    • The invention relates to a press section of a machine for producing a fibrous web (1), in particular a paper, cardboard or tissue web, having two press nips (3, 4) which lie behind one another in the web running direction (2) and are formed by in each case two press elements, wherein at least one separate, endlessly circulating press belt (5, 6, 7, 8) is guided around each press element in each case via a plurality of guide rollers (9), the fibrous web (1) runs together with two press belts (5, 6, 7, 8) which lie opposite one another in each case over a guide section (10, 11) downstream of the press nips (3, 4), and one belt (5, 7) is guided away from the fibrous web (1) downstream of the guide section (10, 11) which in each case follows a press nip (3, 4), whereas the opposite belt (6, 8) runs along a suction element (14, 15) together with the fibrous web (1). Here, secure web running is to be made possible with as little complexity as possible by virtue of the fact that the suction element (14) is formed by a rotating, evacuated guide roller downstream of the first press nip (3) and is formed by a stationary suction box downstream of the second press nip (4).

    • Die Erfindung betrifft eine Walze (100), nämlich Gautschwalze (100), für eine Formierpartie einer Einrichtung zur Herstellung einer Faserstoffbahn, insbesondere Papier- oder Kartonbahn, mit einer Längsachse (102) und einer im Wesentlichen zylindrischen Außenoberfläche (104), wobei die Außenoberfläche (104) wenigstens eine Rille (106, 108) umfasst, die sich im Wesentlichen schraubenförmig um die Längsachse (102) der Walze (100) erstreckt, wobei die Teilung (a) der im Wesentlichen schraubenförmigen Rille (106, 108) größer als 10mm, vorzugsweise größer als 12mm ist und wobei die Außenoberfläche (104) zwei Rillen (106, 108) umfasst, die sich jeweils im Wesentlichen schraubenförmig um die Längsachse (102) der Walze (100) erstrecken, wobei eine der beiden Rillen (106) von einer orthogonal zur Längsachse (102) orientierten Mittelebene (110) der Walze (100) ausgehend zu einem ersten Ende (112) der Längsachse (102) der Walze (100) verläuft und die andere der beiden Rillen (108) von der Mittelebene (110) ausgehend zu einem dem ersten Ende der Längsachse (102) gegenüberliegenden zweiten Ende (114) der Längsachse (102) der Walze (100) verläuft. Ferner betrifft die Erfindung eine Einrichtung mit einer solchen Walze (100).

    • The invention relates to a press (2) for a machine (1) for producing a fibrous material web (B), comprising: at least one press nip (N1, N2), formed between a press roller (10, 30) and a counter press roller (11, 31) of the press for guiding through the fibrous material web in a dehydrating manner, and two band-shaped covers (3, 4, 5, 6), which are each guided by multiple guide rollers (12-15, 16-21, 32-35, 36-40) in continuous circulation, so as to run together through the press nip, so that the fibrous material web is guided through sandwiched between said covers, and then separated again at a separation point (T1, T2), in order to continue guiding the fibrous material web on the one cover (3, 5) and separate it from the other cover (4, 6). One guide roller of the guide rollers arranged at the separation point is a suctioned guide roller (12, 32; 16') of the one cover (3, 5), to hold the fibrous material web on the one cover at the separation position. In order to achieve, with low output, an increased web movement security after the press nip cooperating with the two covers, a guide roller (13, 33) of the guide rollers of the one cover, directly following the suctioned guide roller in the continuous circulation of the one covering, is provided with a rotary drive.

    • The invention relates to a headbox (1) for a machine for producing a fibrous material web (3), in particular a paper, cardboard or tissue web (3), from at least one fibrous material suspension (2), comprising a feeding device (4, 5) feeding the at least one fibrous material suspension (2), a perforated distribution pipe plate (6), which is arranged immediately downstream of the feeding device (4, 5) in the flow direction (R) of the at least one fibrous material suspension (2) and which comprises a plurality of flow channels (7) arranged in rows (Z; Z.1 to Z.3) and columns (S; S.1 to S.4), an intermediate channel (8), which is arranged immediately downstream of the perforated distribution pipe plate (6) in the flow direction (R) of the at least one fibrous material suspension (2) and which extends in the width direction (B) of the headbox (1) and comprises two walls (9.1, 9.2) preferably having the width of the machine, a turbulence generating means (10), which is arranged immediately downstream of the intermediate channel (8) in the flow direction (R) of the at least one fibrous material suspension (2) and which has a plurality of flow channels (11) arranged in rows (Z; Z.1 to Z.3) and in columns (S; S.1 to S.4), and a headbox nozzle (13), which is arranged immediately downstream of the turbulence generating means (10) in the flow direction (R) of the at least one fibrous material suspension (2) and which has a nozzle gap (14), wherein the feeding device (4, 5), the perforated distribution pipe plate (6) and the intermediate channel (8) are arranged in a first alignment plane (AE.1), and the turbulence generating means (10) and the headbox nozzle (13) are arranged in a second alignment plane (AE.2), and wherein the two alignment planes (AE.1, AE.2) form an angle (α) in the range of >90 and
