1. Blending Rubber

1. Blending Rubber

Each tire can contain up to 10 different rubber blends.
The blend determines the subsequent characteristics of various tire components. In addition to rubber and fillers, numerous chemical additives are heated and combined with one another as activators and blending aids etc.

Tire Industry - 1EN

Technical Requirements of the Belts

The belts must be exceptionally robust and resistant to incisions, have good release properties and be able to withstand the chemical additives. In some blending processes, water has to be conducted away via the belt.



Directly after the blending process, the finished blend has to be conveyed at a product temperature of up to 175 °C.

Our Solution

Forbo Movement Systems supplies both fabric-based belts (Siegling Transtex, Siegling Transilon) and plastic modular belts (Siegling Prolink) for individual sections of the compounding facility. This portfolio offers optimum belts for any compounding facility.

Different surface patterns on the belts decrease the contact area



to the blend and improve the release properties of the hot and sticky rubber. Resilient coatings and robust fabric designs ensure long services lives and smooth operations. Our PVK150 MF BXB-NA black FR (Siegling Transtex) is used after the kneader and is 100% silicone free.

Other Information

The fabric-based types (Siegling Transtex, Siegling Transilon) are easy to splice with mechanical wire-hook or clamp fasteners.

2. Batch-off

2. Batch-off

Feeder belts convey the hot rubber sheet from the compounding facility into a dip tank. The sheet is brought up to ambient temperature in the cooling section. A pendulum places the material on pallets in specified batch lengths/weights.

Tire Industry - 2EN

Technical Requirements of the Belts

The sheet is conveyed at large angles of incline (in some cases vertically) in front of and behind the cooling section. In addition to chemical resistance, good release properties and exceptionally good grip



are vital at this step in the process. When the rubber is immersed in the dip tank, the belt needs to be consistently waterproof and have a large open area.

Our Solution

The Prolink series 8 modular belt was developed for industrial applications and is the number one choice for conveying in this area. The robust modules have just a one-inch pitch and come in various designs and materials. Each belt can be customized to the type of conveying concerned.


PA-HT capable of withstanding temperatures of up to 155 °C can convey the sheet while it’s still hot. Different surface patterns cut the contact area to the sheet and offer good release properties. The belt offers excellent grip and with rounded ribbing also conveys the rubber sheet gently. Belts with large open areas make immersing the rubber in the dip tank especially efficient.

Other Information

Series 8 Prolink plastic modular belts can be quickly made endless on the conveyor. It’s also easy to replace damaged modules or shorten belts.

3. Extrusion and Cooling

3. Extrusion and Cooling

Two very different sub-processes come together at this step of the process. First of all, the rubber sheet is extruded and injected through dies in defined cross sections from which tread and sidewalls are made later on. After passing through a cooling tray, the strips are either cut to length ready for tire building or rolled up.

Tire Industry - 3EN

Technical Requirements of the Belts

The various sub-processes require the belts to have specific characteristics. Some feeder belts to the extruder must be suitable for metal detectors. Behind the extruder, the belt needs to be able to withstand temperatures right up until cooling tray and have good release properties, it must also be possible to use it under water and be exceptionally resistant to incisions.

4. Calendering

4. Calendering

The calendering process produces the tire’s inner liner and its carcass. The material (the inner liner or the carcass with the fabric/steel cord positioned between two layers of rubber) is heated up and rolled to the requisite thickness. After passing through a cooling section, the strips are either cut to size ready to build the tire and stacked or rolled up.

Tire Industry - 4EN
Calandered rubber - reifenindustrie

Technical Requirements of the Belts

Good release properties and superior resistance to temperatures are vital for this process. The cutting process requires belt material that can withstand incisions.

Our Solution

The entire process can be fitted with Siegling Transilon conveyor and processing belts.

Double-ply belts with polyester tension members and urethane-impregnated surfaces as well as NOVO belts made of polyester felt play a pivotal role in ensuring the process is reliable. The surface of the top face makes exact positioning and therefore precise cutting possible.
