“The L in Spiratrack L stands for leggera (Italian for lightweight),” says Filippo Lazzaroni, Area Sales Manager of Feltri Marone. “This is achieved by eliminating rubber from the belt’s construction, offering benefits from easier handling to optimized performance in high-demand environments.”
Feltri Marone Sets New Standards with Spiratrack L

Feltri Marone is once again setting the standard for innovation and quality. The company has recently announced the development of a groundbreaking product, the Spiratrack L, slated for release in 2025. This next-generation bottom belt is designed to enhance efficiency, sustainability, and production quality, underscoring Feltri Marone’s dedication to meeting the evolving demands of the packaging industry.
Spiratrack L’s design is built upon a multi-spiral base reinforced with PET flats, a material already proven in high-performance industries, such as Quantum corrugators. For the Spiratrack L, however, Feltri Marone has tailored a special heat-setting process to maximize durability and effectiveness in double-facer applications.
The multi-spiral base is then coated with a special liquid silicone, which solidifies during thermofixing, forming a durable, consistent layer. This innovative approach yields a belt with a thickness of approximately 3mm and a weight of 3,000 gsm – some of the highest specifications in the corrugated field.
Spiratrack L’s distinctive configuration not only sets it apart but makes it particularly well-suited for specialty box production, where precision and quality are essential.
Energy Efficiency and Sustainability
One of the most significant advantages of Spiratrack L is its ability to reduce energy consumption. As a lightweight belt, it requires less driving force to operate, minimizing the load on the motors of corrugating machines. This streamlined operation is further enhanced by the silicone coating, which provides exceptional grip, preventing cartons from slipping and reducing the need for high pressure from the machine’s shoes.
This results in less wear on the machine components and further energy savings, making the Spiratrack L a highly sustainable solution. Feltri Marone’s dedication to sustainability aligns with broader industry goals of reducing environmental impact, offering customers a forward-thinking, eco-conscious option.
Performance and Versatility
The seamless design of the Spiratrack L, a hallmark of multi-spiral belts, minimizes potential marking on the board – an issue commonly faced with woven belts. This feature guarantees a smooth production surface, crucial for delicate applications that demand high precision.
The Spiratrack L is also compatible with all corrugating machines and top belts, making it a versatile choice that meets diverse customer needs. It pairs seamlessly with top belts ranging from traditional needled options to advanced multi-spiral belts, such as Feltri Marone’s own Spirabelt.
A Synergistic Duo
Feltri Marone has designed the Spiratrack L to work optimally with its Spirabelt product, creating a synergy that enhances both quality and efficiency. Here’s how this combination benefits the corrugating industry:
• Enhanced product quality: The Spirabelt and Spiratrack L combo ensures seamless processing, especially for specialty cartons where consistent quality is paramount.
• Energy savings: The lightweight construction of Spiratrack L, paired with the Spirabelt’s efficiency, leads to significant reductions in energy consumption, making this combination an ideal solution for companies looking to optimize operational costs while reducing their environmental footprint.
This powerful combination reinforces Feltri Marone’s commitment to offering advanced, high-performance solutions for complex production needs, effectively setting new standards in the corrugated industry.
Looking Ahead at the Future of Production
The launch of Spiratrack L marks a new chapter for both Feltri Marone and the corrugating industry. By focusing on rubber-free construction, innovative silicone coating, and a robust multi-spiral base, Feltri Marone has crafted a product that anticipates market demands and exceeds current performance expectations.
Spiratrack L addresses the specific needs of today’s corrugators, from reducing operational costs to achieving high-quality output for specialty boxes. Customer feedback from initial trials has been overwhelmingly positive, highlighting the belt’s durability, efficiency, and ease of use. With a strong focus on innovation and sustainability, Spiratrack L is poised to make a significant impact upon its launch in 2025.
The Spiratrack L Revolution
Spiratrack L is more than a bottom belt – it represents a revolution in the corrugated industry. With cutting-edge technical features, an energy-efficient design, and compatibility with all machine types, Spiratrack L exemplifies the future of sustainable, high-quality production.
Feltri Marone’s innovative approach has once again reinforced its status as a pioneering force in the corrugating industry. By prioritizing innovation, quality, and sustainability, Feltri Marone is prepared to support its customers in a rapidly evolving market.
The year 2025 holds great promise for the company and the industry, as the Spiratrack L sets a new standard for excellence in corrugating belts.
