Abstract (en)
A multi-layer dewatering medium (30) having on its one side a first surface (33), which constitutes the forming surface of the medium, and on its opposite side a second surface (35). At least in the machine direction (31) the layer closest to the second surface (35) is made up of strands (36), said strands abutting in continuous or discontinuous lengths (floats) (37) on the second surface (35). The longest ones of said lengths (floats) (37) in the machine direction (31) are longer than discontinuous lengths (floats) (38, 39) of strands (34) which are repeated in the cross-machine direction and which abut on said second surface (35).
