Abstract

The invention relates to a sheet-forming system (1) for a machine (2) for producing an at least single-layer fibrous material web (3), in particular a paper, cardboard or packaging paper web, from at least one fibrous material suspension (4; 4.1, 4.2). The system comprises at least one single-layer headbox (5) and a twin wire former (6), which comprises two endless wires (7, 8), each revolving in a wire loop (7.1, 8.1). The first wire is a Fourdrinier wire (7), which, in a pre-dewatering section (9) downstream [or in the region] of the application of the at least one fibrous material suspension (4; 4.1, 4.2) in the form of a free fibrous material suspension jet (4.S) by means of the at least single-layer headbox (5), is guided over a wire table (10) that is stationary and preferably under suction, the surface (11) of which touching the Fourdrinier wire (7) is formed by a covering (12) having a plurality of foils (13) which are arranged in succession in the wire running direction (S) and extend in the transverse machine direction (CD) and have interposed free dewatering openings (14), and over a plurality of suction elements (15), in particular suction boxes (15.1). The second wire is a top wire (8), and the two wires (7, 8) together form, at least in sections, a twin wire zone (16) having a wedge-shaped infeed nip (17). In the twin wire zone (16), the top wire (8) guided over an infeed roller (18) runs over a plurality of rigidly arranged foils (19), which are arranged spaced with respect to each other at a dewatering box (20). The sheet-forming system (1) according to the invention is characterised in that the covering (12) of the stationary wire table (10) that is preferably under suction comprises at least two zones (10.Z1, 10.Z2), each having a plurality of foils (13), wherein the foils (13) arranged in the first zone (10.Z1) are arranged with an average spacing (10.Z1.TD) in the range between 20 and 70 mm, preferably between 20 and 40 mm, more particularly between 20 and 35 mm, and the foils (13) arranged in the second zone (10.Z2) are arranged with an average spacing (10.Z2.TD) in the range between 50 and 120 mm, preferably between 50 and 100 mm, more particularly between 50 and 80 mm.
