Surface Belt Layers

Surface layers can be applied on V-belts, timing and flat belts to transport material or to protect the surface of belts and transported material.

The choice of surface layers depends on the type of machines and transported material, the temperature of the transported material and the ambient temperature, the size of the pulleys, etc. Specification of the surface layer is determined by the material and thickness of the layer.

Fabrics on the back and teeth can be combined with all other layers.

• Fabric on the Teeth or Back of the Belt
• Rubber Surface Layers
• Plastic Surface Layers (PVC and Polyurethane)
• Foam Surface Layers
• Special Surface Layers

Fabric on the Teeth or Back of the Belt

Special polyamide fabrics make it possible to reduce the coefficient of friction and reduce noise in high-speed drives. They are very useful in applications with sliding surfaces or in accumulation. Polyamide fabrics with antistatic properties are also available.

Rubber Surface Layers

These are surface layers of various mixtures of synthetic and natural rubbers. Thanks to the high coefficient of friction of rubber and high resistance to high temperature, they are used in many different transport applications: in the paper industry, the ceramic industry, the wood processing industry, the glass industry, on labelling and packaging machines.

Plastic Surface Layers (PVC and Polyurethane)

PVC surface layers have a high coefficient of friction and good resistance to acids. Thanks to their versatility, they are used in many applications in the paper, glass, ceramic industry, in labelling and packaging equipment. They allow use in the processes of the food industry.

Polyurethane coatings of various thicknesses and hardnesses are the ideal solution in many applications in the woodworking, ceramic and glass industries. Polyurethane substrates approved for contact with food can be supplied on request.
