Hanover, January 2016 – Belting specialist Forbo Movement Systems is adding elastic conveyor and processing belts (the EL line) to its product range. The belts in the new EL line are ideal for short centre distances like those encountered in cross-belt sorters.
Major cost savings due to simple designs
Due to the innovative belt design with semi-elastic fabric tension members, the belts can be stretched or pre-tensioned by 1.5 to 5.0%. The material property ensures the belt can self-track. As a result, it's virtually impossible for belts to mistrack at the sides. EL line belts lie totally flat and are laterally stiff at the same time. As a result, even lateral forces have virtually no influence on how straight the belt tracks.
Take-up devices are not needed for these types of design. Therefore, these are costs that can be saved. Profiles on the belt, grooves in drums and slider beds are not required either. The EL line makes designing machinery straightforward and therefore cost-efficient.
Special surface pattern
The EL line currently offers a choice of two surface patterns: a longitudinal groove (LG) or an inverted pyramid (NP) pattern. The LG pattern has very good grip – particularly for inclined conveying or acceleration applications. NP has friction coefficients which are equally high in all directions. This pattern is primarily used on cross-sorters. Both designs are of course flame retardant, as specified in EN 340 (SE).
Small returns possible
Because of the thin, single-ply belt design, especially small returns with very small drum diameters are possible (Dmin =40 mm). Even small products can be transferred reliably from one belt to the next.
References from renowned OEMs are available and very positive. More elastic types will join the product range in the near future.
