Luohe Yinge Reports Success with Nipcoflex T Shoe Presses in Two Tissue Lines

Luohe Yinge Tissue Paper Co., China, reports that it is "completely satisfied" with the performance of Voith NipcoFlex T shoe presses recently installed in two of its tissue lines. "The shoe presses bring outstanding results," said QiFeng Wang, Vice GM at Luohe Yinge Tissue Paper. "We obtain a dry content after the press that is 5% higher than with conventional technologies. Thus we save 20% thermal energy in the dryer section."
 

The two identical lines Voith (Germany) delivered to Luohe Yinge produce tissue in a basis weight range of 12–30 gsm. The lines include the entire stock preparation, the wet end process, and the tissue machines, from the headbox to the reel.

ShiJin Zhang, GM at Yinge Tissue Paper, noted that "we can consolidate and expand our position in the Chinese market with the new machines. We are now in a position to meet the increasing requirements of our customers regarding quality and quantity and have thus achieved our aim."

The Voith tissue machines are designed for an operating speed of 1,900 m/min and an annual production of about 60,000 metric tons each, with a paper width of 5,550 mm on the reel section.

With the NipcoFlex T shoe press, Voith explains, up to 5% higher dryness can be achieved compared with a configuration of a suction roll pressed against the yankee or earlier shoe press generations, and this is possible without compromising paper quality. In addition, a production increase or energy savings up to 20% are feasible due to higher after-press dryness. The high flexibility of the press shoe allows tracing the yankee deflections more precisely and results in a more uniform cross directional dryness profile. Switching between bulk and dryness mode and vice versa is even possible during production, increasing the machine’s efficiency.

The NipcoFlex T shoe press has a much simpler construction than the first shoe press generation. The two rubber bellows pressing device, instead of several pistons along the machine width, results in fewer controls required and thus in simpler operation, Voith adds.

Luohe Yinge Tissue Paper Co. was founded 20 years ago in the province of Henan, China.
