Apr 24, 2012. /Lesprom Network/. Papelera del Sur S.A., part of Cartones America Group, has successfully started up its PM5 at Chincha, Peru, after a drying section upgrade carried out by the Italian company Toscotec. The PM5 produces white top test liner, brown test liner, medium and fluting starting from recycled paper, as the company said in a press release received by Lesprom Network. The project aim was to increase production and to optimize the efficiency of the paper machine. This has been achieved by adding new dryers at the end of the existing drying section, eliminating the rope tail threading system from the last two batteries and installing a new air blow threading system. Toscotec scope of supply consisted of a new complete double tier drying battery with 6 TT SD (Toscotec's signature steel dryer cylinders) 2000 mm diameter, 10 bar coded. The installation of TT SD 2000 mm diameter allows to get a large drying surface with a smaller number of dryers and related accessories (such as wire rolls, doctors, in-drive points, etc) if compared to the installation of standard 1500 mm diameter dryers. This results in a lower investment cost but also in energy saving. Cartones America is a leading, privately-owned, Andean Region manufacturer of containerboard, corrugated boxes, clay-coated paperboard, spiral tube board and specialty board packaging products. Toscotec is a leading company in the design, manufacturing and delivery of complete plants and equipment for the production of tissue, paper and board.
