Opfindelsen angår et pladeformet isolationselement omfattende et pladeformet legeme af et isolationsmateriale med en heri anbragt armering og eventuelt et dæklag på legemets ene overflade og iøvrigt af den i krav l's indledning angivne art.The invention relates to a plate-shaped insulating element comprising a plate-shaped body of an insulating material with a reinforcement disposed therein and, optionally, a covering layer on one surface of the body and otherwise of the kind specified in the preamble of claim 1.
I tysk fremlæggelsesskrift nr. 2.437.924 er der beskrevet en tagbelægning bestående af tagplader af ovennævnte art.German Patent Specification No. 2,437,924 discloses a roof covering consisting of roof panels of the above-mentioned type.
Disse kendte tagplader består af et varmeisolationslag, på hvis overside der er anbragt et dæklag, og til hvis underside der er fastgjort et stift bærelag, som ved pladernes kanter har opadbøjede rande.These known roof plates consist of a heat insulation layer, on the upper side of which a cover layer is arranged, and to whose underside there is attached a rigid support layer, which has upwardly curved edges at the edges of the plates.
Ved udlægning af en tagbelægning af sådanne plader anbringes der over hosliggende opadbøjede rande på bærelagene U-formede fugedækelementer og oven over disse tætningsstrim ler.When laying a roof covering of such plates, overlying curved edges are placed on the supporting layers U-shaped joint cover elements and above these sealing strips.
De nævnte plader kan i området op til de opadbøjede sidekanter have forstærkningslister, der strækker sig parallelt med sidekanterne, og de kan desuden omfatte forstærkningslister, der er anbragt vinkelret på de førstnævnte. Fastgørelsen af den kendte tagbelægning opnås ved hjælp af med mellemrum og i udsparinger i varmeisolationslaget anbragte holdeklemmer, hvis ene ende er U-formet, og anbringes således, at den griber ind over et U-formet fugedækelement, og hvis anden ende med en skrue eller lignende fastgøres til underlaget.Said plates may have reinforcing strips extending parallel to the side edges in the region up to the upward curved side edges, and may further comprise reinforcing strips perpendicular to the former. The attachment of the known roofing is achieved by means of intervals and recesses arranged in the heat insulation layer, one end of which is U-shaped, and arranged so that it engages over a U-shaped joint cover element and the other end with a screw or similar is attached to the substrate.
De stive bærelag, der som nævnt indgår i de kendte tagplader samt brugen af de nævnte U-formede fugedækelementer og holdeklemmerne bevirker, at tagpladerne bliver dyre at fremstille og at udlægge.The rigid support layers which, as mentioned, form part of the known roofing sheets as well as the use of the said U-shaped joint cover elements and the holding clamps make the roofing sheets become expensive to manufacture and to lay out.
Formålet med opfindelsen er at tilvejebringe et enkelt og billigt pladeformet isolationselement af den i indledningen angivne art, som på enkel måde og ved hjælp af standardelementer kan fastgøres sikkert til et underlag.The object of the invention is to provide a simple and inexpensive plate-shaped insulating element of the kind specified in the preamble, which can be securely attached to a substrate in a simple way and by means of standard elements.
Dette formål opnås ifølge opfindelsen med et pladeformet isolationselement, som er ejendommeligt ved, at der i hver kantzone og i den tilstødende del af det pladeformede legeme er anbragt et af glasfibre dannet armeringslag.This object is achieved according to the invention with a plate-shaped insulating element, which is characterized in that in each edge zone and in the adjacent part of the plate-shaped body a reinforcing layer formed of glass fibers is arranged.
Anbringelsen af et af glasfibre dannet armeringslag på 146947 2 den angivne måde sikrer, at man uden at risikere, at kantzonerne brækker af, f.eks. under de store spændinger, som en vindpåvirkning kan give anledning til, kan fastgøre isolationselementerne ifølge opfindelsen til et underlag under anvendelse af relativt korte standardfastgørelsesmidler, såsom skruer eller søm. Eksempelvis kan man føre skruer gennem kantzonerne og derved fastgøre disse direkte til underlaget.The application of a reinforcing layer formed of glass fibers in the manner indicated ensures that without risk of the edge zones breaking off, e.g. under the high stresses that a wind effect can cause, the insulation elements of the invention can be secured to a substrate using relatively short standard fasteners such as screws or nails. For example, screws can be passed through the edge zones, thereby attaching them directly to the substrate.
