Our mono-material conveyor belts can be repaired on site in case of damage by using a hot air welding repair.

If there is a cut:
– Make a 45° bevel on both sides of the cut
– Using a hot air welding gun, fill the bevelled cut with a melted plastic seam that is of the same quality as the belt
– Use a cutter to level down the excess material.

In cases where the belt has a heavily damaged area, it is possible to replace an entire section. Our thermowelding jointing techniques allow for this operation to be carried out very quickly on site.

To guide a smooth conveyor belt there are two possibilities:

• Use crowned drums which are very slightly bigger in diameter in the centre than at the sides
• Set up a central tracking guide or two longitudinal guides on the lower surface of the belt.

In both cases, all of the drums must be perfectly parallel (motor, return and back up rollers).

Positive drive belts are very easy to guide:

• For a DEL/DRIVE conveyor belt, we recommend using flanged sprockets. As the belt is not tensioned, the flanges help maintain the belt in the longitudinal axis. For wider gaps, it is recommended to add lateral guide pads.
• For a POSITIVEBELT conveyor belt, guidance is made automatically thanks to the drive sprockets.
• In the case of a DEL/SYNC conveyor belt, the channel on the conveyor bed ensures central tracking.

Antimicrobial treatment is particularly suited to agri-food industries and helps maximise the level of hygiene:

• Prevents bacterial growth
• Eliminates the risk of contamination for transported products
• Reduces odour development
• Optimises food safety
• Improves cleaning and disinfecting procedures.

Smooth mono-material belts guarantee an optimum level of hygiene thanks to their perfectly smooth upper surface that makes cleaning easy. However, they drive under tension, but this in no way eliminates the risk of slippage in oily and wet conditions.
A Positive belt drive doesn’t rely upon drive through tension on pulleys but through the physical engagement of drive teeth on toothed pulleys.
This system eliminates any risk of belt slippage, even in oily conditions. Positive drive belts do not require tension mounting and offer a perfectly smooth upper surface guaranteeing an optimum level of hygiene.
Therefore, positive drive belts have all the advantages of mono-material smooth belts without the risk of slippage, even in oily, wet conditions.

A positive drive conveyor belt combines the benefits of mono-material belts and modular belts without the inconveniences such as poor hygiene or mechanical wear.
Manufactured from polyurethane or polyester elastomer, positive drive belts from the Mafdel range are exclusively mono-material (no textile threads) and are an optimum solution for agri-food industries.
The lower surfaces have teeth moulded into the belt itself which ensure perfect interlocking on the sprockets, while avoiding any risk of belt slippage and bacteria traps.
Positive drive belts offer a maximum level of hygiene and decrease health risks.
Mafdel offers three positive drive belt families that meet most needs.

A conveyor belt allows for continuous movement of merchandise on a horizontal, inclined or declined conveyor.
The upper surface of the conveyor belt is in direct contact with the transported product, and the lower surface is in contact with the conveyors mechanical components.
Conveyor belts are used in many food or standard industries.
Mafdel offers a range of mono-material conveyor belts made from polyurethane (PU) or polyester (PE), for a broad range of industries.
Bespoke conveyor belts can be created according to need: profiles (flat or rounded), sidewalls, perforations, etc.

Customer satisfaction is a priority: Mafdel focuses all of its expertise on your applications.
Several solutions are available so that you can choose the product that is best suited to your needs:

• The selection guide: it lets you make a first product choice for your application
• Our technicians: they are there to answer your different problems and provide you with perfectly suited solutions
• Our research department is also available to design custom products for your applications and meet your expectations.

A harder belt can accommodate greater loads with lower elongation.
However, a more flexible belt can accommodate smaller roller diameters.
Grip for transported products is higher on more flexible belts, but lower grip on a harder belt on the skid plate lets you increase the load.
The choice for the best belt is a matter of compromise and therefore depends on application characteristics.

The colour identifies the type of material: composition, hardness, suitability for food contact, in addition to whether or not there is internal reinforcement.
White, ivory and blue are the colours most often used in the food industry.
