That be illustratively mentioned in this as the prior art is 196 36 791 A1 of DE, existing in order to be better shown Technology, Fig. 1 are stored in figure 3 again in the application.In the Fig. 3, extrusion parts is marked with number 10 on the whole.Paper Web 64 is opened from the sieve 14 of the screen part 12 for being arranged in front guided via sieve deflector roll 16,18 by having suction branch The slewing rollers or pick-up roller 32 held lift, and are reached on upper felt 30 and squeeze gap 34.Upper felt 30 leave squeeze gap 34 it It is channeled out upwards by felt deflector roll 40 afterwards.
In addition, lower felt 42 was guided extruding gap 34, which guides via felt deflector roll 44,46 and 48.In extrusion slot After gap 34, paper web 64 is relayed on dry net 58 by suction roll 60 and is transported to arrangement along the direction of arrow 62 In drying part below.
It should be understood that can also successively be provided with multiple extruding gaps depending on the design scheme of paper machine.
It is seen along web direction of travel, after squeezing gap 34 and in the pumping being transported to paper web 64 on dry net 58 After suction roll 60, it is provided on the inside of lower felt 42 on the whole with the equipment of 20 label of number.The equipment 20 is including form The blower device of bellows 22 is arranged in subsequent 46 front of felt deflector roll and the blowing opening 24 with slit-like, via Compressed air can be blown over lower felt 42 by blowing opening, to make paper web residue when paper machine starts or to occur It lifts from lower felt 42 in the case of web break and is exported in pulper 54 arranged below along the direction of arrow 28, such as By as the web discharge part instruction with 56 label of number.
Suction roll 60 is to pivot, and therefore can be pivoted on lower felt 42, to be supported paper using suction Web is opened to quote onto dry net 58.
During production run, suction roll 60 is therefore positioned at pivoting in the positioning on lower felt 42, to make paper web It is transferred directly on dry net 58.
However it has been verified that although the equipment of 196 36 791 A1 of DE operates well, it some times happens that Web is not always broken by regulation or is passed through drum when being changing on dry net (referred to herein as " the second stretching ") Wind apparatus detaches.This means that the set width in pulper should be displaced on the first web travel path originally Material discharge part is drawn in the second web travel path upwards together again, and causes to go wrong herein.It may shape At paper waste material or the thickened section of bigger, this leads to web break.
Invention content
The task of the present invention is:So that more web is reliably transferred to the second width by function from the first web travel path Material travel path.
In the equipment aspect being previously mentioned, this task is solved in the following way, that is, is being constructed on web direction of travel To be disposed with web resolution element after the slewing rollers of suction roll.
The web resolution element causes for example to make towards pulping in the case where activation is configured to the slewing rollers of suction roll The high web of being pulled again that the direction of machine is located on the first web travel path is detached and is not carried to the second width On material travel path.It has been verified that web can be as follows in the transformation of web travel path from the first to the second Ground moves, that is, web export is forced to detach there by resolution element guiding and web.It is new width caused by this The only very short end at material beginning is changing on the second web travel path with being folded when necessary.But this is very short Bending part does not adversely affect transmitting function.
In order to so that maximum web bending length is kept as small as possible and advantageously, resolution element is on the first web traveling road 200mm is between 600mm after being arranged in suction roll on the web direction of travel of diameter.
Therefore, half-way house is had found, one side provides the sufficient space for pivoting suction roll, and another party Face keeps as short as possible for the web end of the separation of the second web travel path or new web beginning.
Advantageously, resolution element is formed by blade.
Blade occupies minimum space herein, and is dog-cheap component.After being placed on correct position, Blade even need not all be moved when cutting web.Blade can assemble securely, this is because web is in the steering procedure phase Between by blade guide and cut.Here, blade can have smooth or jagged cutting blade.In many cases Show bending or inclined cutting blade can also be meaningful, this is because its width is up to 10 meters of wide steerings Web is cut at first point first in this way, and cutting can then continue to extend to edge without a doubt.
Preferably, 15mm is divided between blade and the first stretching to 40mm.(wherein, the web in the operation phase of papermaking For example it is directed into pulper via the first web travel path due to starting or web break) there is no webs to be snarled Risk, this is because the interval of itself and blade is sufficiently large.It is advantageously provided herein, blade perpendicular to stretching cloth It sets, therefore following region will not be formed, have paper scrap accumulation in that region.In addition, blade is basic in cutting On perpendicular to web.
Particularly advantageously, the holder for being equipped with blade thereon includes splashproof wall.
Therefore, the holder of blade assumes responsibility for the second function and prevents from being splashed to and making from moist web or moist felt On other components of paper machine.
Preferably, blade is assemblied in a manner of it can replace on holder.
Each cutting blade of blade can finally be worn.In order to simplify the replacement to blade, blade is with the easily disassembled side of energy Formula is placed on holder.Here, connecting element should be touched from the edge of paper machine as far as possible, to keep personnel as simple as possible It is replaced on ground.
In terms of method, which is solved in the following way using the feature of claim 6:It carries out as follows It turns to, that is, web is made to contact with resolution element and be separated by the resolution element.
Therefore, the web advanced on the first web travel path is changing to by the slewing rollers for being configured to suction roll On two web travel paths.The web section for example to have advanced towards the direction of pulper on the first web travel path is again It is secondary to be raised, and preferably cut on entire web width by its contact with resolution element.Should have and create The way of property is unusual simple.
It is sufficient that as illustrated in the device claim, in the method, resolution element preferably passes through Simply, preferably fixed blade configuration.
In the method, when web must be drawn out in pulper downwards, the web is preferably in the first paper web row It is guided on inbound path.When web must be only imported into and be cut, or when web is broken before metastasis site, It is then such case.It will not be gathered in paper machine unit to be up to the web of 2000 ms/min of speed follower as a result, and And it need not again be removed in a manner of troublesome.
During the production process of paper machine unit, web usually turns upwards towards and via the second web travel path into one Step guiding.