Der kan også anbringes fastgørelsesmidler i fugen mellem de hosliggende kanter, og der kan anvendes underlagsskiver eller -plader, som griber ind over falsene på de hosliggende plader.Fasteners may also be placed in the joint between the adjacent edges, and backing discs or plates may be used which engage over the folds of the adjacent plates.
Ved at anbringe fastgørelseselementerne i fugen mellem to hosliggende plader kræves der kun et minimalt antal af fastgørelseselementer til opnåelse af en sikker fastgørelse af elementerne til underlaget.By placing the fastening elements in the joint between two adjacent plates, only a minimum number of fastening elements is required to obtain a secure fastening of the elements to the substrate.
Efter fastgørelsen af isolationselementerne kan fastgørelsesorganerne, som er anbragt i den rendeformede zone, afdækkes ved at anbringe udfyldningsstykker af isolationsmateriale med dimensioner svarende til dimensionerne af den nævnte rendeformede zone. Der opnås således en isolerende belægning, som har en plan overflade, der er velegnet som underlag for en tagbelægning, og som kan betrædes uden at blive beskadiget. Ydermere opnås den væsentlige fordel med isolationselementerne ifølge den foreliggende opfindelse, at en herpå anbragt tagbelægning også kan betrædes uden at blive beskadiget, ved at fastgørelsesorganerne presses op gennem tagbelægningen.After securing the insulation elements, the fasteners located in the gutter zone can be uncovered by affixing insulating material fillers having dimensions corresponding to the dimensions of said gutter zone. Thus, an insulating coating is obtained which has a flat surface which is suitable as a substrate for a roof covering and which can be treaded without being damaged. Furthermore, the essential advantage of the insulating elements of the present invention is that a roof covering applied thereto can also be treaded without being damaged by pressing the fastening means through the roof covering.
En yderligere fordel ved det således dannede isolationslag er, at kuldebroer undgås. Da fugen mellem to isolationsplader tillige er overdækket undgås vanddamptransmission igennem laget, ligesom røggasser i tilfælde af brand under isolationslaget forhindres i gennem fugerne at trænge op til tagbelægningen og antænde denne.A further advantage of the insulation layer thus formed is that cold bridges are avoided. Since the joint between two insulating sheets is also covered, water vapor transmission through the layer is avoided, and in the event of fire under the insulation layer, flue gases are prevented from penetrating through the joints and igniting it.
Ved fastgørelse af isolationselementerne på lodrette flader, f.eks. udvendigt på husvægge, er den skjulte fastgørelse og resulterende plane overflade meget fordelagtig, når væggen skal overfladebehandles.When attaching the insulation elements to vertical surfaces, e.g. exterior of house walls, the concealed attachment and resulting flat surface is very advantageous when the wall is to be surface treated.
I en foretrukket udførelsesform for isolationselementet ifølge opfindelsen strækker laget af glasfibre sig over 146947 3 hele isolationslegemet fra den ene fals til den anden. Herved opnås udover en særlig god armering i kantområdet en stabilisering af hele isolationselementet, som på denne måde forhindres i at deformeres i væsentlig grad ved varierende temperaturer.In a preferred embodiment of the insulating element according to the invention, the layer of glass fibers extends over the entire insulating body from one seam to the other. Hereby, in addition to a particularly good reinforcement in the edge region, a stabilization of the entire insulating element is obtained, which in this way is prevented to deform substantially at varying temperatures.
Laget af glasfibre er fortrinsvis anbragt således, at det danner en belægning på bunden af falsen, idet der herved opnås en særlig god forstærkning af det under falsen liggende kantområde.The layer of glass fibers is preferably arranged so as to form a coating on the bottom of the seam, thereby obtaining a particularly good reinforcement of the edge area under the seam.
Ved anvendelse af et glasfiberlag, der strækker sig fra isolationselementets ene kant til den modsatte, og når isolationsmaterialet består af celleplast, er det med henblik på at opnå størst mulig stabilisering af elementet vigtigt, at glasfiberlaget ligger nøjagtigt midt i elementet.When using a fiberglass layer extending from one edge of the insulating element to the opposite, and when the insulating material consists of cellular plastic, in order to obtain the greatest possible stabilization of the element, it is important that the fiberglass layer is exactly in the middle of the element.
Det foretrækkes derfor, at falsdybden udgør halvdelen af elementets tykkelse, og at glasfiberlaget, som strækker sig uafbrudt fra den ene kant til den anden, dækker bunden af de to false.It is therefore preferred that the depth of the fold is half the thickness of the element and that the fiberglass layer, which extends continuously from one edge to the other, covers the bottom of the two folds.
