SA~KGROt3~i"D OF THE X~ENTION
~.. Field of, the invention.
The present invention relates to a water jet cutter ~oz separation of a trim sixip from a moving paper, cardboard, tissue ox other type of fiber web, in a machine for the pzoduction and/or con~~ersaon of the l~ber web, including at least one xxoz2le whose water jet is directed onto th,e fiber web.
Z. Description of the reiated art.
Because of the high pressure of the water jet and the assurartee of a clean cut while avai~ang tears or web breaks, the fiber web is supported on the opposite side when cutting by way of a water jet. This support is generally prot~aded by a cutting table.
Doting operation contarn,ination of flare suppoxt surfaces, causEd by the fibers or the additives i,» the fiber web occurs. In addition, the high pr~essute of the water jet over, a period of tinn,e leads to wear a>ad tear of the surfaces that are impacted by the vwater jet.
The cutting table, th,ereforc~, is often quipped with an opening opposite the water jet, for extraction and removal of the contaminants and tla~e water. Tie separated strip is sucked into a dischatge hoppear, with the assistance of vacuum. This is particularly oostly with regard to keeping the cutting tal3le clean and °w~ith regard to discharging the strip.
What is needed in the art is to simplify the eoz~,struction o~the cutter and provide at least equal operational reliability.
~U11~1NARY OF TH'C ~x~V'E1WT~ON
The pacesent invention provides a water jet cutter located approxirraatelf above a pulper, for the purpose of capturing the trim strip tbat is separated froz>n the ~.'ber t~reb, in this position in 2S the paper machine, the cutter does not require any discharge andlor vacuum systems. The z V~I02G3,US
G~~rGnszve cmr~.ng tatsle may therefore be reduced to a support plate. The support plate i's of extremely simple eonstruictioz~ and during cutting assures sufficient support of the f her vieb in the cutting area. The support plate is equipped with a cutout for the water jet, so that it can pass through unimpeded.
Afar the gutting point the separated trim falls ~~'the support plate. after the support plate the flow of the sEparated. trim, can be influenced by a guide device, preferably in the form of a guide plate andlor a guide component of the guide plate andlor a compressed air nozzle andJor a water jet nozzle. In order to prevent damage to the fiber rveb and to counteract contaminant accumulation,, the support plate can provide a sliding surface that as as flat as possible and that progresses approximately parallel to tlae fiber web.
To achieve perfect cutting quality and a stable cutting process the fiber web cari mn at a distance along the support plate, at least when uncornpromised by the water jet. Because of the flat and preferably smooth sliding sutfaoe, sliding of the fiber web durxt~g cutting does not present any negative effects. It has been shown to be advantageous if the distance befiween tt~.e fiber web and ~e sliding surface of the support plate, particularly when uncornpromised, i.s in the range of D to 2 rntn, preferably between 0 anal 0.5 mrn,.
The waste and pieces o,'~ the f bet web are collected in, the pulpex and the .fiber stock pz~eparation in order to be reutilized. Since the guide device supports the transportation of the separated trim into the pulper, expensive suction, devices for goading the separated trim can be E
avoided.
In order to adapt to certain operational conditions, the nozzle andlor the support plate and/or the guiding device can be adjustable relative to their Iocati,on.
Because of the already improved conszstency the water jet cutter can be located in the unsupported secti.aa. of the .ftber ~J'C7Ia263 _~'J'S
wen, m tt~e area of the dryer section. ~ its unsupported state, the fiber web runs wi.~kb.out being supported on a belt, a roll or a similar device.
The installation location is particularly easily realized based on the pulper location at the end of, a dryer group, preferably after the last dryer cylinder of the dzyer group, wbi.ch ~s the reason why the water jet cutter preferably is installed there. After leading aff of tb,e dryer fabric of the dryer group, the water jet cutter can be located advantageously between one, specifically the last dryer cylinder in th.e dryer group and a subsequent guide roller.

Itefezxing now to the drawings, and more paYticitlarly to Fig. 1, there is shown. a dryer section or group 20 of a paper machine wherein fiber web 1 tuns usually alternates over heated dryer cylinders 4 and suction equipped guide rowers I 3 for the purpose of being dried. Fiber web volo~~3.us t zs tamed by at least orxe dryer fabric 8 of the respective dryer group, whereby f ber v6reb 1 corner into contact with dryer cylinders 4.
T3uring drying the moisture content of fiber web 1 decreases and the consistency increases. In. order to produce clean edges ova fiber web l, the water jet cutter is utilized.
Because of the increased consistency of fiber web 1 this can occur in the:
unsupported section 22 of fiber ~ueb 1.
Tbis is relat~.vely easy at the ezad of one dryer group, and specifically as shown in Fig. 1, at the end of the last dryer group. After Ieadiz~g off the corresponding dryer fabric 8, fiber web 1 tra~rels into the area of water jet cutter 2~.. This is located between. dryer cylinder 4 and a IO subsequextt guide roller 5. Vdater jet cutter 2~4 includes essentially a nozzle 2 that is located above fiber web 1 and tbat directs the water jet approxixr~ately vertically onto fiber web I.
Suppozt plate 3 is located on the opposite side fox the purpose of supporting fzber web 1.
Support plate 3 is equipped with a flat and smooth surface and, iz~
uncompromise~d condition, is located at a distance 26 of between approximately 4 - 2 min, arad preferably 0.5 mm from ~,ber web I. During cutting however, fiber web 1 is pressed against support plate 3.
In order to avoid splash~back support plate 3 is equipped with cut-out a~ to accornna,odate the water jet accora~iz~,g to Fig. 2. In addition, support plate 3 includes guide component ltl that assists the further transportation of the separated trim into pulper ~ of the dryer section. Guide corr~ponent 10 eau, be adjustable relative to its location.
Since support plate 3 extends parali,el to the direction of travel of fiber web l, there is no possibility of fiber or other dirt accumulation.
After support plate 3, separated trim 7 is transported into pulper 6 that as located undezneatla 'eater jet cutter 24. Tlae collected fiber web pieces can then be zeutilized.
