In 2026, Perini Constellation celebrates more than ten years since its market introduction, a milestone that reflects how this technology has contributed to redefining tissue converting standards worldwide.
Since 2015, more than 160 lines have been installed in 28 countries across 45 customer sites. From North and Latin America to Europe, Africa, Australia and Japan, Perini Constellation has demonstrated its ability to adapt to different markets, products, and production models.
Today, Constellation represents one of the most significant chapters in sixty years of converting innovation and serves as one of the technological foundations on which VALMET will build the next generation of tissue converting solutions.
Visibly More: the challenge behind Constellation
When introduced in 2016, Perini Constellation addressed a fundamental shift in the tissue industry. Manufacturers needed more than efficiency: they needed products capable of standing out more clearly on the shelf. This led to the concept of “Visibly More”: bulkier, more attractive, and more uniform rolls, designed to enhance every detail of the finished product. To meet this need, Perini developed a technology that differed radically from the standards of the time.
The four-roll revolution
Constellation’s unique architecture features movable rolls that maintain at least three contact points throughout the entire log formation phase. This level of control preserves bulk, softness and embossing definition while ensuring consistent roll quality.
As Giacomo Lapini, Development Mechanical Designer, explains: “The core of Constellation is its four-roll geometry: the circle inscribed within the lower roll trio matches the core diameter, eliminating any compression. The result is unprecedented control over log formation.”
Unlike conventional rewinders, where the start of a new winding cycle is linked to the discharge of the previous log, Perini Constellation maintains continuous product control, eliminating compression and delivering superior results.
“The ‘perfect roll’ is not an aesthetic achievement: it is the promise of preserving, right up to the last sheet, all the value created during embossing and the previous process stages,” states Dario Giannini, Engravings Product Innovation & Senna Pilot Line Manager.
Ten years of field experience
Its worldwide success demonstrates how Constellation has evolved from a breakthrough rewinding innovation into a technological platform with lasting industrial value.
The technology has adapted to diverse product categories, from toilet tissue to kitchen towels and from conventional products to premium solutions using structured papers such as TAD, Advantage NTT, and Advantage NTTe, while maintaining consistent results despite natural variations in paper characteristics, core quality, and operator experience.
“Paper characteristics, core quality, operator experience, and product configurations may vary. Constellation helps keep performance, efficiency, and roll quality under control,” states Dave Knutson, Technical Sales, Valmet Inc. North America.
Constellation and the value of an integrated ecosystem
A fundamental contribution to the evolution of Constellation has come from the Perini Constellation S6 pilot line. Originally created to allow customers to experience the technology firsthand and evaluate its benefits, it has progressively evolved into a research and development platform used to explore new product concepts, embossing configurations, and process innovations. Today, this vision extends further through the integration between the pilot paper machine in Karlstad and the Constellation pilot line in Lucca. Producers can therefore follow product development across the entire value chain, from fibre and papermaking to embossing, lamination and final converting.
Latin America: when technology becomes an industry standard
Latin America stands out as the region with the largest installed base, with 65 lines representing approximately 40% of the global total. The region’s continuous focus on production efficiency and fibre optimisation has contributed to making Constellation a preferred choice among tissue manufacturers.
As Daniel Schroeder, Sales SR Manager LATAM, explains: “Constant innovation for the best product at the best cost: that is what drives the tissue market in Latin America.” Supporting this growth is Valmet’s Joinville facility in Brazil, which serves the entire LATAM region through local manufacturing, technical support, and continuous collaboration with leading tissue producers.
From innovation to enabling platform
Today, Constellation goes beyond rewinding technology. It is a platform designed to simplify production, expand operational capabilities, and preserve the value created throughout the previous stages of the converting process.
As manufacturers pursue more distinctive, sustainable, and high-performance products, Constellation’s value lies in its ability to connect rewinding performance with broader converting goals, supporting product evolution while maximising the innovations developed across the entire process.
“Today Constellation is not only an innovative rewinder, but a platform capable of simplifying production, expanding operational possibilities and enhancing everything created in the previous stages of the process,” states Simone Barsanti, Senior Manager, Rewinding, Converting and Packaging Technology.
Excellence is measured not only by the results achieved, but also by the ability to continue evolving and creating value over time. Perini Constellation. Excellence is built on numbers.
