Rieter is your supplier for ideally suitable scanning elements. For every Rieter draw frame Rieter has the suitable scanning elements.
Compared to scanning sliver by means of a fixed-position lever, the well-proven principle of "tongue and groove" scanning rollers shows certain fundamental advantages. "Tongue and groove" scanning rollers produce minimal friction between fibres and metal. This reduces the amount of deposits - an essential issue for a perfect long term count stability. On the other hand, the low friction allows the application of higher compression forces with the scanning rollers on the incoming sliver. Variations in mass can thus be measured more precisely.
The feed funnel for the levelling scanning is unbreakable, which is an advantage by ungently removing of sliver accumulation.
