Definitions
- the invention relates to a method for producing a fibrous web, in particular a paper or cardboard web, from at least one fiber suspension, with two revolving endless sieves (inner sieve, outer sieve), whereby the Inner sieve is guided over a peripheral region of a forming roll and that Outer sieve is guided over a circumferential area of a breast roll and then in the area of the forming roller onto the inner wire to form a wedge-shaped Inlet gap that is a pulp suspension directly from a headbox records, is guided and then a twin wire section through the two sieves (inner sieve, outer sieve) is formed, which runs out of the forming roller at an angle of -50 ° to + 50 ° to an imaginary one Vertical plane runs down and at the end of a deflection device, in particular a deflection roller is arranged, by means of which at least one of the two screens in a preferably essentially horizontal running direction be redirected.
- two revolving endless sieves inner sieve, outer sieve
- the invention further relates to a twin wire former of a machine for production a fibrous web, in particular a paper or cardboard web, according to the preamble of claim 6.
- twin wire former is for example from the German published application DE 198 03 591 A1 (PB10656 DE) of the applicant is known.
- the twin wire former shown comprises two continuous endless screens (inner wire, Outer sieve), of which the inner sieve over a circumferential region of a Forming roller runs and the outer wire over a peripheral region of a breast roller runs and then in the area of the forming roller onto the inner wire with formation a wedge-shaped headstock gap that comes directly from a headbox absorbs a fiber suspension, accumulates.
