Opfindelsen omhandler en fremgangsmåde til anbringelse af markeringslinier på en bindemiddelholdig mineralfiberbane og af den krav l's indledning angivne art.The invention relates to a method for applying marking lines to a binder-containing mineral fiber web and to the nature of the preamble of claim 1.
5 Fra tysk offentliggørelsesskrift nr. 32 29 601 er det kendt at indbrænde markeringslinier på overfladen af mineral fiberbaner ved hjælp af en skarpt opdelt flamme eller en skarpt opdelt varmluftstråle med en temperatur på eksempelvis 600 °C. Hertil skal der blot anbringes en 10 tilsvarende varmluftdyse eller flammefakkel over den forbipasserende mineralfiberbane.5 From German Publication No. 32 29 601 it is known to burn marking lines on the surface of mineral fiber webs by means of a sharply divided flame or a sharply divided hot air jet having a temperature of, for example, 600 ° C. To do this, simply place a corresponding hot air nozzle or flame torch over the passing mineral fiber web.
En sådan fremgangsmåde muliggør dog kun at anbringe med randen parallelle markeringslinier, idet vinkelret på 15 randene forløbende markeringslinier kræver en ikke stationær anbringelse af varmluftdysen, da denne skal kunne tværforskydes over mineralfiberbanen og dermed bevæges sammen med denne. Endvidere fremkalder en sådan flamme eller varmluftstråle ikke blot den ønskede opløsning af 20 bindemidlet på overfladen, men udøver også en ikke uvæsentlig dybdevirkning i et indre område, i hvilket intet bindemiddel er virksomt.However, such a method only allows parallel marking lines to be arranged with the rim, since perpendicular marking lines extending perpendicularly require a non-stationary application of the hot air nozzle, since it must be able to be displaced across the mineral fiber web and thus be moved together with it. Furthermore, such a flame or hot air jet not only produces the desired solution of the binder on the surface, but also exerts a not insignificant depth effect in an inner region in which no binder is effective.
Fra tysk offentliggørelsesskrift nr. 34 46 406 er det 25 kendt som opvarmningsindretning at anvende en valse. Denne tjener dog ikke til at anbringe markeringslinier, men til at fremkalde dybt i mineralfiberbanematerialet indtrængende hæftepunkter, som lokalt blødgør mineralfibrene og derved svejser disse indbyrdes sammen. Valseoverfladen 30 frembyder hertil en række åbninger, gennem hvilke der udstråler varmgas med en høj temperatur, som regel op til 1000 °C.From German Publication No. 34 46 406 25 it is known as a heating device to use a roller. However, this does not serve to place marking lines, but to induce penetration points deep in the mineral fiber web which locally soften the mineral fibers and thereby weld them together. To this end, the roller surface 30 provides a number of openings through which radiate hot gas at a high temperature, usually up to 1000 ° C.
En sådan indretning er ikke egnet til frembringelse af 35 markeringslinier, fordi den praktisk talt ikke øver indflydelse på mineralfibermaterialets adfærd på markeringsstedet. Der opstår også i randområderne en kun delvis op- 2Such a device is not suitable for producing 35 marking lines because it practically does not affect the behavior of the mineral fiber material at the marking site. There is also only a partial rise in the peripheral areas

