In the press section of a paper machine, water is mechanically removed from the newly formed sheet. In the simplest press, the sheet is carried by a press fabric between two rolls, where water is removed with the application of load and pressure. This can also be assisted by the use of vacuum and heat. Press fabrics can last normally from 1 to 6 months. Albany International’s innovative products such as seamed, Non-Woven and coated materials provide consistent, class leading performance for our customers.
Hydrocross significantly reduces installation time, increases energy savings, and reduces risk
