Description

Formålet med foreliggende oppfinnelse er å tilveie-bringe en teppeflis med hard bunn, hvor spenningene er utløst, slik at' teppef lisen vil ligge plant uten rynker eller buler når den legges på et gulv. The purpose of the present invention is to provide a carpet tile with a hard bottom, where the stresses are released, so that the carpet tile will lie flat without wrinkles or bulges when it is laid on a floor.

Andre formål og fordeler ved oppfinnelsen vil fremgå av følgende beskrivelse av den foretrukne utføringsform av oppfinnelsen i forbindelse med tegningen, hvor: Figur 1 viser en stanseinnretning som benyttes for oppslissing av den harde bunn på teppefliser, Figur 2 er et perspektivriss av et parti av et stanse-verktøy som brukes ved oppfinnelsen, Figur 3 viser skjematisk et grunnriss av stanseverk-tøyet som benyttes ved oppfinnelsen, og Figur 4 er et perspektivisk utsnitt av en hardbunn-teppeflis med utsnitt for avlasting av spenningen i teppeflisen. Other purposes and advantages of the invention will be apparent from the following description of the preferred embodiment of the invention in connection with the drawing, where: Figure 1 shows a punching device used for slitting the hard bottom of carpet tiles, Figure 2 is a perspective view of part of a punching tool used in the invention, Figure 3 schematically shows a ground plan of the punching tool used in the invention, and Figure 4 is a perspective section of a hard floor carpet tile with a section for relieving the tension in the carpet tile.

Det henvises først til figur 4 hvor der er vist et parti av en teppeflis 10som i hovedsaken består av et antall luvgarn 12 som med sine bunnender er innstøpt i et normalt relativt tett bindelag 14, f.eks. polyvinylklorid, slik at disse forankres fast til overflaten på buhndukmaterialet 16. Til bunndukmateri-alets 16 underflate er fastklebet et annet polymerisk bunnmateri-ale 18, i det følgende benevnt "hardbunn" (hardback), og som også, om ønskelig, kan bestå av herdet polyvinylklorid. Reference is first made to Figure 4, where a portion of a carpet tile 10 is shown, which mainly consists of a number of pile yarns 12 which, with their bottom ends, are embedded in a normally relatively dense binding layer 14, e.g. polyvinyl chloride, so that these are firmly anchored to the surface of the bottom cloth material 16. Another polymeric bottom material 18 is glued to the bottom surface of the bottom cloth material 16, hereinafter referred to as "hard back", and which can also, if desired, consist of hardened polyvinyl chloride.

Som kort omtalt ovenfor vil man ved bruk av harbunn-teppefliser stå overfor det problem at enkelte fliser ikke vil ligge plant etter leggingen, som følge av indre spenninger som forårsaker at flisen buler. For å avhjelpe dette forhold anven-des teppeflis-snittemaskinen som i figur 1 er generelt angitt ved 20, for å frembringe et antall innsnitt i hardbunnplaten 18 til teppeflisen 10. Teppeflis-snittemaskinen 20 omfatter et stativ 22 på hvilket ved hjelp av passende bolter 24 er fastboltet en bæreramme 26 på hvilken er montert bæreelementet 28 samt et antall opprettstående stang- eller søyleelementer 30 som i toppar-tiene holdes sammen av tverrstaver 32. Skyvbart montert på søy-lene 30 er trykkflaten 34 som samvirker med stanseverktøyet 36 som er montert på bæreelementet 28. Også montert på tverrstavene 32 er et pneumatisk eller hydraulisk påvirkbart stempel 38 med stem-pelstang 40forbundet med trykkflaten 34. As briefly discussed above, when using harbun carpet tiles, you will be faced with the problem that some tiles will not lie flat after laying, as a result of internal stresses that cause the tile to bulge. To remedy this situation, the carpet tile cutting machine is used, which in figure 1 is generally indicated at 20, to produce a number of cuts in the hard bottom plate 18 for the carpet tile 10. The carpet tile cutting machine 20 comprises a stand 22 on which, by means of suitable bolts 24 is bolted a support frame 26 on which is mounted the support element 28 as well as a number of upright bar or column elements 30 which are held together in the top parts by cross bars 32. Slideably mounted on the columns 30 is the pressure surface 34 which cooperates with the punching tool 36 which is mounted on the support element 28. Also mounted on the cross bars 32 is a pneumatically or hydraulically actuable piston 38 with piston rod 40 connected to the pressure surface 34.

