Dandy Rolls and Open Wire Rolls

AKUFORM dandy roll systems are efficient formers to improve the paper quality and are used on Fourdrinier machines to improve sheet formation. In modern paper machines, these systems are nowadays an integral part particularly in the production of decor papers and cigarette papers. The dandy roll diameter is determined according to the production speed. BELLMER supplies dandy rolls with diameters ranging from 600 to 2,000 mm and hence for speeds up to 1,100 m/min.

Additional equipment accessories such as drive, spray tube, steam pipe, trays and covering hoods make the dandy roll body a complete AKUFORM dandy roll system. Both the line-up and design of these components are fundamental features to assure a reliable and safe functioning of the entire system. Each individual component of the machine reflects the expert knowledge, which BELLMER acquired over the past decades.

The perfect solution to avoid water splashes

Every dandy roll in operation induces water splashes, i.e., at the point where the dandy roll is separated from the fibrous web, little drops of backwater and spray water are projected from the surface of the dandy roll body onto the paper web. For most papers, the water splashes cause quality losses (markings from water drops on the paper web) or operating troubles (dirtying of cut squirt or press section).

To meet these challenges, we have developed the AKUFORM RX dandy roll system, where a special water collecting device catches the water splashes so that the paper quality will not be impaired.

Nowadays, AKUFORM RX dandy rolls are common standard with diameters from 800 mm and for all critical papers. For dandy rolls that do not yet have water collections systems, we offer these as a retrofit.


Open wire rolls

We also supply individual dandy rolls with smooth fabric as well as robust open wire rolls for paper and board machines.
