When it comes to food processing, the importance of having an uninterrupted production line is paramount. One key element to achieving this is selecting and maintaining the canvas belts used in the process. While selecting the size of the canvas belt is essential, so too is keeping an eye on the belt’s condition. To help identify potential problems with cotton canvas belts, commonly used in food manufacturing, this guide provides an overview of belt slipping, tracking issues, tearing or puncturing, and fraying edges. Furthermore, preventative maintenance (PM) tactics such as daily inspections, regular lubrication services, and cleaning are discussed to maximise cost savings.

Belt Slipping

Belt slipping is a common issue with canvas belts in food processing, interrupting the production line. Potential causes may include misalignment of the drive and idler pulleys, improper tension, improper splicing techniques, and incorrect tracking settings. Proper alignment should be established, tensioners adjusted, and splices re-tensioned to fix belt slipping. Additionally, tracking should be checked and adjusted, and lagging or special pulleys should be installed when needed. These steps can help ensure that the canvas belt runs smoothly, with no interruptions.

Tracking Issues

Regarding efficient and smooth food production, tracking issues can be a major problem. Tracking issues are defined as the conveyor belt running off the side of the conveyor or becoming misaligned. Potential causes of tracking issues include an incorrect idler, belt tension too low, damaged pulleys, or worn-out rollers. It’s important to check the idler and tensioning systems, inspect the pulleys and rollers, and adjust or replace any damaged parts to fix tracking issues. Keeping the conveyor belt clean and debris-free is also important, as this can cause tracking issues.

Tearing or Puncturing

Canvas belts in food processing are susceptible to tearing or puncturing, which can cause major setbacks in production. Potential causes of tearing or puncturing include sharp objects, incorrect belt tension, or abrasion of materials. To prevent such issues, it is important to inspect the belts regularly and make sure that all sharp edges are protected. Additionally, the tension of the canvas belt should be adjusted according to the manufacturer’s guidelines. They need to be replaced immediately to fix torn or punctured canvas belts. With timely detection and repair, canvas belts in food processing systems can remain in optimal condition and help ensure an uninterrupted production line.

Fraying Edges

Fraying edges or frayed edges are a common problem with canvas belts used in food processing. It occurs when the edges of the belt become worn or frayed due to continuous contact with the conveyor system or other processing system elements. This can lead to uneven tracking and a decrease in the performance of the belt. Potential causes of fraying edges include repeated belt flexing, improper tension, and incorrect alignment. To fix fraying edges, it is important to regularly inspect and adjust the belt tension to ensure it is at the correct level. Additionally, replacing the belt regularly with a new one can help minimise the occurrence of fraying edges. Proper belt alignment and installation are also important to ensure the belt runs smoothly and avoids fraying edges.

Sanitising Agents

Sanitising agents such as hydrogen peroxide-based cleaners periodically clean the conveyor systems’ surfaces. This step is important to ensure that the food processing line remains free of contamination and reduce the risk of potential problems with canvas belts. In addition to providing a layer of protection against germs and bacteria, sanitising agents can also help remove dirt, dust, and other debris that can accumulate on the conveyor system and cause issues such as belt slipping, tracking issues, tearing or puncturing, and fraying edges. Cleaning the conveyor system with sanitising agents regularly is a good preventative measure for maintaining canvas belts in the food processing industry.

Daily Inspections

Identifying potential problems with canvas belts in food processing can be made easier with daily inspections. This involves regularly checking the condition of the belt, as well as any potential wear and tear. This can detect potential problems early and corrective action can be taken before the belt breaks down completely.

Daily inspections should be conducted with the utmost care and attention. This means checking for signs of wear and tear, fraying, stretching, and other damages. Additionally, the belt’s tension should be checked to ensure that it is adequately tight and that the tracking issue is not present. This will help to minimise any potential disruptions to the production line.

Regular Lubrication Services

Regular lubrication services are essential for ensuring the smooth running of food processing conveyor belts. This involves spraying lubricants onto the belt surface to reduce friction and heat. This helps to reduce wear and tear while also minimising the risks of the belt slipping, tracking issues, tearing or puncturing and fraying edges. The lubricants must be applied with precision, as over-lubrication can lead to costly damage to the belt. It is important to use the correct type of lubricant for the belt to ensure optimal performance. The lubrication should be carried out regularly to ensure a safe and efficient production line.


Cleaning is an important part of preventative maintenance for canvas belts in food processing. Cleaning involves completely removing contaminants or foreign substances from the belt’s surface. This ensures that the belt can remain in top condition for longer. All cleaning should be done carefully to avoid damaging the belt’s integrity. The process can include a combination of manual cleaning with a soft cloth or brush and chemical cleaner solutions. The cleaning solution used must be suitable for the type of belt material to prevent any adverse reactions. Regular and thorough cleaning can help prevent accidental tearing or puncturing of the belt, as well as potential tracking issues.


To ensure a smooth and uninterrupted production line, it is essential to identify potential problems with canvas belts in food processing. Companies can maximise cost savings using preventative maintenance tactics such as daily inspections, regular lubrication services, and cleaning. Sanitising agents such as hydrogen peroxide-based cleaners can also help to prevent potential problems. Companies can ensure that their conveyor systems remain safe and efficient by understanding how to identify and fix potential problems with canvas belts.