løsning af bindemidlet, der fører til en uskarp afgrænsning af markeringen.solution of the binder leading to a blurry demarcation of the selection.
Opfindelsen har til formål, ud fra den fra ovennævnte 5 tyske offentliggørelsesskrift nr. 32 29 601 kendte teknik, at tilvejebringe en fremgangsmåde, hvorved der på meget simpel og driftssikker måde kan anbringes på tværs af siderandene forløbende markeringslinier på en mineral-fiberbaneoverflade og en lille indtrængningsdybde af op-10 løsningsprocesserne en anbringelse af rent afgrænsede markeringslinier i indbyrdes nøjagtige og uforanderlige afstande.The invention has for its object, from the prior art German Patent Specification No. 32 29 601, to provide a method whereby, in very simple and reliable way, transverse marking lines can be placed on a mineral fiber web surface and a small penetration depth of the solution processes a placement of purely delimited marking lines at mutually accurate and unchanging distances.
Dette opnås ifølge opfindelsen for en fremgangsmåde af 15 den indledningsvis angivne art, der er kendetegnet ved de i krav 1's kendetegnende del angivne arbej dstrin.This is achieved according to the invention for a method of the kind specified in the introduction, characterized by the working steps according to the characterizing part of claim 1.
Som følge af indgrebsforholdene mellem valsen og mineral-fiberbaneoverfladen kan der optræde en ringe afvigelse i 20 linieafstanden, som dog i praksis er meget ringe, for en værdi på 20 x 100 mm = 2 m eksempelvis 1,96 m. For at udelukke også sådanne små afvigelser kan valsen drives med en periferihastighed, der afviger en smule fra mineralf iberbanens fremføringshastighed.Due to the engagement relationship between the roller and the mineral fiber web surface, a slight deviation can occur in the 20 line spacing, which is, however, in practice very small, for a value of 20 x 100 mm = 2 m, for example 1.96 m. For small deviations, the roller can be operated at a peripheral speed which differs slightly from the feed rate of the mineral fiber.

Da energiafgivelsen fra de opvarmede zoner er indskrænket til det, der kræves til at opløse bindemidlet over et rent afgrænset lokalt område og kun i en ringe overfladedybde, er energiforbruget minimalt.As the energy release from the heated zones is limited to what is required to dissolve the binder over a purely defined local area and only at a low surface depth, energy consumption is minimal.

Ved den i krav 2 angivne fremgangsmåde sker der en forbedring af varmeledningen fra opvarmningszonen til mineralfibrene, og der opnås en forlængelse af anlægstiden mellem opvarmningszonen og mineralfibrene og dermed også 35 en forbedring af varmetransmissionen, uden at temperaturen i opvarmningszonen kommer til at forlade et optimalt driftsområde.In the method of claim 2, an improvement of the heat conduction from the heating zone to the mineral fibers is achieved and an extension of the contact time between the heating zone and the mineral fibers is achieved and thus also an improvement of the heat transmission without leaving the temperature in the heating zone to an optimal operating range. .

Ved den i krav 3 angivne fremgangsmåde bortfalder midler til variering af vægtunderstøtningen under drift, og valsens virksomme vægt kan efter behov tareres ved modvægt 5 til en ønsket formindsket værdi.In the method of claim 3, means for varying the weight support during operation expire, and the effective weight of the roll can, if necessary, be counterbalanced at counterweight 5 to a desired reduced value.
Ved denne i krav 4 angivne fremgangsmåde bortfalder en særskilt tandhjulsudveksling til drift af valsen, idet denne kan nøjes med en simpel tandhjulsudveksling til i 10 udtrukket hvilestilling at tilvejebringe en ensartet opvarmning af de langs valsens periferi fordelte opvarmningszoner.In the method set out in claim 4, a separate gear exchange for operation of the roller lapses, which can be satisfied with a simple gear exchange to provide uniform heating of the heating zones distributed along the periphery of the roll in extended resting position.
Ved den i krav 5 angivne fremgangsmåde kan man arbejde 15 med enkelte kortere, i indbyrdes afstand beliggende opvarmningszoner, og energiforbruget formindskes.In the method according to claim 5, one can work with a few shorter, spaced heating zones, and the energy consumption is reduced.
Opfindelsen omfatter også et til udøvelse af opfindelsen egnet apparat, der er ejendommeligt ved den i krav 6's 20 kendetegnende del angivne konstruktion.The invention also includes an apparatus suitable for the practice of the invention which is peculiar to the construction of the characterizing part of claim 6.
Ved det i krav 7 angivne apparat opnås en minimering af energitabet ved varmestråling eller varmeledning fra opvarmningsstavene og en ren afgrænsning af opvarmningszo-25 nerne og renere markeringslinier.By the apparatus of claim 7, a minimization of the energy loss by heat radiation or heat conduction is obtained from the heating rods and a clean demarcation of the heating zones and cleaner marking lines.
Ved det i krav 8 angivne apparat opnås, at den luft, der omgiver opvarmningsstavene, bevirker en afkøling af det op til markeringsstriberne tilgrænsende mineralfibermate-30 riale og dermed også renere markeringslinierande.By the apparatus of claim 8, it is obtained that the air surrounding the heating rods causes a cooling of the mineral fiber material adjacent to the marking strips and thus also cleaner marking line edges.
Ved det i krav 9 angivne apparat opnås en konstruktionsmæssig frihed for udformningen af opvarmningsstavene.By the apparatus of claim 9, a structural freedom is obtained for the design of the heating rods.
35 Ved det i krav 10 angivne apparat opnås, at hver af polygonens plane sideflader på simpel måde kan virke som bærer for holderen og indbygningen af en opvarmningsstav.The apparatus of claim 10 provides that each of the plane side faces of the polygon can act simply as a carrier for the holder and the incorporation of a heating rod.

