Definitions
- the invention relates to a defined as in the preamble of claim 1 press for a machine for producing a fibrous web such as in particular a paper, cardboard or pulp web.
- a press of the type mentioned above is known for example from DE 10 201 1 082 161 A1.
- the press described there comprises at least one press nip and two band-shaped coverings in the form of an underfelt and an upper felt.
- the at least one press nip is formed between a press roll and a counter press roll of the press for dewatering passing the fibrous web.
- the underfelt and the top felt are each guided by a plurality of guide rollers to the endless circulation, so that they run together through the press nip to pass the fibrous web sandwiched between received through the press nip.
- the underfelt and the top felt are separated again at a separation point in order to continue the fibrous web on the underfelt and to separate it from the top felt.
- An arranged at the separation point guide roller of the plurality of guide rollers is an evacuated guide roller of the lower felt and serves u.a. to keep the fibrous web at the separation point on the underfelt.
- Such an evacuated guide roll is also referred to as Saugfilzleitwalze.
- Saugfilzleitwalzen are used in particular above web speeds of 1 100 m / min to 1200 m / min, since the separation of the web as described above with a cheaper vacuum cleaner is no longer possible. Saugfilzleitwalzen offer the advantage of a very safe web separation up to high speeds, but are very expensive in terms of investment costs, spare parts and operating costs.
- a conventional Saugfilzleitwalze is usually carried out in two or more zonig, which is why a relatively expensive suction head is necessary for the extraction.
- a conventional Saugfilzleitwalze also requires a rotary drive, as they friction tet is and consumes even drive power in the felt loop. The drive also prevents the felt tension from falling too much directly after the press nip, which can otherwise lead to web disturbances.
- the rotary drive of the Saugfilzleitwalze is provided together with the suction on a drive side of the press, the rotary actuator must be performed usually eccentrically with a gear. Alternatively, the rotary drive can be performed centric on the drive side, but then usually the suction is expensive to move to a leader page of the press.
- the resulting web overstretch can then lead to significant wrinkling after the press and tearing in a subsequent pre-dryer section of the machine for making the fibrous web. Overall, the web running safety is impaired thereby.
- DE 10 201 1 082 161 A1 press is trying to increase the web security in the area before a pressing step by a standing support element on a web-facing side of the top felt is in contact with this, so that an approximately convex for the fibrous web curved web path results.
- this can necessitate additional web travel and thus increased production costs, which is anyway present in the press known from DE 10 201 1 082 161 A1 by the provision of a steam blower box arranged on a web-facing side of the top felt.
- the invention has for its object to provide a press as defined in the preamble of claim 1 for a machine for producing a fibrous web, so that with little effort an increased web security can be achieved by the cooperating with the two clothing press nip.
- a press for a machine for producing a fibrous web in particular a paper, board or pulp web, comprises at least one press nip formed between a press roll and a counterpressure roll of the press for dewatering passing the fibrous web, and two band-shaped clothing, which are each guided by a plurality of guide rollers to the endless circulation.
- the two fabrics are guided so that they pass together through the press nip to pass the fibrous web sandwiched therebetween through the press nip.
- the two fabrics are separated again at a separation point to continue the fibrous web on one string and to separate from the other stringing.
- a arranged at the separation point guide roller of the plurality of guide rollers is an evacuated guide roller of a stringing to keep the fibrous web at the separation point on the one string.
- the press according to the invention is characterized in that one of the evacuated guide roller in the endless circulation of a string immediately following guide roller of the plurality of guide rollers of a fabric is provided with a rotary drive.
- the guide roller immediately following the evacuated guide roller has a central drive pin. Due to the fact that the guide roller immediately following the evacuated guide roller has a rotary drive, the tension of the fibrous web continuing after the separation point can be stretched over a much greater web travel distance after the press nip, as special until after a web picking by a Abdgingsaugwalze a subsequent processing stage such as a pressing stage, maintained.
- the rotary drive of the guide roller immediately following the evacuated guide roller is designed for basis weights of the fibrous web of 25 g / m 2 to 500 g / m 2 .
