Abstract
A sheet forming screen is described which is formed as a multi-layer fabric, wherein the fabric has a longitudinal thread repeat of sixteen longitudinal threads, four longitudinal threads (to) of which are formed as upper longitudinal threads, eight longitudinal threads (to) of which are formed as lower longitudinal threads, and the remaining four longitudinal threads (to) of which form two functional longitudinal thread pairs of two longitudinal threads each arranged next to each other which alternately complete the first weave, wherein at least one of the four longitudinal threads which form the two functional longitudinal thread pairs extends both in the upper fabric layer and in the lower fabric layer and thereby binds the lower fabric layer to the upper fabric layer.
