The Tissue Machines Division provides modern tissue machines including CrescentFormers with conventional press configurations, Through-Air Drying (TAD) technology, and machines with the patented TissueFlex™*) shoe press. Ventilation and drying systems for tissue and other paper and board grades complement the product portfolio.
The Tissue Machines Division is headquartered in Graz, Austria with locations in Canada, Sweden, and the USA.

Gold Hong Ye, Suzhou, China set a new speed record for CrescentFormers with an Andritz tissue machine. In January 2004, the machine ran at 2,100 m/min for five consecutive days producing 13.2 gsm facial tissue. A second Andritz machine at the mill also achieved a speed record of 2,060 m/min producing 17.5 gsm toilet paper. The addition of the patented Andritz PrimePickup™ device in the former section of both machines improved runability considerably.
The current world speed record is also held by an Andritz CrescentFormer tissue machine, at PT. Lontar Papyrus, Jambi, Indonesia. In December 2004, a 32-hour high-speed run was performed at a continuous speed of 2,110 m/min (product: 13.5 gsm facial tissue). Andritz tissue machines now come first, second, and fourth in the international speed rankings for CrescentFormers.
Andritz started up its first 200" wide PrimeTAD™ through-air drying production system with an annual capacity of 80,000 tons, in January 2005. Production is already ahead of the projected ramp up curve. The TAD technology applied is a new Andritz development.
Just 17 months after contract signing, a new wet-crepe tissue machine started up at SCA's greenfield tissue mill in the USA (Barton, Alabama). The machine has a total capacity of 110,000 t/y giving the highest specific production worldwide.
Andritz was selected by Procter & Gamble to modernize a tissue machine at the Neuss, Germany mill. The aim of the retrofit, which was started up in June 2004 after only ten days of rebuild activity, was to increase machine speed and improve paper quality. The Andritz scope of supply comprised a new approach flow system, a new headbox, a "speed-up package" in the wet section, web stabilizing equipment, and an Andritz dust removal system in the dry end.
An EquiDry F high-temperature hood supplied by Andritz to German Papierfabrik Gebr. Grünewald's Kirchhundem mill is responsible for a production increase of more than 25%. After one year of operation with the new Andritz hood, the machine has become one of the highest capacity machines in Europe producing machine-glazed paper.
A new PrimeLine™ CrescentFormer tissue machine equipped with a TissueFlex™ shoe press for Thüringer Hygiene Paper GmbH of Germany saw first paper on the reel in December 2004. The machine is installed at a greenfield site and will produce 30,000 t/y of high-quality toilet and towel paper.
The Andritz Fiber Drying group in Växjö, Sweden is positioned to capitalize on hall ventilation projects for mechanical pulping and pulp drying lines around the world. This is another result of Andritz's position as the full-line supplier of systems and processes for the pulp and paper industry.
The Division provides engineered services, such as machine surveys and machine optimization recommendations. An example of optimization services are the PrimeDry™ TCS (Temperature Coating Surface) measurements on the Yankee cylinder of a European tissue manufacturer's TAD machine. Recommendations based upon these measurements helped the mill improve the Yankee crowning curve considerably, which had a positive impact on the runability of the TAD machine.
- The Division received an order to supply another CrescentFormer tissue machine, including stock preparation equipment, to Hengan, a leading manufacturer of high-quality tissue products in China. The new machine will be the third consecutive installation of an Andritz tissue line for Hengan. It will be erected at a greenfield site in Shandong Province. The new machine will produce 60,000 t/y of high-quality and very soft tissue paper.
- The ICT Group of Italy has placed another order for the supply of a new CrescentFormer tissue machine and stock preparation system. The machine will be installed in Pozuelo de Alarcon, Spain. This is the second greenfield project outside of Italy for ICT. The first project, in Poland, also included an Andritz machine.
- In the market for drying equipment outside of tissue production, Andritz Fiber Drying in Sweden received orders for a paper machine hood and air systems from Holmen Paper Papelera Peninsular in Spain (newsprint production), and from Voith for Adolf Jass in Germany (board production).
- Andritz Fiber Drying in Canada will deliver a wet end mist removal system, Yankee hood with process air system, and tissue machine dust removal system to CMPC's Talagante mill in Chile. From Familia Sancela in Colombia, the unit received an order of similar scope.
For optimum "hands-on" operator training, the Tissue Machines Division developed a tool to provide dynamic simulation of all mass and energy flows in a TAD plant. Operators can virtually run the future paper production line and change settings in a safe, virtual environment.
The patented TissueFlex™ shoe press has been proven in eleven installations around the world. One of its latest features is Machine Direction (MD) shoe movement for the highest operational flexibility. This additional functionality of the shoe press results in gaining more bulk, or achieving higher post-press dryness, giving the operator more flexibility.
A further development of the reel with linear primary and secondary arms is the centerwind assist drive in the secondary arm. A centerwind reel is mainly used in TAD machines to retain the bulk of heavyweight tissue and towel grades. The new PrimeReel™ Centerwind controls very low nip loads sufficient for crease-free winding. Furthermore, it allows winding of larger diameter rolls to increase productivity.
A stable sheet run in the area between the creping doctor and reel is critical to runability. The Tissue Machines Division developed a system of sheet run components, such as air or dust deflectors, suction headers, active headers with low sheet contact, and guiding/stabilizing foils. The new PrimeRun™ system ensures better runability, especially with lightweight tissue at high machine speeds.
