Description
Fremgangsmåte for fremstilling av puter.Method for manufacturing cushions.
I Foreliggende oppfinnelse angår fremstilling av puter, særlig av såkalte "fullt-ferdige" puter som består av en polstring dannet vanligvis av polyuretanskum og av en kledning eller et trekk bestående som oftest av stoff, jersey, kunstlær eller annet lignende materiale. The present invention relates to the manufacture of cushions, in particular so-called "completely finished" cushions which consist of a padding usually formed of polyurethane foam and of a covering or cover usually consisting of fabric, jersey, artificial leather or other similar material.
Den fremgangsmåte som tidligere var brukt for dette formål besto i ved hjelp av en ramme å trekke og feste til det ovre parti av en stopeform en elastisk og/eller varmformbar kledning, f.eks. et tekstilstoff som er gjort tett med lag av polyvinylklorid eller polyuretan, et kunstlær eller lignende materialer} med eller uten opphetning av stoffet å tilveiebringe et vakuum i formen, slik at materialet i kledningen presses mot innsiden av stopeformen og antar dens form; å stope deretter i formen hvis innside da er dekket med stoff eller annet kledningsmateriale en skummende polyuretanblanding; å la blandingen ekspandere i den lukkede form, idet polymerisasjonen finner sted med eller uten oppvarmning avhengig av arten av de brukte polyoler og isocyanater, og endelig å åpne formen og å fjerne fra denne polstringen av polyuretanskum til hvilken tekstilstoffet eller kunstlæret er vedheftet. The method that had previously been used for this purpose consisted in using a frame to pull and fasten to the upper part of a stop shape an elastic and/or thermoformable covering, e.g. a textile fabric that is made dense with layers of polyvinyl chloride or polyurethane, an artificial leather or similar materials} with or without heating the fabric to provide a vacuum in the mold, so that the material in the lining is pressed against the inside of the stop mold and assumes its shape; then stuffing into the mold, the inside of which is then covered with fabric or other cladding material, a foaming polyurethane mixture; to allow the mixture to expand in the closed form, the polymerization taking place with or without heating depending on the nature of the polyols and isocyanates used, and finally to open the form and to remove from this padding of polyurethane foam to which the textile fabric or synthetic leather is attached.
Dersom stopeformen er meget komplisert og/eller dyp, foretar man, for vakuumet tilveiebringes, en varmformning av tekstilstoff et eller annet kledningsmateriale, for det anbringes i formen. If the stop mold is very complicated and/or deep, a hot forming of textile fabric or other cladding material is carried out, because the vacuum is provided, for it to be placed in the mold.
De ferdige puter som er fremstilt ved hjelp av denne fremgangsmåte, har imidlertid på grunn av at kledningen over hele overflaten hefter meget sterkt til skummet, den ulempe at de efter en viss brukstid får et meget uestetisk utseende. Under bruk vil nemlig skummet og dermed også kledningen eller trekket som hefter til skummet, danne varige folder og rynker. Det er klart at efter en kortere eller lengre tid vil kledningen være varig merket av disse folder og rynker. However, due to the fact that the coating over the entire surface adheres very strongly to the foam, the finished cushions produced using this method have the disadvantage that after a certain period of use they acquire a very unsightly appearance. During use, the foam and thus also the covering or cover that adheres to the foam, will form permanent folds and wrinkles. It is clear that after a shorter or longer time, the covering will be permanently marked by these folds and wrinkles.
On det ved sluttbehandlingen av puten er onskelig å tilfoye ytterligere til kledningsmaterialet til den fremstilte pute, f.eks. et stykke av tekstilstoff eller annet materiale ved sying When finishing the cushion, it is desirable to add more to the covering material of the manufactured cushion, e.g. a piece of textile fabric or other material when sewing
jeller sveising, er dette vanskelig og ofte umulig å'utforeor welding, this is difficult and often impossible to carry out
denne operasjon på en symaskin eller en sveisemaskin.på grunn av at kledningen vedhefter fullstendig til fyllingsskummet. this operation on a sewing machine or a welding machine. due to the fact that the coating adheres completely to the filling foam.
For å eliminere disse ulemper, tilveiebringer foreliggende oppfinnelse en fremgangsmåte for fremstilling av puter, særlig av polyuretanskum stopt in situ i en kledning som er anbragt f.eks. ved hjelp av vakuum i en form, hvilken kledning vedhefter til fyllingsmaterialet bare på visse på forhånd bestemte steder. In order to eliminate these disadvantages, the present invention provides a method for the production of cushions, in particular of polyurethane foam stuffed in situ in a covering which is placed e.g. by means of vacuum in a mold, which coating adheres to the filling material only in certain predetermined places.
