Abstract

The screen (1) has longitudinal threads (4, 5) divided in the ratio of number of threads in a longitudinal thread layer (3) on a machine side and a thread layer (2) on a paper side. Binding cross threads (10, 11) are bound in the thread layers (2, 3). Fiber support index (FSI) of the screen ranges between 230 to 250, and rectangular shaped flow-through openings are formed on the paper side. Diameter of the threads in the longitudinal thread layer on the machine side ranges between 0.15 to 0.25 millimeter. A part of the threads consists of polyethylene terephthalate (PET) material. Air permeability of the screen ranges between 5700 to 10600 meter cube or meter square/hour. The total fill degree of the longitudinal threads is 85 percent.
