Thermoweldable V-belts

Mafdel offers a wide range of trapezoidal belts, to meet most needs:

Polyurethane or polyester elastomer
Wide range of hardnesses
Reinforced or unreinforced
Cogged or plain
With or without top surface cover

v belts

Reinforced V-belts – Polybelt+

The tensile reinforcement in V-belts is constructed of aramid fibres. Reinforcement prevents belt elongation and reduces tension take up during belt installation.

Cogged V-belts

To accommodate a requirement for decreased pulley diameter, Mafdel’s trapezoidal belts can be cogged from 10x6mm section upwards.
It is also possible to increase the depth of the cog to accommodate even smaller roller diameters.

Belt coatings

Covers can be bonded to trapezoidal belts from 10x6mm section upwards.
A wide range of coatings meets handling requirements in terms of grip, slippage and resistance to abrasion or temperature.

Can you save money by installing a positive drive belt instead of a modular belt?

The answer is YES! For each daily wash with a positive drive belt type DEL/DRIVE 50 you save: 62% water and 63% less cleaning time Many of you have asked us this question, especially in the food industry. Each time, we get the same answer, but we have very few figures to back up […]

Process upgrades through belting V4.0

Did you know that the first food grade synthetic coated conveyor belts appeared in the 1960’s? On closer inspection, it is obvious that the 30 glorious years of industrialisation brought innovations in this field, and each new product is pushed by another one that is more hygienic, easier to clean and to use. We have […]

New catalogues

Our 3 new catalogues are the real bibles of the conveyor belt and the themroweldable belt. You will find all the new products for 2022 in 3 editions: thermoweldables profiles, mono-material conveyor belts, positive drive conveyor belts. In order to further our commitment to the planet and to adapt to new consumption patterns, we have […]

Case study: pasteurisation of ham

The needs of this meat producer A customer of Mafdel, involved in pork processing, has opened its doors to us to reveal how our new monolithic belt products work within his plant. Our client, a long standing customer of over twenty years, has previously experienced the benefits of Mafdel’s existing range of monolithic products and […]

Closed

Mafdel will be closed on Friday 24 December, Thursday 30 December and Friday 31 December. Please take these 3 days into consideration for your next orders. We wish you all the best for the New Year!

Case study: sheep offal

Towards optimisation of maintenance and production processes A sheep slaughterhouse has commissioned a set of conveyors designed with two positively driven conveyor belts that transfer sheep offal. The conveyor belts comprise synchronised compartments created by cleats to keep each set of organs separate. The operators can then keep weigh them individually and get a quality […]

What is the HACCP process?

The HACCP (Hazard Analysis Critical Control Point) process is a method intended to reduce the maximum number of sanitary risks in agri-food industries. This method is based on 7 main principles aiming to control risks during the process and to analyse the hazards during verification of the effectiveness of the implemented system. The Mafdel range of belts and conveyor belts helps provide an optimum level of hygiene to satisfy the requirements of this process.

How do Mafdel products help achieve an optimum level of hygiene in the agri-food industries?

One of our priorities is to provide quality products that contribute to compliance with hygiene standards. Our belts and conveyor belts in the agri-food range comply with the most stringent standards and offer characteristics that help attain an optimum level of hygiene:

Our mono-material products do not have textile threads, which eliminates the risk of fraying
Waterproof and rot-resistant products
Easy to clean
Resistance to chemical aggression: solvents, oils, fats, cleaning products, etc.

Using Mafdel belts and conveyor belts also helps satisfy HACCP process requirements.

What is the difference then between flat belts and conveyor belts?

Our definition: - Flat belts have a width of less than 100 mm. - Conveyor belts have a width greater than or equal to 100 mm.

In what case or cases should High Density Polyethylene (HDPE) runners be used?

HDPE runners offer excellent guiding for round or trapezoidal belts. They also help improve the friction coefficient and therefore increase the transported load. > See more details in the Belt runners section

What is cogging used for on v-belts?

Cogging allows increased belt flexibility and therefore reduces the minimum pulley diameter. Cogging cannot be used for driving using a cogged pulley.

How do you weld a reinforced belt?

Our reinforced belts can be welded together in the same way as our non-reinforced belts, using just an iron and clamp. The aramid reinforcement on our belts is resistant to very high temperatures, it does not need the reinforcement to be removed at the joint before welding. Both types of welds (end-to-end and overlap) can be used.

Why use reinforced belts?

Aramid reinforcement stops elongation on our round and v-belts. This allows for use of long-length belts, while at the same time minimising the need for long travel tensioning devices. The maximum allowable load is also higher, especially with our overlap weld.

How are belts measured?

In the case of standard configuration (belt extended between two pulleys with the same diameter), the theoretical belt length is equal to the pulley circumference + (2x the centre distance). For any other configurations, kindly send us a dimensional drawing of the installation. In all cases, the tension system must be returned to its minimum position. Our technicians are available to help you define your needs.

How are belts tensioned?

Exerted tension depends on the type of belt used (from 0.5% to 8% for Mafdel belts – see the catalogue for recommendations). There are two ways to apply tension to a belt:

The conveyor is equipped with a suitable tensioning system: In this case, the tensioner must be set to the minimum, install the belt and adjust the tensioner to apply the belt tension.
The conveyor is not equipped with a tensioning system, or it is insufficient: In this case, you must use pre-tensioning tools comprising a winch and two tightening jaws, which will enable you to pull the belt ends together and then apply the welding process.

If the belt is reinforced, you must take care not to apply excessive force, which could destroy the reinforcement.

How to weld a conveyor belt?

All belts can be endless welded or delivered open for on-site welding. Conveyor belts can be welded in two ways:

Thermowelding: We offer our end-to-end welding kits. Option for hot air welding (adding material).
Fasteners: Belts can also be jointed using polyurethane or stainless still clips (recommended for pulley diameters greater than 120 mm). This type of jointing is highly recommended for frequent assembly/disassembly or for repair.
