The coating or toothed side of the belt can be mechanically machined with regard to specific requirements of transport applications. For example to improve the overall flexibility of the belt the transport layer may be produced with cross cutting.

Temperature influences
When transporting hot objects (above 70 °C) it is necessary to ensure the shortest possible contact with the belt so that its central part is not heated above 70 °C. In the short term the transport layer belt may be exposed to higher temperatures if sufficient cooling is ensured. At temperatures above 60 °C there may be a slight reduction in the load capacity of the belt teeth. Additional safety when designing a belt taking into account this temperature influence is only selected in case of higher load. At low ambient temperatures the flexibility of the transport layer and the flexibility of the toothed belt are reduced, so pulleys of larger diameters are needed. The minimum pulley diameter data is determined for an ambient temperature of 20 °C and a peripheral speed of up to 1 m/s assuming a low load on the transported object. For use on pulleys with less than the recommended minimum diameters please consult our specialists
Mechanical machining
To improve functionality, the belts can be mechanically modified.
Higher back side can be used for such purposes allowing wide range of design alternatives, such kind belts have lower flexibility, so pulleys of larger diameters are needed. Flexibility of these belts can be improved by cross cutting or grooving.
