Erko offers 2 systems: The discontinuous weigh pan system Digi Balance and the continuous weight belt system EBWM. Booth systems can be attached to bale openers or metering stations.

The amount of weighing systems is depending on the number of different fibers being used. The Weighing system feeds the fibers onto the conveyor belt EFB underneath. The fiber lay-down is arranged in a sandwich form and is transported to the mixing roller type EMZL where the fibers are further blended and pre-opened.