Ved det i krav 11 angivne apparat opnås på simpel måde en synkronisering mellem valsens driftsomløbshastighed og transportbåndets fremføringshastighed, idet opvarmnings-5 fasen kan ske ved en kontinuerlig langsom omdrejning af valsen med et ukritisk omløbstal til at opnå en jævn opvarmning af opvarmningsstavene, og motorens friløb muliggør et motoreftersyn, så snart valsen ligger an imod mineralfiberbanen og drives af denne med en forøget om-10 løbshastighed. Ved hver driftsforstyrrelse drejer elektromotoren derefter den optrukne valse igen for at tilvejebringe en stadig jævn opvarmning af opvarmningsstavene.In the apparatus of claim 11, a simple synchronization is obtained between the operating speed of the roller and the conveying speed of the conveyor belt, the heating phase being able to take place by a continuous slow rotation of the roller with an uncritical circulation number to obtain a uniform heating of the heating rods, and the engine run-off. enables a motor overhaul as soon as the roller abuts against the mineral fiber web and is driven by it at an increased speed of about 10. With each malfunction, the electric motor then turns the retracted roller again to provide a still uniform heating of the heating rods.
Ved det i krav 12 angivne apparat opnås til enhver tid en 15 finjustering af valsens indtrykningsforhold på mineralfi-berbanen.By the apparatus of claim 12, a fine adjustment of the roller's compression ratio on the mineral fiber web is obtained at all times.
Ved det i krav 13 angivne apparat opnås en problemfri. fjernstyret finjustering og opretholdelse af denne, og 20 ved det i krav 14 angivne apparat opnås en hurtig fjernstyret kobling af valsen mellem en nedsænket driftsstilling og en optrukket hvilestilling, mens finjusteringen sker ved hjælp af justeringsdrevet, hvis stilling ikke må ændres under driftspauser eller andre driftsafbrydelser.The apparatus according to claim 13 results in a trouble free. remote control fine adjustment and maintenance thereof, and 20 in the apparatus of claim 14, a quick remote controlled coupling of the roller between a submerged operating position and a retracted rest position is achieved, while the fine adjustment is done by the adjustment drive, the position of which must not be changed during breaks or other interruptions. .

Fig. 1 viser den venstre ende af en valse 1 med tilhørende lejekomponenter. Valsen 1 er lejret på samme måde ved sin højre ende. En aksel 2 er forbundet med valsen 1 og 5 tjener til lejring af valsen på en lejeramme 3 via tosidige lejer 4. Uden for lejerne 4 rager akselen 2 ind i en elektrisk tilslutningsboks 5, hvor der på konventionel måde via slæberinge 6 tilvejebringes en strømforsyning til valsens drejende dele.FIG. 1 shows the left end of a roller 1 with associated bearing components. The roller 1 is mounted in the same way at its right end. A shaft 2 is connected to the roller 1 and 5 serves for storing the roller on a bearing frame 3 via two-sided bearings 4. Outside of the bearings 4, the shaft 2 projects into an electrical connection box 5, where a power supply for the rotating parts of the roller.