Isolationselementet består fortrinsvis af to lag celleplast, som ved klæbning er forbundet med oversiden henholdsvis undersiden af laget af glasfibre, idet produktionen af et sådant element kan gennemføres på simpel måde.Preferably, the insulating element consists of two layers of cellular plastic which, by adhesion, are connected to the top or the underside of the glass fiber layer, the production of such an element being carried out in a simple manner.
Isolationslegemet kan bestå af en eller flere slags isolationsmaterialer. Således kan det være sammensat af to slags celleplast, hvor det lag, der ligger over glasfiberlaget, består af én slags celleplast, og det lag, der ligger under glasfiberlaget, består af en anden slags celleplast. I stedet for at anvende to lag celleplast, kan man også anvende et lag celleplast kombineret med et eller flere lag af et andet isolationsmateriale, f.eks. mineraluld, såsom stenuld og glasuld.The insulating body may consist of one or more kinds of insulating materials. Thus, it may be composed of two types of cellular plastics, wherein the layer overlying the fiberglass layer consists of one kind of cellular plastic and the layer beneath the fiberglass layer consists of a different kind of cellular plastic. Instead of using two layers of cellular plastic, one may also use one layer of cellular plastic combined with one or more layers of another insulating material, e.g. mineral wool, such as rock wool and glass wool.
Opfindelsen angår også fremgangsmåder til fremstilling af et pladeformet isolationselement af den ovenfor beskrevne art.The invention also relates to processes for producing a plate-shaped insulating element of the kind described above.
En fremgangsmåde ifølge opfindelsen er ejendommelig ved, at der på oversiden af en isolationsplade armeret med et lag glafibre påklæbes en, eventuelt med et armerings- eller dæklag forsynet, anden plade af et isolationsmateriale, idet sidstnævnte plade har en sådan i forhold til den første 4 U6947 plade reduceret bredde og/eller længde, at der ved mindst to modstående kantområder ved samme overflade på det sammensatte isolationselement dannes false.A method according to the invention is characterized in that on the upper side of an insulation plate reinforced with a layer of fiberglass, another, optionally provided with a reinforcing or covering layer is adhered to an insulating material, the latter plate having such a relation to the first 4. U6947 plate reduced width and / or length that false at least two opposite edge regions at the same surface of the composite insulation element are formed.
Ved at fremstille de to isolationsplader med forskellige dimensioner og sammenklæbe dem på en sådan måde, at der ved kantområderne dannes false, opnås en bedre udnyttelse af isolationsmaterialet sammenlignet med det tilfælde, hvor falsene udformes ved at bortfræse en del af isolationsmaterialet. Ydermere vil man ved præfabrikationen af isolationslaget med armeringslaget af glasfibre kunne etablere optimale betingelser til sikring af en god forbindelse mellem glas-fiberarmeringen og isolationslaget. Endelig er den beskrevne fremgangsmåde velegnet til brug ved fabriksmæssig fremstilling af de omtalte pladeformede isolationselementer.By fabricating the two insulation sheets of different dimensions and gluing them in such a way as to form false at the edge regions, better utilization of the insulation material is compared to the case where the seams are formed by milling away part of the insulation material. Furthermore, in the prefabrication of the insulation layer with the reinforcing layer of glass fibers, it is possible to establish optimum conditions for ensuring a good connection between the glass fiber reinforcement and the insulation layer. Finally, the disclosed method is suitable for use in the factory manufacture of the aforementioned plate-shaped insulation elements.
Glasfiberlaget i den nævnte første plade af isolationsmateriale består fortrinsvis af glasfiberflor, som er indlejret i eller ved hjælp af et bindemiddel bundet til pladens overflade.The fiberglass layer of said first sheet of insulating material preferably consists of fiberglass web embedded in or by means of a binder bonded to the surface of the sheet.
Sådanne plader kan på kendt vis fremstilles kontinuerligt ved at blande to komponenter, hvoraf den første består af en polyol, en skumstabilisator, en katalysator og vand, og den anden består af isocyanat, i et blandeapparat af kendt art, og ved straks efter sammenblandingen at udsprøjte den dannede blanding i et ensartet lag på et underlag, f.eks. en bane af glasfiberflor. Der indtræder herved en opskumning og hærdning, som kan fremskyndes ved at føre materialet gennem en ovn, hvori materialet understøttes af f.eks. en bånd- eller kædetransportør. Glasfiberfloret bliver herved integreret i celleplastpladens underside.Such plates can be manufactured in a known manner continuously by mixing two components, the first one consisting of a polyol, a foam stabilizer, a catalyst and water, and the second consisting of isocyanate, in a mixer of a known kind, and immediately after mixing the spraying the resulting mixture into a uniform layer on a substrate, e.g. a web of fiberglass flooring. Thereby a foaming and curing occurs which can be accelerated by passing the material through an oven in which the material is supported by e.g. a belt or chain conveyor. The fiberglass floor is thereby integrated into the underside of the cellular plastic sheet.
