Endless Belts – What are they and what are they used for?

From agriculture and construction to industrial manufacturing and commercial food production, industries across the board use endless belts to transport materials with maximum efficiency. Keep reading to see how endless belts can best benefit your business.

Understanding Endless Belts

What Are Endless Belts?

Endless belts are continuous belts that are used to transport materials during the production process. By reducing the need for manual labor, endless belts increase production efficiency.

The “endless” part of endless belts means they have no seams or joints. They are typically made with some type of rubber—like urethane, neoprene, or nitrile—and come in various dimensions and surface profiles. Defining features of endless belts are their elasticity, durability, and resistance to abrasions and chemicals.

5 Different Types of Endless Belts

When purchasing endless belts, you have five main types to choose from. Check out their key features below.

  1. Flat: Flat endless belts are used for commercial and industrial conveyance systems, like those used on assembly lines. They offer reliable movement and are versatile, efficient, durable, and simple.

  2. Conveyor: Industrial conveyor belts allow for the continuous movement of materials on a pulley system.

  3. Ribbed: The thick ridges on ribbed endless belts have a coarser texture than other belt materials. The benefits of this endless belt type include flexibility, quiet operation, and clean production runs.

  4. Rubber: Rubber endless belts offer greater flexibility than metal endless belts. They’re also resistant to tears and abrasions.

  5. Timing: Endless timing belts are a type of tooth belt used with a pulley system. They are corrosion and stretch-resistant and allow users to modify belt speed. Their benefits include energy efficiency, low maintenance, minimal noise production, versatility, and clean operation.

6 Benefits of Endless Belts

Endless belts offer six main benefits to users across industries.

  1. Truly endless belts have no seams or splices that could fail. They’re well-balanced and run smoothly, which reduces vibration for less strain on the system.
  2. They offer the highest level of accuracy, which results in optimal performance and a longer belt life.
  3. They’re easy to maintain.
  4. They can be run at higher speeds, making them reliable for high-volume production runs.
  5. They offer better tracking during operation.
  6. They have bi-directional capabilities.

How Are Endless Belts Made?

Belts are constructed from raw rubber and fabric on metal mandrels and open press machinery and vulcanized to a homogenous belt. They’re produced under tension, allowing the process to maintain and control fabric stability. After the vulcanization process, the belt is sent to finishing, where it’s trimmed and ground to the required thickness.

4 Endless Belt Applications

  1. Tube winders: Also known as spinning belts, tube winders are designed for industrial applications for paper machine winders in the spiral winding industry. They’re known to increase manufacturing efficiency.
  2. Conveyor belts: Conveyor belts are used in factories for manufacturing purposes, like food processing and woodworking. They’re used to transport materials during the production process and come in various sizes for various applications.
  3. Harvesting machines: Endless belts accelerate the harvesting process in the agriculture industry. They’re mainly used for heavy machinery like balers and potato harvesters.
  4. Extrusion belts: Endless belts are used for aluminum extrusion applications in the plastic and aluminum extrusion industries.
