Creation and maintenance of the vacuum in the entire stabilization zone are achieved by blowing air at high speed in the nozzle geometries at the entry and outlet and by means of side air knives on the Bubble Sucker.
The vacuum can be set manually by means of a hand flap in the air supply duct. The design of the Bubble Sucker is easy to maintain. DuoTransferFoil Web stabilization between press and dryer section The DuoTransferFoil with drilled roll stabilizes the web on the dryer fabric.
With its use, problems such as edges peeling away, fluttering and the formation of wrinkles on the paper web are eliminated. Web stabilization with the DuoTransferFoil is done by means of a vacuum singles rudolstadtban to Pa that is set via the fan speed. For ropeless threading of the transfer tail, a threading zone can be separated in the system from the entire operating zone. In the threading process, suction is concentrated on the threading zone.
The stabilization zone is sealed using lateral air knives and a machine-wide nozzle at the transition to the first singles rudolstadtban cylinder, which are provided with supply air from the DuoTransferFoil. The DuoTransferFoil with a drilled roll is inserted singles rudolstadtban the DuoCentri NipcoFlex presses and the first dryer cylinder in order to hold the paper web on the dryer fabric.
The difference compared to the TransferFoil with dryer fabric suction roll is that the drilled roll does not have an internal box, and its suction mechanism works according to the DuoStabilizer principle. This design without an internal box saves costs and no back-up roll is required.

TransferFoil Stabilization of paper web between press and dryer section TransferFoil stabilizes the web from the singles rudolstadtban into the dryer section, eliminating problems such as edge detachment, edge flutter and crease formation.
By means of an ejector effect, TransferFoil creates a vacuum up to Pa behind the dryer fabric in the stabilization zone. Use of TransferFoil after a dryer fabric suction singles rudolstadtban facilitates ropeless threading to the nip between the drying cylinder and dryer fabric. No air bubble forms between the dryer fabric and paper web during feed-in. TransferFoil is used to hold the web after a dryer fabric suction roll between the press and the first drying cylinder. This ensures a good performance of the stabilizer roll and helps to extend the service intervals for the stabilizer roll.
A high vacuum in the release zone allows a lower paper draw at same speed.
The sealing system consisting of MultiSeal forms the release zone and in a targeted fashion provides for a high vacuum in the area where the paper web is picked up from the cylinder. This reduces the stresses that act on the still relatively wet and sensitive paper web when it is being removed from the cylinder.
In addition, runability is improved in the particularly sensitive area of the first dryer groups. Fewer breaks and an increase in speed at the same draw are the results.
With MultiSeal Plus, the high vacuum conditions can be optimized and constantly maintained over a longer period or the production speed can be increased. Another benefit is that the lifetime of the strips can be singles rudolstadtban to more than a year. DuoStabilizer Increased runability due to web singles rudolstadtban 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.
With web stabilization, the stabilizer roll is suctioned via the DuoStabilizer, and the stabilization zone is placed under pressure with a vacuum via the bypass of the roll. Sealing of the zone is done with a cost-effective and energy-saving sealing concept called MultiSeal, comprised of lateral air knives and a Teflon seal toward the roll.
The MultiSeal is a mechanical seal that prevents the boundary air layer carried along with the dryer fabric from getting into the stabilization zone. Separation is carried out with a singles rudolstadtban installed separation disk in the roll, an additional air singles rudolstadtban in the stabilization zone, and a flap that separates the suction singles rudolstadtban of the operating zone from the threading zone.
The additional air knife is fed with supply air, and the operating zone is switched off. After threading, the air knife is depressurized, and the operating zone is activated.
The negative pressure of the DuoStabilizer is set with the fan speed. Manual alignment of the individual DuoStabilizers can be done with a manual flap in the suction line. The DuoStabilizer allows a stable and wrinkle-free web run in the dryer section from dryer cylinder to dryer cylinder.
Web tension and shrinkage are thus reduced; in addition, the speed can be increased. DuoFoil Web stabilization in the single-tier dryer section In the scope of rebuilds singles rudolstadtban paper machines with a single-tier dryer that use suctioned rolls known as dryer fabric suction rolls, DFSRthe DuoFoil can be installed over the DFSR in order to singles rudolstadtban 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 runability of the singles rudolstadtban machine. The web is stabilized by means of negative pressure to Pa in the stabilization zone.
The DuoFoil does not have its own singles rudolstadtban to the vacuum system, but rather is supplied through the vacuum of the DFSR. The stabilization zone is sealed off by the MultiSeal and the lateral air knives. The MultiSeal is a mechanical sealing system that ensures high negative pressures with low energy requirements.
With this system the seal strips can be replaced quickly and easily including parts set behind the framing.
Air knives are used for sealing on the sides singles rudolstadtban order to compensate for the deflection of the dryer fabrics and to prevent wear of the dryer fabric. There is also a seal Teflon plate to the roll provided.
For the ropeless threading of the transfer tail, a threading zone can be separated in the system. This separation is created using flaps that are activated automatically during the threading.

As a result, the transfer tails are held securely on the dryer fabric with negative pressure in the threading zone during the ropeless threading.
This increases the reliability of the machine and reduces the threading time. S-Stabilizer Stabilization with unsteady web run or web flutter 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. The S-Stabilizer stabilizes the paper web in the area of the dryer fabric. The dryer fabric guide roll is moved asymmetrically until it dips into the paper web. The number of breaks can therefore be reduced and machine availability increased.
The paper web is stabilized through the use of a vacuum. It is created by means of an ejector effect behind the dryer fabric in the stabilization zone. The vacuum can be set manually through a hand flap in the air supply duct. The MultiSeal mechanical seal prevents the boundary air layer carried along with the dryer fabric from getting into the stabilization zone.
Air knives seal on the sides to compensate for the deflection of the dryer fabric. In addition, there is a seal toward the roll. The S-Stabilizer is used in two-tier dryer sections and allows an increase in singles rudolstadtban due to stabilization of the web run. Hood air supply VentiPipe Improved removal of air moisture 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. VentiPipe is connected to the air supply system of the dryer section. Hot, dry air is brought into the dryer group via exhaust openings.
