Components for Papermaking

The CB-Turn is a contactless web turning system. A homogenous and controlled cushion of air turns the paper web from the coating units into the drying section.

The HCB-Turn is a combination hot-air drying and non-contact web turning system. It is used after coating units to ensure a stable web run.

InfraElectric is a contactless drying system that is used in pre-drying after coating units. Continuous power control allows precise output control from 0 to 100%.

The InfraMatic infrared drying system corrects the moisture cross profile with gas-heated infrared radiators. It facilitates continuous moisture control by zone on running webs and increases product quality.

The range of gas-fired heater modules with various modes of operation ensures that the optimum solution can be found for every individual application. The modular design means that a retrofit is simple if requirements should change at a later date.

DuoCleaner Express was developed for effective cleaning of dryer fabrics - for good paper quality and efficient machine operation.

Voith’s CleanLine offers a complete range of cleaning systems to cover every section of your paper machine.

In the scope of rebuilds to paper machines with a single-tier dryer, which use suctioned rolls (known as dryer fabric suction rolls, DFSR), the DuoFoil can be installed over the DFSR in order to stabilize the web. With stabilization zones the DuoFoil supports wrinkle-free sheet edges from dryer cylinder to dryer cylinder. The negative pressure in the stabilization zone is created via the "pre-suction" zone in the DFSR. This increases the runnability of the paper machine.

The DuoStabilizer provides web stabilization in the single-tier dryer section. Due to the ropeless and wrinkle-free web run, the runability of the paper machine is increased.

The DuoTransferFoil with drilled roll stabilizes the web on the dryer fabric. By using it, problems such as edges peeling away, fluttering and the formation of wrinkles on the paper web are eliminated.

Through conversion to internal-only dryer fabric guide rolls with a fabric cleaner, the fabric service life can be extended and the cleaning outlay reduced.

ProRelease+ has an efficient and energy-saving sealing system that ensures stable web pickup in the first dryer groups. A high vacuum in the release zone allows a shorter draw at same speed.

With the ProSafe rescue shell, personnel can be rescued from drying cylinders, creping cylinders, Yankee cylinders, boilers and similar containers with small side access openings.

The RopeRing is a molded steel ring that accurately lines the rope groove. It is precisely adapted to the groove profile and can thus be directly installed.

Constantly rising productivity and quality requirements lead to higher demands on fabric and web run and thus also on the dryer fabric tension. Reliable fabric tensioning systems are therefore increasingly gaining significance. Exactly adjustable and constant dryer fabric tension is the most important precondition.

The S-Stabilizer stabilizes the web if there is a turbulent web run or edge flutter in the two-tier dryer section. In addition, the frequency of breaks is reduced due to the supported web run.

SteamJoints are steam joints with stationary siphons. They reliably dewater at the lowest differential pressure. Costs can be lowered due to low consumption of fresh steam.

The tensioning devices and guides from Voith ensure smooth operation of the machine at all times.

ThermoBars increase the condensate film turbulence in the drying cylinder. The heat transfer in the drying cylinder is improved and drying performance increased.

TransferFoil stabilizes the web from the press into the dryer section, eliminating problems such as edge detachment, edge flutter and crease formation.

The VentiBox hot air blow box is used for ventilating one- and two-tier dryer sections. It prevents the edge of the paper web from turning up and provides for better conditioning of the dryer fabric.

The VentiDoc doctor is for ventilating one- and two-tier dryer sections. It combines excellent doctoring with optimal ventilation of the surrounding dryer pocket.

The VentiPipe hot air blow pipe improves ventilation in the fabric loops of the dryer group and removes moisture more efficiently. Hydrolysis on the dryer fabrics is prevented.

The VentiStabilizer stabilizes the web if there is an unsteady web run or edge flutter in the two-tier dryer section. Therefore edge flutter and the frequency of breaks are reduced.

The EvoRun S holds the web against the dryer fabric, guides it through the dryer section, and thus guarantees a stable web run.

EvoDry drying cylinders remove water from the interior and surface of the web while paper fibers are protected.

TRM analyzes and optimizes all factors throughout the entire roll system. This comprehensive concept increases the availability of the rolls and reduces the number of shutdowns due to roll problems.

The PrevoCut DC (Disk Cutter) is a tail cutter installed in the open draw of two-tier dryer sections. It ensures a flawlessly cut tail.

The PrevoCut STC and DTC high-pressure water jet tail cutters cut a flawless threading tail with the aid of a water jet between 600 and 1,300 bar.

PrevoCut TR and RR are standard knives for the lateral tail cut. The PrevoCut TR cuts tails up to 120 g/m² laterally, and the PrevoCut RR cuts tails from 120 g/m² laterally.

The RopeRing is a molded steel ring that accurately lines the rope groove. It is precisely adapted to the groove profile and can thus be directly installed.

TailBlade is a ropeless threading system that allows reliable threading in dryer sections by means of a doctor blade. It minimizes the threading time and increases production.

The dew point control system hood ventilation technology controls the supply and exhaust air quantities in the dryer section, thus reducing the amount of air and fresh steam required.

The Voith EcoHood dryer section hood encloses the dryer section in a special housing that still allows access for operation and maintenance at the highest level of safety.

The hood and associated machine ventilation system form the core of each drying section. The dewpoint of the hood has a direct impact on the energy costs for drying.

Voith has the right steam and condensate system for your production modification, process-engineering adaptation or optimizing the energy use of your system.

TurboDryer S hot air hoods allow for a faster and more efficient production without extending the dyer section at all!

Impingement jet drying using high-capacity hoods is one of the most energy-intensive drying methods in paper manufacturing.