Ved fremstilling af en plade, hvor tillige overfladen omfatter et glasfiberlag, kan dette, f.eks. en bane af et glasfiberflor, udlægges på det opskummelige materiale, inden dette føres gennem ovnen. Under passagen gennem ovnen holdes armeringslaget fortrinsvis presset mod overfladen af det opskummelige materiale til dannelse af en bane med en forudbestemt tykkelse.In the manufacture of a plate, the surface of which also comprises a fiberglass layer, this may, e.g. a web of a fiberglass web is laid on the foamable material before passing through the furnace. During passage through the furnace, the reinforcing layer is preferably pressed against the surface of the foamable material to form a web of a predetermined thickness.
Ved fremstilling af et elastisk celleplastlag anvendes fortrinsvis som polyolkomponent en blanding af polypropylen-glykol (med en molekylvægt på ca. 2000) og sorbitol i et 5 146947 vægtforhold på ca. 4:1. Ved fremstilling af hårde celleplasttyper anvendes polyoler med lavere molekylvægte.In the manufacture of an elastic cell-plastic layer, a mixture of polypropylene glycol (having a molecular weight of about 2000) and sorbitol in a weight ratio of about 2,000 is preferably used as a polyol component. 4: 1. In the manufacture of hard cellular plastics, lower molecular weight polyols are used.
Skumstabilisatoren er f.eks. polyethoxypolydimethyl-siloxan, og katalysatoren er fortrinsvis triethylendiamin.The foam stabilizer is e.g. polyethoxypolydimethylsiloxane, and the catalyst is preferably triethylenediamine.
En anden fremgangsmåde til fremstilling af det omtalte pladeformede element er ejendommelig ved, at et underlag, som består af en eller flere plader af isolationsmateriale, og som ved i det mindste to modstående kanter er belagt med et af glasfibre dannet armeringslag, påføres et lag opskummeligt plastmateriale på en sådan måde, at der ved længdekanterne dannes smalle zoner, som er fri for det op-skummelige materiale, at det opskummelige materiale bringes til at opskumme og hærde, og at der på oversiden af det således dannede skumplastlag eventuelt påføres et dæklag.Another method of making the said sheet-shaped element is characterized in that a layer consisting of one or more sheets of insulating material and which is coated with at least two opposing edges with a reinforcing layer formed of glass fibers is foamable. plastic material in such a way that at the longitudinal edges narrow zones are formed which are free of the foamable material, that the foamable material is caused to foam and harden, and that a cover layer is optionally applied to the upper surface of the foamed layer thus formed.
Denne fremgangsmåde frembyder ligeledes den fordel, at der opnås en optimal udnyttelse af isolationsmaterialet, idet intet af dette går tabt, når det øvre lag ved opskumning fremstilles direkte på det nedre lag. Herudover undgås oplagring af plader til dannelse af det øvre isolationslag.This method also offers the advantage of optimum utilization of the insulation material, none of which is lost when the upper layer is foamed directly on the lower layer by foaming. In addition, storage of sheets to form the upper insulation layer is avoided.
Desuden spares udgiften til klæber og klæbeproces ved foreningen af de to lag til dannelse af slutproduktet. Endelig er også sidstnævnte fremgangsmåde velegnet til brug ved fabriksmæssig fremstilling af de omtalte plader.In addition, the cost of adhesive and adhesive process is saved by joining the two layers to form the final product. Finally, the latter method is also suitable for use in the factory manufacture of the said sheets.
Pladen eller pladerne, der anvendes som underlag for fremstillingen af det øverste celleplastlag, kan f.eks. bestå af polyurethancelleplast fremstillet som ovenfor anført, og det anvendte opskummelige plastmateriale, som derefter påføres pladen eller pladerne af isolationsmateriale, kan f.eks. bestå af de samme bestanddele.The plate (s) used as a support for the manufacture of the upper cellular plastic layer may e.g. consist of polyurethane cellular plastic made as stated above, and the foamable plastic material used, which is then applied to the plate or sheets of insulating material, can e.g. consist of the same constituents.
