Suction rolls for highest performance

The EvoFlow suction roll is designed to meet specific production requirements. Shell surface patterns that increase drainage capacity and reduce noise generation allow EvoFlow suction rolls to improve the economic efficiency and operating environment of paper production. EvoFlow suction roll shells and suction boxes are made of stainless and acid-resistant steel. For long-term use in the corrosive environment of the paper machine wet section, Voith uses only duplex stainless steels for the roll sleeve. The combination of material and gun-drilled shells is essential.

Suction rolls for each specific application

EvoFlow F 

The suction forming roll for excellent formation

EvoFlow F

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.

EvoFlow C

The suction couch roll for optimum dryness

EvoFlow C

With the EvoFlow product portfolio, Voith has developed an optimized roll design for the specific application. The EvoFlow C suction couch roll is applied in Fourdrinier sections and high-speed gap formers to alter the direction of travel and to dewater the web. It dewaters the web through vacuum zones and increases the dryness. It even takes over partial drive of the wire. The drainage capacity of EvoFlow C is mainly determined by the diameter of the roll, the wire wrap angle and the vacuum level in the suction zones. Based on these criteria, the design of the former is optimized for specific applications to achieve the desired paper quality.

EvoFlow U 

The suction pick-up roll for optimum web transfer

EvoFlow U

With the EvoFlow product portfolio, Voith has developed an optimized roll design for the specific application. The EvoFlow U suction pick-up roll is used to transfer the web to the press section and dryer section. The reliable and trouble-free function of the pick-up roll is significant for high machine efficiency. The diameter and wrap angle can be considerably smaller, as the EvoFlow U roll is used for transferring the web. Its design ensures that the web has good support at the pick-up point and also at the web edges.

EvoFlow G 

Reliable web transfer with the suction felt guide roll

EvoFlow G

With the EvoFlow product portfolio, Voith has developed an optimized roll design for the specific application. The EvoFlow G suction felt guide roll was developed to hold the web on the bottom press felt, when the top and bottom press felts diverge. The main technological advantage of EvoFlow G is its flexible
application, as the roll can be used in more than one position. Its design ensures that the web has good support at the pick-up point and also at the web edges.

InsiderJet

InsiderJet

InsiderJet is a high performance, axially-oscillating cleaning shower that features a number of self-cleaning needle Jet nozzles, which maintain the suction roll shell cleanliness. This results in increased roll running times and longer service intervals.

HydroSeal 

HydroSeal

HydroSeal is a sealing strip with integrated lubrication for all suction rolls. The patented design from Voith enables lubrication of suction rolls directly on each individual sealing strip. This leads to appreciable savings in water and drive power.
