Voith expands its portfolio in the forming section with the DuoFormer CBh – a shoe-blade gap former solution for the fabrication of packaging papers at high production rates.

Due to its compact design, the DuoFormer CBh is ideal for rebuilds where space is at a premium. Its dewatering elements are designed to achieve the best possible combination of dewatering capacity and paper strength with minimum effort.

Using a full ceramic slotted impingement shoe cover design and a high vacuum suction box (HiVac) instead of a suction couch roll, the DuoFormer CBh ensures high dry content.


The solution can be applied in a wide operation window, allowing for sustainable and reliable papermaking. It operates up to a maximum speed of 1,600 m/min. The drainage section’s capacity is exactly designed for desired production rates.
