ANDRITZ SPECTRUM Podcast

The Through-air Drying (TAD) process has been well accepted across the tissue industry as a major breakthrough in terms of final product quality; however, the process is notoriously known for its excessive energy demands. ANDRITZ has come to the rescue with the ATAD concept, which is set to revolutionize the energy-intensive demand of TAD production.

ANDRITZ has tackled the TAD energy challenge head on by launching ATAD (Advanced TAD) - a groundbreaking innovation designed to slash drying energy use by up to 20%. Crucially, the energy reduction takes place while preserving the premium quality that makes TAD so appealing.

Panelboard producers have a major challenge when balancing fiber quality, energy consumption, and raw material efficiency. Since 80% of the board is wood fiber, any small variation in fiber length or width has a huge impact on the final product. Traditionally, quality checks are done offline and intermittently, meaning operators had to rely on experience rather than data. The biggest challenge is how to gain visibility and control, knowing what’s happening in real time.

To alleviate these challenges, ANDRITZ has developed MDFEye, an innovative measuring system that continuously analyzes fiber properties right after refining, using machine vision and data analytics...

Maximizing efficiencies and flexibility on paper machines is essential in the highly competitive market of paper and board production. Producers are now actively looking for flexibility in new machine lines or alternatively have reached the limit of their existing forming technology.

ANDRITZ‘s PrimeForm TW Shoe-Blade GapFormer provides a highly flexible solution that enables strength and formation with operating speeds of 1600 m/min and a wide range of grades and furnishes, with single-ply basis weight references from 30-250 gsm.

As well as for installations in new machines, the former is ideal for fast and uncomplicated rebuilds as the basics of the...

One of the toughest challenges in the production of nonwovens is
maintaining product uniformity at high speeds. Issues like the 'smile effect,' where fiber accumulates on the edges of the mat, lead to quality losses and wasted material. Producers are also under pressure to cut costs, save fiber, and reduce manual interventions, all while meeting sustainability goals such as lowering energy usage and emissions."

The actual process of producing nonwovens can be described as similar to baking bread - but at industrial speed. Fiber mats have to be laid evenly, layer after layer, without clumping at the edges or thinning...