Pladen eller pladerne med det derpå anbragte lag af opskummeligt materiale føres fortrinsvis gennem en ovn for at fremskynde opskumningen og hærdningen af det dannede celleplastlag, og der kan eventuelt på skumlagets overside samtidig pålægges et dæklag, f.eks. et glasfibervæv- eller flor belagt med bitumen.The plate (s) with the layer of foamable material then placed is preferably passed through an oven to accelerate the foaming and curing of the formed cellular plastic layer, and optionally, at the top of the foam layer, a covering layer, e.g. a fiberglass tissue or web coated with bitumen.
For at forhindre, at laget af opskummeligt materiale flyder ud til pladens eller pladernes længdekanter, kan man føre to kantstillede papirstrimler, hvis nedre kanter berører den eller de armerede plader, og som er anbragt i 146947 6 en forudbestemt afstand fra kanten, gennem ovnen synkront med pladen eller pladerne.In order to prevent the layer of foamable material from flowing to the longitudinal edges of the plate or plates, two edge strips of paper, the lower edges of which touch the reinforced plate (s) and which are arranged at a predetermined distance from the edge, can be synchronously passed through the oven. with the plate or plates.
Opfindelsen skal herefter beskrives nærmere under henvisning til tegningen, hvor fig. 1 viser et snit vinkelret på pladens plan gennem en foretrukket udførelsesform for et pladeformet isolationselement ifølge opfindelsen, fig. 2 viser et snit vinkelret på tagisolationen gennem en del af en tagisolation fremstillet ved fremgangsmåden ifølge opfindelsen, og fig. 3 skematisk illustrerer et apparat til brug ved fremstilling af isolationselementer ifølge opfindelsen.The invention will now be described in more detail with reference to the drawing, in which fig. 1 shows a section perpendicular to the plane of the plate through a preferred embodiment of a plate-shaped insulating element according to the invention; FIG. 2 shows a section perpendicular to the roof insulation through part of a roof insulation made by the method according to the invention; and FIG. 3 schematically illustrates an apparatus for use in the manufacture of insulation elements according to the invention.
I fig. 1 er der vist en isolationsplade sammensat af et nedre lag 1 og et øvre lag 2 og et glasfiberlag 3, der strækker sig fra den ene sidekant af laget til den modsatte. Laget 2 har en mindre bredde end laget 1, hvorved der dannes en fals 4 ved hver sidekant. Laget 2 er på oversiden forsynet med et dæk- eller armeringslag 5.In FIG. 1, there is shown an insulation plate composed of a lower layer 1 and an upper layer 2 and a fiberglass layer 3 extending from one side edge of the layer to the opposite. Layer 2 has a smaller width than layer 1, thereby forming a seam 4 at each side edge. The top layer 2 is provided with a tire or reinforcing layer 5 on the upper side.
I fig. 2 betegner 20 et profileret ståldæk, hvorpå der er anbragt to isolationsplader 21 af den omhandlede art. Pladerne er anbragt således, at to med false forsynede kanter støder op til hinanden. Pladerne 21 er fastgjort til ståldækket 20 ved hjælp af skruer 22, som er anbragt i mellemrummet mellem pladerne, og som er indskruet i huller i ståldækket 20. Skruerne 22 udøver ved hjælp af underlagsskiver 23 et tryk på pladerne på begge sider af det område, hvor de grænser op til hinanden, og der opnås herved en sikker fastgørelse til ståldækket 20. Den af de hosliggende false dannede rende er udfyldt med et i tværsnit rektangulært isolationslegeme 24. Der opnås med dette en fuldstændig afdækning af skruerne 22 og tilhørende underlagsskiver 23. Det rektangulære isolationslegeme 24 har fortrinsvis en bredde, som er lidt større end den nævnte rende, hvormed det sikres, at legemet efter indføring fastholdes i renden med oversiden i flugt med isolationspladernes overside.In FIG. 2 denotes 20 a profiled steel deck on which are placed two insulation plates 21 of the kind in question. The plates are arranged so that two false edges are adjacent to each other. The plates 21 are secured to the steel deck 20 by means of screws 22 which are arranged in the space between the plates and which are screwed into holes in the steel deck 20. The screws 22 apply, by means of washers 23, a pressure on the plates on both sides of the area. where they adjoin each other, thereby securing a secure attachment to the steel deck 20. The gutter formed by the adjacent false is filled with a cross-section rectangular insulating body 24. A complete covering of the screws 22 and associated washers 23 is thereby achieved. The rectangular insulating body 24 preferably has a width which is slightly larger than said gutter, thereby ensuring that after insertion, the body is retained in the gutter with its upper face in alignment with the upper side of the insulating plates.
