Habasit conveyor and processing belts are generally made of different layers, with tensile strength provided by synthetic fabric plies. These fabrics are connected with layers of thermoplastic materials in conveyor belts with multiple plies or fabric layers. Most heavy conveyor belts are produced with an interwoven or nonwoven "single ply" construction. The material, thickness and texture of the conveying side depend on the function of the belt.
Cover coatings are mainly made of thermoplastic materials like TPU, TPO, PVC, etc., and elastomer-like rubbers, PUR, etc. – or feature a fabric cover. The running side is usually a fabric, often impregnated with a thermoplastic material, or with special wear-resistant PUR that provides a low and constant coefficient of friction. There are also pulley-side fabrics that feature special low-noise running capabilities.
A wide range of different polymer materials such as thermoplastics or elastomers (rubber) provide all the features required for certain applications. Learn more on our Materials pages.
A well-designed belt surface supports both the secure transport of the goods conveyed as well as the process where the belt is employed. Careful selection is essential in order to find the right belt for each conveying or processing application.
For further information see the surface selection table.
The strength class of each belt is determined by its traction layer material, or the composition of the fabric. The fabric is generally embedded within polymers (thermoplastics or elastomers), which protect it from external influences like humidity or light, as well as from mechanical damage through wear. Despite its low thickness, the tensile fabric provides both strength and longitudinal flexibility, which is essential for dealing with the pulley dimensions and nosebar diameters involved.
Our conveyor and processing belts are produced in open length coils. To run on a machine the belts are cut to the appropriate widths and lengths, and joined to form a closed loop. Depending on the belt materials, the belt is made endless using adhesives (Thermofix method), or with our adhesive-free Flexproof joining method, or with mechanical fasteners (lacing).
