The suction forming roll for excellent formation
With the EvoFlow product portfolio, Voith has developed an optimized roll design for the specific application. The EvoFlow F forming suction roll located in the forming section of fast running paper machines is used for initial sheet formation. As the sheet forming takes place immediately after the
stock has left the headbox, high demands are placed on the forming roll. The drainage capacity of this suction forming roll as a rotating drainage element is mainly determined by the diameter, the wire wrap angle and the vacuum level in the suction zone. Depending on the respective paper grade to be produced, Voith also offers customized patterns with countersunk holes and secondary structure, or honeycomb structures with optional shrink-on or metal sleeves.
