bed plates, making it compliant with BISSC (Bakery, Snack, and Confectionery) standards. This ensures that the C³ is food-safe, making it ideal for baked goods, confectionery, and packaged food applications where dry environment wipedowns are required.
Ease of Maintenance
- Quick Belt Change: Designed for minimal downtime, the C³ features a side-driven sprocket system that allows the conveyor to be easily removed and replaced from the system, making maintenance fast and easy. With Dorner’s fast shipping of spare parts, maintenance is far less of a headache, keeping production lines running smoothly with ease.
- Minimal Operational Wear: The low-tension design also reduces wear and tear on the system, ensuring long-lasting reliability and performance.

FAQs
How do curved conveyors work?
What are the three types of conveyor belts?
The three main types of conveyor belts are flat belt, modular belt, and cleated belt.
Here’s some more information on those different types of conveyor belts:
- Flat Belt: A continuous loop that moves products on a flat surface. Ideal for light-duty applications.
- Modular Belt: Made of interlocking segments, this belt allows for flexibility in handling heavier loads and navigating curves.
- Cleated Belt: Features raised sections that help transport products on inclines or keep items in place.
What is a curve belt?
A curve belt is a specialized conveyor flat belt that allows the conveyor system to move materials along a curved path.
These belts are designed to transition smoothly around corners, reducing the need for additional straight sections and optimizing space. Curve belts are commonly used in food processing, packaging, and material handling to keep the flow of goods uninterrupted.