Rammen 3 kan bevæges op og ned på søjler 10 i en stationær portal 11. På samme måde kan en holderamme 12 med en travers 13 bevæges op og ned langs søjlerne 10. Rammen 3 holdes på holderammen 12 via et trykorgan 14, eksempelvis 20 i form af en pneumatisk cylinder 15, der er lejret på traversen 13, og hvis stempelstænger 16 angriber rammen 3 ved 17. Ved fastholdt holderamme 12 vil en indtrækning af Stempelstangen 16 i cylinderen 15 således medføre en løftning af lejerammen 3 og valsen 1 til en optrukket 25 hvilestilling, hvorimod driftsstillingen som vist på fig.The frame 3 can be moved up and down on columns 10 in a stationary portal 11. Similarly, a holding frame 12 with a traverse 13 can be moved up and down along the columns 10. The frame 3 is held on the holding frame 12 via a pressure means 14, for example 20 in shape. of a pneumatic cylinder 15 which is mounted on the traverse 13 and whose piston rods 16 engage the frame 3 by 17. Thus, when the retaining frame 12 is retained, a retraction of the piston rod 16 in the cylinder 15 causes a lifting of the bearing frame 3 and the roller 1 to a pulled 25 resting position, whereas the operating position as shown in fig.
2 foreligger ved sænket stilling af lejerammen 3.2 is available when the bearing frame is lowered 3.
Holderammen 12 er på sin side via et justeringsdrev 18 forbundet med en travers 19 på den stationære portal 11.The retainer frame 12, in turn, is connected via an adjusting drive 18 to a traverse 19 on the stationary portal 11.
30 Justeringsdrevet 18, eksempelvis i form af en gevindspindel 20, drives via en elektromotor 21, eksempelvis i form af en skridtmotor, og en udveksling 22. Ved hjælp af justeringsdrevet 18 kan traversens 13 og holderammens 12 højdestilling finjusteres i en ønsket position. Ved ud-35 trukket stempelstang 16 i trykorganet 14 opnås herved en tilsvarende bestemt højdestilling for valsen 1.

5 Som vist på fig. 2 har valsen 1 et polygonformet bærelegeme 23, i det viste eksempel en 20-kant, på hvis plane omkredsflader 24 der fastholdes holdere 25 for opvarmningsstave 26 via skruer 27. Opvarmningsstavene 26 er udformet med i det indre af holderne 25 anbragte lejelege-10 mer 28 og med fra valsens 1 periferiske overflade 29 udragende markeringsribber 30. Opvarmningsstavene 26 består af et godt varmeledende metal og har i området for deres lejelegemer 28 eksempelvis runde udsparinger 31 til optagelse af konventionelle rørvarmelegemer 32, svarende til 15 dyppekogevarmeslanger. Til montering af røryarmelegemerne 32 er opvarmningsstavene 26 delt langs et i forhold til valsens 1 akse radialt plan 33 i to dele, 26a og 26b, der er forbundet med hinanden ved hjælp af undersænkede skruer 34 og 35. Efter indmonteringen af rørvarmelegemer-20 ne 32 i udsparingen 31 formonteres de åbne dele 26a og 26b ved indsætning af skruerne 34 og 35 og indskydes i holderne 25. Derefter forsynes holderne 25 på deres yderside med dækplader 36, der griber over skuldre 37 på hver varmestavs lejelegeme 28 og derved fastholder varmesta-25 vene 26 sikkert i holderen 25.5 As shown in FIG. 2, the roller 1 has a polygon-shaped support body 23, in the example shown, a 20 edge, on whose plane circumferential surfaces 24 retaining holders 25 for heating rods 26 via screws 27. The heating rods 26 are formed with bearing elements 10 arranged in the interior of the holders 25 28 and with marking ribs protruding from the peripheral surface 29 of the roller 1, the heating rods 26 consist of a good heat conducting metal and have in the area of their bearing bodies 28, for example, round recesses 31 for receiving conventional tube heating elements 32, corresponding to 15 dip boiler heat hoses. For mounting of the tube arm bodies 32, the heating rods 26 are divided along a radial plane 33 relative to the axis of the roller 1 into two parts, 26a and 26b, which are connected to each other by countersunk screws 34 and 35. After the mounting of the tube heater members 20 in the recess 31, the open parts 26a and 26b are pre-assembled by inserting the screws 34 and 35 and inserted into the holders 25. Thereafter, the holders 25 are provided on their outer side with cover plates 36 which grip over shoulders 37 on the bearing body 28 of each heating rod, thereby retaining the heat-25 vein 26 securely in holder 25.
Holderne 25 og dækpladerne 36 består af et dårligt varmeledende materiale, såsom et fiberholdigt sammenpresset materiale på basis af asbest eller asbestsubstitut, for 30 at undgå varmetab fra opvarmningsstavene 26 og for at beskytte periferiområderne af yderfladerne 29 på begge sider af markeringsribberne 30 imod opvarmning og varmeafgivelse til materialet af mineralfiberbanen 38. På denne måde er alle de inden for valsens 1 yderflade 29 liggende 35 varmestavsider omgivet af varmeisolerende materiale.The holders 25 and cover plates 36 consist of a poorly heat-conducting material, such as an asbestos or asbestos-substituted fiber-containing compressed material, 30 to avoid heat loss from the heating rods 26 and to protect the peripheral areas of the outer surfaces 29 on both sides of the marking ribs 30 from heating and heat release. to the material of the mineral fiber web 38. In this way, all the 35 hot rod sides lying within the outer surface 29 of the roller 1 are surrounded by heat insulating material.

