Manufacturing a tyre not only requires the latest technology, precision instruments and qualified people but also requires qualified suppliers.
Working together with our customers and leading research institutions, we have developed a full range of belting products for the Tyre Industry.
With the unique product portfolio of fabric based Process and Conveyor Belts, as well as uni Modular Belts, Ammeraal Beltech provides the best technical belting solutions for all tyre manufacturing processes.

Le configurazioni attuali di fabbrica e dei processi potrebbero variare, ma i nostri esperti del settore le conoscono tutte.
Gli ingredienti che caratterizzano ciascun tipo di pneumatico devono essere pesati e trasportati nel mixer.
Principali sfide
- Mistracking of the belt due to heavy load (load not always spread over the entire belt width)
- Sliding of raw materials on the belt surface
- Belt elongation due to heavy load causes more maintenance
Soluzioni
- Ammeraal Beltech Synthetic Belts with folded edges against fraying and v-ropes for better tracking
- uni Modular Belts to solve all issues
Raw materials are mixed into a homogeneous rubber compound. There are two different mixing types in the market:
- ‘Banburry’ – material mixed between 2 big drums (3-4 stages)
- ‘Continuous mixing’ – material mixed between two belts (sandwich) for 15-20 minutes
Principali sfide
- The rubber compound is very sticky
- Compound temperatures between 120 °C to 180 °C
- More change over due to multiple recipes
Soluzioni
- Ammeraal Beltech Synthetic Belts with Silam coatings for very good non-stick characteristics and resistance against the high temperatures
- Felt or Fabric Belts for the infeed and outfeed conveyors
- Mill to mill transport with our plastic modular solutions (available as metal detectable)
La mescola di gomma deve essere conservata su pallet prima di passare alle successive fasi di produzione. Per evitare che la gomma si appiccichi viene immersa in un bagno di acqua saponata, asciugata e depositata con un’unità wig wag su pallet.
Principali sfide
- Very dirty environment (soap, water, temperature ~80° C)
- Rubber can be very sticky (bad release properties of the chosen belt)
- Belts in the dip tank are difficult to change
Soluzioni
- Ammeraal Beltech Synthetic Belts with impregnation have non-stick characteristics
- Our Modular Belts with the biggest open structure in the market to guarantee a good soap / water penetration in the dip tank
- Unique ZipLink® range for easy installation and less downtime
Durante il processo di calandratura la gomma viene pressata su tessuti e cavi metallici, che andranno a formare il corpo del pneumatico.
Principali sfide
- Rubber can be sticky (bad release properties of the chosen belt)
Soluzioni
- Ammeraal Beltech Synthetic Belts with impregnation have non-stick characteristics
- Our Modular Belts for longer lifetime and less maintenance
- AmWind liner solutions
inished steel cord (for Breaker Belt, Body Ply) and textile cord (Body Ply, Strip) is cut into appropriate sizes, shapes, and angles depending on the desired contour of the tyre.
There are three different cutting methods:
- Guillotine
- Rotary
- Hot blade
Principali sfide
- Conveyor belts can be damaged from the cutting device
- Vacuum is necessary for easy transport
- Replacement of timing belts on the feeder lines
Soluzioni
- Ammeraal Beltech Synthetic Belts with different covers specially chosen for the used cutting methods
- Quick fastener solution or welding solutions for timing belts
- Our AmWind liner solutions
Extrusion is the process by which heated rubber (80 °C – 120 °C) is pushed, under high-pressure, through an extruder head, to pre-shape the rubber. The next step is the cooling line where the rubber (tread, sidewall) is cooled and the dimensions are stabilised. The new semi products need to be stored before the next production step (TBM) and this is done via winding units (liner) or other storage systems.
Principali sfide
- Friction on the feeder belt must work perfect (no slippage but still good release)
- No mechanical fasteners allowed due to possible imprint on the rubber
- Long cooling lines are needed to cool down the rubber
- Pollution or waste due to damaged liner materials
Soluzioni
- Ammeraal Beltech synthetic belts with impregnation to have non-stick characteristics
- Our plastic modular belts with an open structure to guarantee a good water penetration in the cooling lines
- Non fraying liner material to avoid rubber pollution
- AmWind liner solutions
This is a mechanical process by which multiple rubber layers are pressed in a multi-roll calender towards one homogeneous rubber layer. An alternative is rollerhead equipment. The rubber compound plasticised in the extruder is conveyed via a wide extrusion die directly into the roll nip of a two-roll calender.
Principali sfide
- Rubber can be sticky (bad release properties of the chosen belt)
Soluzioni
- Ammeraal Beltech Synthetic Belts with impregnation to have non-stick characteristics
- Our Modular Belts for longer lifetime and less maintenance
- AmWind liner solutions
The first step in final finishing involves the tyre-building machine (TBM), with over 40 components that work to form the green tyre.
Principali sfide
- Rubber does not release from belt
- Low coefficient of friction between belt and rubber causes rubber to slip
- Many parallel running timing belts to accommodate extra-wide rubber leads to different elongation and mistracking
Soluzioni
- Ropanol Belts offer good release of sticky rubber
- Grip covers available
- Ultrasync Belts with widths up to 1000 mm
Curing is the process of applying pressure to the green tyre in a mould in order to give it its final shape, and applying heat energy to stimulate the chemical reaction between the rubber and other materials.
After the tyres are cured in the press, they are often cooled down on a conveyor belt and then transported to the trench line (collector line).
Principali sfide
- Temperature impact during cool down phase
- Mistracking of the conveyor due to temperature impact and wrong material combination
Soluzioni
- Ammeraal Beltech heat resistant Modular Belts
- Our roller top belts for the trench line
Dopo le presse di vulcanizzazione, i pneumatici vengono raffreddati prima di passare all’ispezione e allo stoccaggio. I pneumatici finiti devono essere gestiti con cura; di conseguenza, vengono utilizzati nastri con rullini di trasferimento.
Principali sfide
- Tyres can jam on the belt, requiring manual intervention
Soluzioni
- Gentle handling from Felt NPF Belts and uni Modular Belts RTB M1 and M2 eliminate jams
Finished tyres need to be stored (short term) before they are transported to the hubs of the sales channels.
This storage has a demand of intralogistics where conveyor belts are often used.
To quickly load and unload trucks it is common to use telescopic loading systems.