Ved bruk av den ovenfor beskrevne maskin plaserer teppeflisen 10 på stanseverktøyet 36 på bæreelementet 28 med hard-bunnflaten vendt nedover. Stemplet 38 aktiveres slik at trykkflaten 34 skyves nedover og trykker flisen 10 mot stanseverktøyet 36. Trykkflaten 34 og stanseverktøyet holdes i snittinngrep med teppeflisen 10 i omtrent ett til to sekunder under et trykk på ca. 17,5 kg/cm 2for utforming av innsnitt i hardbunnplaten 18 til teppeflisen 10. Deretter heves trykkflaten, teppeflisen fjernes, en ny teppeflis som skal snittes plaseres i snittstilling og fremgangs-måten gjentas.. When using the machine described above, the carpet tile 10 is placed on the punching tool 36 on the support element 28 with the hard bottom surface facing downwards. The piston 38 is activated so that the pressure surface 34 is pushed downwards and presses the tile 10 against the punching tool 36. The pressure surface 34 and the punching tool are held in cut engagement with the carpet tile 10 for approximately one to two seconds under a pressure of approx. 17.5 kg/cm 2 for designing incisions in the hard base plate 18 for the carpet tile 10. The pressure surface is then raised, the carpet tile is removed, a new carpet tile to be cut is placed in the cut position and the procedure is repeated..

I den foretrukne utføringsform av oppfinnelsen består stanseverktøyet av en rekke korrugerte, riflede skjærelementer 43 som danner en form som vist i figur 2 og 4. Ved betraktning av figur 2 og 4 vil det forstås at korrugeringenes høydepunkter 44 trenger inn i hardbunnplaten til en dybde nær inntil bunnduklaget In the preferred embodiment of the invention, the punching tool consists of a series of corrugated, fluted cutting elements 43 which form a shape as shown in figures 2 and 4. When considering figures 2 and 4, it will be understood that the high points 44 of the corrugations penetrate into the hard bottom plate to a depth of up to the base fabric layer

16, mens de øvrige deler av den korrugerte overflate får en mindre inntrengningsdybde, slik at man oppnår de ønskede innsnitt i hardbunnplaten 18 for avlasting av indre spenninger uten oppdeling eller delaminering av bunnmaterialet. Ikke bare frembringer stanse-verktøyets korrugeringer en tiltalende overflateeffekt på bunnpla-ten, men de eliminerer også rettlinjet oppsnitting av hardbunnplaten. 16, while the other parts of the corrugated surface get a smaller penetration depth, so that the desired incisions in the hard bottom plate 18 are achieved for relieving internal stresses without dividing or delaminating the bottom material. Not only do the punch tool's corrugations produce a pleasing surface effect on the base plate, but they also eliminate straight-line cutting of the hard base plate.

I en foretrukket utføringsform er stanseverktøyene som vist på figur 3 slik innbyrdes anordnet at de danner et rute-nett eller gitter hvor avstanden mellom tilstøtende parallelle stanseverktøy ved teppeflisens kant er mindre enn avstanden innover på teppet. En har funnet at en slik avstandsfordeling gir et mer effektivt spenningsavlastingsmønster enn om avstanden mellom alle parallelle tilstøtende stanseverktøy var den samme. In a preferred embodiment, the punching tools as shown in figure 3 are mutually arranged in such a way that they form a grid or grid where the distance between adjacent parallel punching tools at the edge of the carpet tile is smaller than the distance inwards on the carpet. It has been found that such a distance distribution provides a more effective stress relief pattern than if the distance between all parallel adjacent punching tools were the same.

Stanseverktøyet kan fremstilles på mange forskjellige måter, hvorav mange innbefatter fremstilling av lange sammenhengende korrugerte elementer av samme lengde eller bredde som trykkflaten 34 og innstøping av disse i platen. Stanseverktøyene i mot- satt retning lages så i korte lengder og innpasses mellom og vinkelrett på tilstøtende lange lengder. Omvendt kan stanse-verktøyet bestå av alle de små enkeltsegmenter i sammenføyet til-stand og innstøpt i trykkplaten 34 slik at de danner det stanse-mønster som er vist i figur 3. The punching tool can be produced in many different ways, many of which include the production of long continuous corrugated elements of the same length or width as the pressure surface 34 and embedding these in the plate. The punching tools in the opposite direction are then made in short lengths and fitted between and perpendicular to adjacent long lengths. Conversely, the punching tool can consist of all the small individual segments in a joined state and embedded in the pressure plate 34 so that they form the punching pattern shown in figure 3.

Det vil være klart fra ovenstående at man "her har kom-met frem til et apparat og en fremgangsmåte som enkelt og effektivt tilveiebringer en teppeflis hvor hardbunnplaten er forsynt med innsnitt for avlasting av indre spenninger, slik at teppeflisen ikke danner buler ved legging på et gulv. It will be clear from the above that an apparatus and a method have been arrived at here that simply and effectively provide a carpet tile where the hard bottom plate is provided with incisions for relieving internal stresses, so that the carpet tile does not form bulges when laid on a floor.
