HERGEN modernizes PM#1 at São Gabriel Papéis

March 7, 2025

Papelera Nacional de Ecuador (PANASA) has installed a new Excel Rewinder, supplied by HERGEN, on its paper machine PM1. The acquisition of the new equipment has the following targets: to meet the increased production capacity of the paper machine, to replace the limitations of the old Rewinder, to improve the quality of the rewound reels, and to increase efficiency and safety in the process.

Project data

The new Rewinder has been designed to operate at a speed of up to 1,600 m/min, with the capacity to rewind corrugated medium and liner papers, with basis weight ranging from 120 to 270 g/m², with the following roll sizes:

• Jumbo rolls: Ø 2,200 mm x 2,400 mm

• Baby rolls: Ø 1,500 mm x 2,400 mm

The slitting section is equipped with 6 knives and the minimum slith width is 80 mm. The NIP control is hydraulic, guaranteeing greater precision and flexibility in the process.

Results

Shortly after start-up, the equipment has successfully achieved the objectives set for the MP1 upgrade. The Rewinder continues to evolve, progressively adapting to the machine's requirements, while continuous improvements and productivity increases are consistently implemented, highlighting the excellent runnability of HERGEN's Excel line Rewinders.

HERGEN/PANASA partnership

In recent years, PANASA has invested in continuous improvements to its PM1 and PM2 machines. For HERGEN, it has been a great pleasure to establish a long-lasting and trusting partnership with PANASA, achieving success in important projects such as the implementation of new Fabricated Drying Cylinders, new fabric Guide Rolls and new Pope Reels for both, PM1 and PM2.

The installation of the new Rewinder at PM1 is another significant milestone in this successful partnership, aligned with PANASA's growth and innovation objectives.