Den således opnåede isolation danner et velegnet underlag for en egentlig tagdækning, som kan fremstilles på 7 146947 konventionel måde.The insulation thus obtained forms a suitable substrate for an actual roofing which can be manufactured in conventional manner.
Der er i fig. 2 vist en profilering af ståldækket, som strækker sig parallelt med pladernes falskanter, men det skal bemærkes, at pladerne i praksis normalt vil blive anbragt med falskanterne vinkelret på profileringen.In FIG. 2 shows a profiling of the steel deck which extends parallel to the false edges of the plates, but it should be noted that in practice the plates will normally be arranged with the false edges perpendicular to the profiling.
Det i fig. 3 viste apparat omfatter et endeløst bånd 30, som understøttes af to båndruller, hvoraf kun en, 31, er vist. Båndrullen 31 er forbundet med ikke-viste drivorganer til bevægelse af det endeløse bånd 30 i den med pil 32 viste retning.The FIG. 3 comprises an endless belt 30 supported by two belt rollers, only one of which, 31, is shown. The tape reel 31 is connected to non-shown drive means for moving the endless tape 30 in the direction shown by arrow 32.
Apparatet omfatter yderligere et endeløst bånd 33, der understøttes af to båndruller, hvoraf kun en, 34, er vist. En af disse båndruller er forbundet med et ikke-vist drivorgan til bevægelse af båndet 33 i den med pil 35 viste retning.The apparatus further comprises an endless belt 33 supported by two belt rollers, of which only one, 34, is shown. One of these belt rollers is connected to a non-shown drive means for moving the belt 33 in the direction indicated by arrow 35.
Ovenover det øvre løb af båndet 33 er der anbragt et blande- og sprøjteapparat 36, som er forbundet med organer 37,38 til tilførsel af bestanddelene til dannelse af en opskummelig plastblanding.Above the upper run of the belt 33, a mixing and spraying apparatus 36 is provided, which is connected to means 37, 38 for supplying the ingredients to form a foamable plastic mixture.
Over det øverste løb af båndet 33 er der anbragt en udjævningsvalse 39, og båndet er på det pågældende sted understøttet af en understøtningsvalse 40.A smoothing roller 39 is arranged over the upper race of the belt 33 and the belt is supported at that location by a support roller 40.
Som det fremgår af fig. 3 fremføres der ved hjælp af båndet 30 en serie af pladeformede elementer 41, som er anbragt med sammenstødende endekanter.As shown in FIG. 3, a series of plate-shaped elements 41 are arranged by means of the band 30, which are arranged with adjacent end edges.
Under fremføringen af serien af disse plader 41 pålægges der ved længdekanterne strimler af slippapir ved hjælp af en rulle 42. Slippapiret tjener til at forhindre, at opskummeligt materiale, som måtte blive afsat i disse kantzoner, klæber fast til pladerne 41, hvis oversider er pålagt et glasfiberlag.During the advancement of the series of these plates 41, strips of abrasive paper are applied at the longitudinal edges by means of a roll 42. The abrasive paper serves to prevent foamy material which may be deposited in these edge zones from adhering to the plates 41 whose upper sides are applied a fiberglass layer.
Under den fortsatte fremføring af serien af plader 41 forenes med disse et lag opskummeligt materiale 43 dannet på det endeløse bånd 33.During the continued advancement of the series of plates 41, a layer of foamable material 43 formed on the endless tape 33 is joined.
Som følge af tilstedeværelsen af strimlerne af slippapir langs kanterne af pladerne kan eventuelt herpå påført opskummeligt materiale let senere fjernes, f.eks. ved hjælp af ikke-viste roterende knive, der er anbragt over båndet 30 ved dets kanter, og som renskærer det hærdede U6947 8 lag 43 til den ønskede bredde.Due to the presence of the strips of sandpaper along the edges of the sheets, any foam material applied thereto may be easily removed later, e.g. by means of non-rotating blades shown above the band 30 at its edges, which clean the cured layer U6947 8 to the desired width.
Herved opnås, at der ved lamineringen af laget af op-skummeligt materiale og serien af pladeformede isolationselementer dannes false ved længdekanterne.This results in the lamination of the layer of foamable material and the series of plate-shaped insulation elements forming false at the longitudinal edges.
