Definitions
- the invention relates to a machine for Manufacture of a fibrous web, e.g. Paper web, with a running porous belt and a Suction box according to the Preamble of claim 1.
- a fibrous web e.g. Paper web
- a running porous belt and a Suction box according to the Preamble of claim 1.
- the suction box is used, for example, in a paper making machine for dewatering a paper web that is on a sieve belt or between two sieve belts is.
- the sieve belt or sieve belts run or run together with the paper web to be drained over the suction box, so that the negative pressure prevailing in the suction box leads to drainage the paper web causes.
- the suction box has at least two support strips, which with the Sieve belt (or with one of the two sieve belts) in contact come. There is a suction slot between every two support strips.
- the length of the suction slots (and thus the length of the suction zone) is determined by two sealing strips.
- at each end of the Suction box i.e. in the two edge zones of the sieve belt
- at least a part of these filler pieces can be adjusted transversely to the tape running direction, namely for the purpose Change the length of the suction zone.
- the fillers generally referred to as a "format pusher".
- the permeability of the filler extensions for fluid can be implemented in different ways: For example the extensions, seen from above, can be wedge-shaped train and / or you can perforate the extensions.
- Figure 1 shows a suction box in a cross section along the line I-I of Figure 2.
- FIG. 2 is a top view of the suction box according to FIG 1.
- the suction box designated overall by 10, essentially consists from a trough 11, from a few arranged transversely on it Support rods 13 and from support strips 20, which extend in the longitudinal direction of trough 11, i.e. transverse to the running direction P of the sieve belt 9 extend.
- the running sieve belt 9 comes with the heads the support bars in direct contact.
- Fasteners, with which the support strips 20 are attached to the support rods 13 are designated by 25, 26, 27. Between the ends of the Support rods 13, sealing strips 16 are provided.
- the width of the belt 9 is designated B. and the length of the remaining between the support strips 20 Suction slots with L; this is the so-called suction zone length. It is determined by fillers 31, 32, 33, which between the support strips 20 are fitted sealingly.
- Each of the fillers 31 to 33 has an extension 31 'to 33 'on. These extensions extend from End of the suction zone length L, towards the center of the machine out. Each of the filler pieces and the associated extensions come in just like the support strips 20 with the band 9 direct contact. However, the extensions are in the Top view according to Figure 2 seen, either tapered wedge-shaped (see 31 'or 32') or they are perforated (see 33 '). It is also possible, both a wedge-shaped taper to provide a perforation.
