As a result of a synergistic effort involving the company as a whole and its skills, Comerio Ercole has recently sealed a deal with an European group for the construction of an impressive “giant” 3-roll high temperature calender with a 6800-mm roll working face.

This “giant” calender is conceived for the production of innovative articles, obtained from thermoplastic materials, also recycled, for thermal/acoustic insulation applications. No doubt it is one of the biggest machines in the world for roll size, made of special forged steel, featuring mono-block design and high process temperature (up to 260°C).

To ensure the perfect fluid distribution, the roll bodies are designed and manufactured by Comerio Ercole with peripheral drilling technology in order to achieve a maximum delta temperature in the process range equal to ±1°C. The technical solution adopted by the manufacturer in this project is patented under the trademark Rollblock Plus for special internal geometry, and under the trademark Hydrogap for the hydraulic positioning system, which guarantees maximum thickness precision of the processing material.

The relationship with the customer has been further strengthened following a particular research and development contract to widen all the calender performance characteristics and applications, even with test sessions at Comerio Ercole R&D internal laboratory.