af et jordforbindelseskabel. Derudover har mindst én af opvarmningsstavene 26 en udsparing 40 i nærheden af stavens markeringsribber 30 til optagelse af en termoføler. Rørvarmelegemernes 32 strømforsyning og temperaturregu-5 lering via termoføleren sker ved hjælp af slæberingene 6 (se fig. 1). Som følge af finstyringen for den optimale dannelse af markeringerne ved forskellige anlægstryk af valsen 1 på mineralfiberbanen 38 kan en særlig temperaturregulering ved hjælp af termoføler dog også bortfalde 10 og derved kun strømtilgangen til rørvarmelegemerne 32 reguleres. Ved stationær drift opstår der derved en bestemt temperatur, der er egnet til at frembringe markeringerne, hvor da den optimale udformning af markeringerne kan indstilles ved indtrykningsgraden for valsen 1 i mineralfi-15 berbanen 38. Som vist på fig. 3 strækker opvarmningsstavenes 26 markeringsribber 30 og i givet fald selve opvarmningsstavene sig kun langs en del af valsens 1 ak-siale længde, så at flere markeringsribber 30 danner en afbrudt linie langs en kappelinie på valsen 1 og holdes i 20 en aksial indbyrdes afstand. Ved denne begrænsning anvendes der et antal enkelte kortere opvarmningsstave med let regulerbare varmeudvidelser.of a grounding cable. In addition, at least one of the heating rods 26 has a recess 40 in the vicinity of the rods marking ribs 30 for accommodating a thermal sensor. The power supply and temperature control of the tube heaters 32 via the thermocouple are effected by means of the slip rings 6 (see Fig. 1). However, due to the fine control of the optimum formation of the markings at different abutment pressures of the roller 1 on the mineral fiber web 38, a special temperature control by means of a thermocouple can also be dispensed with 10 and thus only the power supply to the tube heating elements 32 can be controlled. In the case of stationary operation, there is thus a certain temperature suitable for producing the markings, whereby the optimum design of the markings can be set at the degree of pressure of the roller 1 in the mineral fiber web 38. As shown in FIG. 3, the marking ribs 30 of the heating rods 26 extend and, where appropriate, the heating rods only along a portion of the axial length of the roll 1, so that several marking ribs 30 form an interrupted line along a cutting line on the roll 1 and are kept at an axially spaced distance 20. This restriction uses a number of single shorter heating rods with easily adjustable heat extensions.
Den indbyrdes forbindelse mellem opvarmningsstavene 26 25 kan da ske ved hjælp af ledninger eller via et tilsvarende periferisk isolerende stykke af rørvarmelegemet 32, der forbinder opvarmningsstavene 26 i en slags bueform.The interconnection of the heating rods 26 25 can then be effected by means of wires or via a corresponding peripheral insulating piece of the tube heating element 32 connecting the heating rods 26 in a kind of arc shape.
Hvis derimod opvarmningsstavene 26 strækker sig over valsens 1 samlede aksiale længde, og der kun forefindes de 30 til afbrydelse af markeringen påkrævede huller, opnås der en meget robust og stabil konstruktion, hvor rørvarmelegemerne 32 er indlejret i opvarmningsstavene 26 langs hele deres længde.On the contrary, if the heating rods 26 extend over the total axial length of the roller 1 and only the holes required for breaking the mark are present, a very robust and stable construction is obtained, where the tube heating elements 32 are embedded in the heating rods 26 along their entire length.

