“PrimeLineTEX is a completely new technology for specialist tissue making, and is a direct alternative for making high-quality tissue without using the high-energy TAD process.”
PrimeLineTIAC and R&D
The PrimeLineTEX tissue machine has been designed with the high-quality, specialist tissue maker firmly in mind. The existing production technologies for these high caliper and high absorbency products, like Through-Air-Drying (TAD), are generally expensive in terms of capital cost, and at the same time they have been notoriously demanding when it comes to energy use. The PrimeLineTEX has been designed for the production of textured tissue to fully address both of these important issues: energy-consumption comparable to the production of dry-crepe tissue, and quality close to premium TAD tissue.
PrimeLineTEX is available to fulfil all standard market widths, from 2.7 to 5.6 m. The machine speed depends on the product and basis weight, but it can be operated up to 1,500 m/min Yankee speed. The quality of the paper produced is close to TAD, but requires 50-60% less energy.

The PrimeLineVRT machine has been designed specifically to address the energy consumption of dry-crepe technology. Some 95% of global tissue production volume is produced using dry-crepe technology. The VRT in PrimeLineVRT stands for Vertical CrescentFormer, which has been a project focused on further reducing the energy consumption.
PrimeLineVRT is available in all standard market widths, from 2.7 to 5.6 m. The machine speeds are the same when compared to dry-crepe machines and VRT is available as a module to be retrofitted to a dry-crepe machine. The expected energy savings are in the range of 8-12% when compared to a dry-crepe machine. Depending on the product and paper quality, there is an expected gain in bulk of about 5-10% compared to dry-crepe
Both new tissue machine concepts, PrimeLineTEX and PrimeLineVRT, were extensively tested at the ANDRITZ tissue pilot plant in Graz, Austria. Franz Harrer, ANDRITZ Head of Technology, Tissue explains, “As well as being able to visit our tissue pilot plant in person to view their own trials on our latest technology such as the PrimeLineTEX and PrimeLineVRT, we also have the latest in remote visual technology where we can conduct customer trials live and online. Operators using HoloLens visual technology along with support from the Metris Performance Center of ANDRITZ can give the impression that the customer is actually there, on site, viewing and experiencing the trials. All our customers who have taken part in this online service so far have been very impressed with the performance and quality of the experience.”
