Definitions
- the invention relates to an arrangement for transfer a fibrous web or a strip thereof from a moist tape to an air permeable Belt, the belts at least in the transfer area together run, separate after the transfer area and the receiving, air-permeable Tape is sucked on the side facing away from the fibrous web, according to Preamble of claim 1.
- Such an arrangement is used in particular in machines for the production and / or finishing of fibrous webs, especially paper, cardboard or tissue webs.
- the object of the invention is therefore to create an arrangement with the re-moistening while ensuring good web guidance the fibrous web is at least reduced.
- this is suitable a device with at least one transverse to the fibrous web and across the width of the suction zone, at which the belt taking over is led past.
- the suction zone is between the transfer area and the separation area relocatable, preferably swiveling. This enables the location to be adjusted the suction zone to the respective operating state in accordance with the above Method.
- the device has at least two separately controllable and also has suction zones extending transversely to the fibrous web.
- a suction zone is assigned to the transfer area and the separation area.
- the suction zones are also controlled in accordance with the claimed method.
- the transfer area After as a result of the widening strip through the entire fibrous web the transfer area is running, can be changed to the normal operating state. This means that the separation area is now at least predominantly vacuumed becomes. Since the entire fibrous web has greater stability, the suction can can be reduced or even discontinued in the transfer area. This saves not only energy but also reduces rewetting of the fibrous web in the Transfer area from the wet dispensing belt. Suctioning the takeover Band in the separation area, i.e. where the issuing tape has no contact has more with the fibrous web is sufficient for good web guidance.
- the receiving belt when transferring the entire fibrous web on the Side facing away from the fibrous web is preferably blown with air.
- the pressure the blowing should, however, only have a relatively low height.
- a third possibility, which can also be combined with the above-mentioned devices is that the taking over band over at least one across the fibrous web extending suction zone and the run of the dispensing belt is changeable in a form shifting the position of the transfer area.
- the transfer area depending on the operating state in the area the suction zone or in front of it in the direction of web travel.
- the suction zone of the transfer area should be connectable to a compressed air source.
- the suction zone of the transfer area does not have to cover the entire area Width of the fibrous web extend as it is only the transfer of a strip of it should support.
- the fibrous web 1 or a strip 2 thereof is covered by transfer a moist belt 3 to an air-permeable belt 4, the belts 3, 4 run together at least in the transfer area 5, after the transfer area 5 separate and that the overlying, air-permeable tape 4 on the fibrous web 1 or the strip 2 facing away is sucked.
- This transfer can, for example, in the former, in the dryer section, in the press section or can be realized in between, the bands 3, 4 being air-permeable and have the shape of felt or sieve.
- the dispensing tape 3 can also airtight in the form of a smooth press belt.
- the suction zones 7, 9, 10, 11 generally extend transversely to the fibrous web 1 and if necessary also across their entire width.
- FIG. 1A shows a suction roll 12 with a suction zone 7 for this purpose.
- This suction zone 7 is when transferring a strip 2 of the fibrous web 1 in the transfer area 5 and partially arranged in the separation area 6.
- the suction zone 7 according to FIG. 1B is turned the corresponding suction chamber in the suction roller 12 to the separation area 6 rotated. In this position, the transfer of the entire fibrous web 1 can be reduced Rewet the fibrous web 1 from the dispensing belt 3.
- FIG. 2A / B shows a similar possibility, but with the takeover band 4 runs directly over the suction zones 7 and the sealing at the edges via sliding surfaces 13 takes place.
- the device with the sliding surfaces 13 and the suction zone 7 becomes corresponding in this case pivoted.
- the suction roller 12 has three separately controllable Suction zones 9, 10 11, of which the suction zone 9 is assigned to the transfer area 5 is and is mainly activated only when a strip 2 is transferred, the suction zone 10 vacuumed the separation area 6 and mainly only when a fibrous web is transferred 1 works and the suction zone 11 the receiving belt 4 in front of the transfer area 5 sucked.
- the latter prevents the take-over of the air test layer Band 4 in the wrapping area of the fibrous web 1, so that a Transfer of the fibrous web 1 to this belt is possible faster.