Under drift roteres valsen 1 af elektromotoren 7 ved ind-trukne stempelstænger 16 over mineralfiberbanens 38 overflade 41, og opvarmningsstavene 26 forvarmes ved strømtilgang til rørvarmelegemerne 32 til en ønsket og even-10 tuelt af termoføleren overvåget temperatur. Rotationen under foropvarmningsfasen tilvejebringer jævne varmetab for de enkelte opvarmningsstave 26 og markeringsribber 30 og dermed disses jævne opvarmning uden individuel temperaturregulering for hver enkelt opvarmningsstav.In operation, the roller 1 of the electric motor 7 is rotated by retracted piston rods 16 over the surface 41 of the mineral fiber web 38, and the heating rods 26 are preheated by current access to the tube heater bodies 32 to a desired and possibly temperature-controlled temperature. The rotation during the preheating phase provides uniform heat loss for the individual heating rods 26 and marking ribs 30 and hence their even heating without individual temperature control for each heating rod.

Ved produktionsstart udskydes stempelstængerne 16, og valsen 1 sænkes ned på mineralfiberbaneoverfladen 41, og der kan foretages en finindstilling af valsens højdestilling over mineralfiberbanen 38 ved hjælp af elektromoto-20 ren 21 og justeringsdrevet 18. Indstillingen vælges hensigtsmæssigt således, at de periferiske markeringsribber 30 på valsen 1 indtrykker mineralfiberbanens 38 overflade 41 under dannelse af et trug 42. Jo dybere truget 42 indtrykkes for en given mineralfiberbane 38, desto større er 25 pressetrykket og påvirkningsvarigheden til forbedring af markeringsribbernes 30 varmeledning til mineralfibermate-rialet. Baneoverfladen 41 er typisk udækket og dannes altså af selve mineralfiberuordenen, men overfladen 41 kan også frembyde en kaschering enten i form af et over-30 træk på mineralfiberbasis eller ud fra andre fibre.At the start of production, the piston rods 16 are released and the roller 1 is lowered onto the mineral fiber web surface 41 and a fine adjustment of the height of the roller can be made over the mineral fiber web 38 by means of the electric motor 20 and the adjustment drive 18. The setting is suitably chosen so that the peripheral marking ribs 30 the roll 1 depresses the surface 41 of the mineral fiber web 38 to form a trough 42. The deeper the trough 42 is pressed for a given mineral fiber web 38, the greater the compressive pressure and impact duration to improve the heat conduction of the marking ribs 30 to the mineral fiber material. The web surface 41 is typically uncovered and thus formed by the mineral fiber disorder itself, but the surface 41 may also provide a caching either in the form of a mineral fiber coating or from other fibers.
Herved har markeringsribberne 30 en temperatur på en typisk størrelsesorden af 400 °C og frembringer en ved en stiplet linie 43 antydet zone for opløsning af bindemid-35 let i mineral fiberbanen 38, der skifter farve. På denne måde opstår der, svarende til det på fig. 3 synlige mønster for markeringsribberne 30, markeringsstreger på mi-Hereby, the marking ribs 30 have a temperature of a typical order of 400 ° C and produce a zone indicated by a dashed line 43 for dissolving the binder 35 in the mineral fiber web 38 which changes color. In this way, similar to that of FIG. 3 visible patterns for marking ribs 30, marking lines on

