Propasa Starts-up Rebuilt Linerboard Machine in Mexico

Aug. 12, 2013 (Press Release) - Mexican board producer Propasa aimed to increase production by up to 25% to manufacture nearly 500 metric tons of board per day, as well as to improve the final quality of its product, so it chose Voith to rebuild its PM 3.

The project's first part included the supply of a MasterJet Pro F/B headbox with ModuleJet II dilution control as well as the rebuild of the forming section including a DuoShake that allows for greater homogeneity in the paper web formation. Furthermore, the reel and winder were modernized. In a second step, the dryer section was rebuilt.

Propasa also utilized Voith’s basic engineering services for the steam and condensate, lubrication, ventilation and vacuum systems.

Shortly after start-up, the machine was producing saleable paper and there was a visible improvement in product quality. With this outcome, the company has taken an important step towards consolidating the group's growth in highly competitive markets such as Mexico and the USA.

The project's second phase was completed in July 2013 when two dryer sections were added to the machine, thereby increasing the machine's speed.
