Helsinki, Finland, 17 May 2011 -- Metso will rebuild the folding boxboard machine at the San Juan del Río mill of Cartones Ponderosa, S.A. de C.V. in Mexico. The start-up of the rebuilt machine is scheduled for the second quarter of 2012. The value of the order will not be disclosed. The order is included in Paper and Fiber Technology’s second quarter 2011 orders received.

Metso's delivery will include rebuilds of the coating and drying sections. Drying capacity will be increased with two impingement dryers, enabling a production and a speed increase. Replacing the coating station with a curtain coater and a new coating color supply system will further improve the folding boxboard quality.