9 neralfiberbaneoverfladen 41, der strækker sig på tværs af banens siderande. Ved finjustering via justeringsdrevet 18 kan varmeovergangsbetingelserne styres således, at der opnås en optisk ren markering med skarpe rande, uden at 5 mineralfiberbanens 38 materiale påvirkes ud over en opløsningszone 43 med ringe dybde.9, the non-fibrous web surface 41 extending across the lateral edges of the web. By fine-tuning via the adjusting drive 18, the heat transition conditions can be controlled so as to obtain an optically clean mark with sharp edges, without affecting the material of the mineral fiber web 38 beyond a low-resolution solution zone 43.
Ved hjælp af tandhjulene 8 og 9 kan der opnås en varig drift af valsen 1 synkront med mineralfiberbanens 38 10 fremføringshastighed. Hensigtsmæssigt anvendes der dertil en jævnstrømsmotor som elektromotor 7. I det viste udførelseseksempel anvendes der dog en drejestrømsmotor, der er forbundet med drevet 8 gennem et friløb 44 således, at ved drift af valsen 1 fra mineral fiberbanen 38 kan val-15 sens 1 omløbshastighed overstige omløbshastigheden for elektromotoren 7. Valsedrevet via elektromotoren 7 tjener i dette tilfælde udelukkende til opretholdelse af en omløbstalsmæssig ukritisk minimal rotationshastighed i den optrukne hvilestilling ved bortfald af medføringen fra 20 mineral'fiberbanen 38 til at tilvejebringe en jævn opvarmning af opvarmningsstavene 26.By means of the gears 8 and 9, a durable operation of the roller 1 can be obtained synchronously with the speed of advance of the mineral fiber web 38 10. Conveniently, a DC motor is used as an electric motor 7. In the illustrated embodiment, however, a rotary current motor is connected to the drive 8 through a freewheel 44 such that, when operating the roller 1 from the mineral fiber web 38, the rolling speed of the roller 15 may exceed In this case, the drive driven by the electric motor 7 serves solely for maintaining an orbital numerically uncritical minimum rotational speed in the drawn-up rest position when the feed from the mineral fiber web 38 is dispensed to provide an even heating of the heating rods 26.
Ved aktivering af justeringsdrevet 18 kan man indstille overgangsbetingelserne mellem markeringsribberne 30 og 25 mineralfiberbaneoverfladen 41 som omtalt ovenfor til dannelse af optimale markeringslinier. Ved en given fremføringshastighed og konsistens af mineralfiberbanen 38 kan man dog også give afkald på en sådan finjustering, idet der da også kan arbejdes med en fast forindstilling af 30 valsens 1 indtrykningsforhold i mineralfiberbaneoverfladen 41. På denne måde kan lejekontruktionen for valsen 1 forsimples i væsentlig grad. Hvis man derudover kan holde vægten af valsen 1 således, at der alene ved en vægtba-lastning af baneoverfladen 41 fra vægten af valsen 1 til-35 vejebringes en ønsket indtrædningsdybde, kan presseorganet 14 i driftsstillingen kobles trykløst således, at valsen 1 blot ved sin egen vægt hviler på mineralfiber- 10By activating the alignment drive 18, the transition conditions between the marking ribs 30 and the mineral fiber web surface 41 can be set as discussed above to form optimal marking lines. However, at a given feed rate and consistency of the mineral fiber web 38, such fine tuning can also be waived, since a fixed presetting of the impression ratio of the roller 1 in the mineral fiber web surface 41. In this way, the bearing structure of the roller 1 can be substantially simplified. degree. In addition, if the weight of the roller 1 can be maintained so that only a desired depth of entry can be obtained by pressing the weight surface of the web surface 41 from the weight of the roller 1, the pressing means 14 in the operating position can be pressurized in such a way that own weight rests on mineral fiber 10

banen 38. I dette tilfælde kan en for kraftig indtrængning undgås ved, at markeringsribberne 30 ikke rager ud fra valsens 1 kontinuerte yderflader 29 med adskillige millimeter, eksempelvis ca. 8 mm, men ligger inden for 5 den kontinuerte valseoverflade 29, så at denne, i det væsentlige i form af dækpladerne 36, bidrager til at bære vægten og således undgår en for kraftig lokal indtrængning. Den viste udførelsesform med fra valseyderfladen 29 udragende markeringsribber 30 egner sig dog i særlig grad 10 til drift af valsen 1 fra mineralfiberbanen 38.web 38. In this case, excessive penetration can be avoided by the marking ribs 30 not projecting from the continuous outer surfaces 29 of the roll 1 by several millimeters, e.g. 8 mm, but is within the continuous roller surface 29 so that, substantially in the form of the cover plates 36, it contributes to carrying the weight and thus avoids excessive local penetration. However, the embodiment shown with marking ribs 30 projecting from the roller surface 29 is particularly suitable for operating the roller 1 from the mineral fiber web 38.
