The core of the DuoFormer D is the top wire suction box, the forming box with pneumatically engaged forming strips and a separation suction box.
This so-called D part can be installed in existing top wire formers of various types. With the DuoFormer D, an older roll former becomes a modern strip former with counterblade technology. The existing rolls and machine frame parts can often be reused, which lowers the investment costs.
Through an analysis of the pre-dewatering section, the appropriate position of the D part is calculated. With older formers, the dewatering capacity can be increased with a larger top wire suction box and, if applicable, a double-chamber separation suction box.