Efter at kledningen er anbragt i formen dekker man nemlig.de onskede vedheftesteder med maskeringsdeler, anbringer derefter på den resterende overflate av kledningen et produkt som tillater fjernelsen fra formen og hindrer vedheftingen av skummet, og fjerner, for den skummende blanding stopes i formen, maskeringsdelene som avgrenser de overflater på hvilke den skummende blanding vil vedhefte til kledningen. After the cladding is placed in the mould, one covers the desired attachment points with masking parts, then applies to the remaining surface of the cladding a product which allows the removal from the mold and prevents the adhesion of the foam, and removes, because the foaming mixture is stopped in the mould, the masking parts which delimits the surfaces on which the foaming mixture will adhere to the cladding.
Oppfinnelsen vil bedre forstås av den efterfolgende beskrivelse under henvisning til tegningene som viser som ikke begrensende eksempel puten samt forskjellige faser av fremstillingen av denne. Fig. 1 er et snitt gjennom en pute fremstilt ved fremgangsmåten ifolge oppfinnelsen. Fig. 2 til 7 er snitt som viser forskjellige stadier av fremgangsmåten. Fig. 8 viser et eksempel på komprimeringen av puten fremstilt ved hjelp av fremgangsmåten ifolge oppfinnelsen; og The invention will be better understood from the following description with reference to the drawings which show, as a non-limiting example, the pillow and various phases of its production. Fig. 1 is a section through a pillow produced by the method according to the invention. Fig. 2 to 7 are sections showing different stages of the method. Fig. 8 shows an example of the compression of the pillow produced by means of the method according to the invention; and
Fig. 9 viser sying av en sluttkledning til putetrekket.Fig. 9 shows the sewing of an end covering for the cushion cover.
Som vist på figurene 2-7 fremstilles ifolge oppfinnelsen denAs shown in figures 2-7, it is produced according to the invention
på fig. 1 viste pute, hvis overside har ribber 1 og hvis kledning eller trekk 2 vedhefter til skummet 3 bare i de forsenkede partier 4 og til sidene 5 på putens omkrets, således: Ved hjelp av tetningsrammen 7 festes til oversiden av stopeformen 6, hvis i on fig. 1 shown cushion, whose upper side has ribs 1 and whose covering or cover 2 adheres to the foam 3 only in the recessed parts 4 and to the sides 5 on the circumference of the cushion, as follows: By means of the sealing frame 7 is attached to the upper side of the stop mold 6, if in
I bunn har samme kontur som den onskede putes overside, kledningen 2 som består f.eks. av tekstilstoff, jersey eller kunstlær (fig. 2). Derpå tilveiebringes ved hjelp av kanalen 8 et vakuum i det indre av formen, således at kledningen 2 ligger an mot veggene i formen (fig. 3). I formen 6 anbringes så på kledningen 2 og på de steder hvor denne skal vedhefte skummet 3, maskeringsdeler 9, f.eks. klebebånd, papirstykker, tre, kartong, metall eller hvilket som helst annet materiale, hvorpå f.eks. ved hjelp av en sproytepistol 10 eller en svamp overflaten av kledningen påfores et lag 11 av formlosende middel på basis av mikrokrystallinsk voks eller et klebehindrende middel på silikonbasis, men fortrinnsvis dannet av en glycerol eller annet lignende stoff og særlig av vann som inneholder hydroksylradikaler i overskudd i forhold til NCO-radikaler i den skummende blanding av polyuretan (fig. 4), hvilket forårsaker en under-fornetting i hoyden av veggene i overflateceller av polyuretanskummet. Derefter fjernes maskeringsdeleene under hvilke ikke er avsatt noe formlosende middel, og den skummende fyllingsblanding fylles i stopeformen (fig. 5), i hvilken, efter at lokket 12 er satt på plass, polyuretanblandingen ekspanderer og fyller formen fullstendig (fig. 6). At the bottom, the cover 2, which consists of e.g. of textile fabric, jersey or artificial leather (fig. 2). A vacuum is then provided by means of the channel 8 in the interior of the mold, so that the cladding 2 rests against the walls of the mold (fig. 3). In the form 6, masking parts 9, e.g. adhesive tape, pieces of paper, wood, cardboard, metal or any other material, on which e.g. with the help of a spray gun 10 or a sponge, a layer 11 of mold-releasing agent based on microcrystalline wax or an anti-adhesion agent based on silicone, but preferably formed of a glycerol or other similar substance and especially of water containing excess hydroxyl radicals, is applied to the surface of the cladding in relation to NCO radicals in the foaming mixture of polyurethane (Fig. 4), which causes an under-crosslinking in the height of the walls of surface cells of the polyurethane foam. Then the masking parts are removed under which no mold release agent has been deposited, and the foaming filling mixture is filled into the stop mold (fig. 5), in which, after the lid 12 is put in place, the polyurethane mixture expands and fills the mold completely (fig. 6).
Efter en polymerisasjon ved forhoyet temperatur eller ved omgiv-elsestemperatur avhengig av fyllingsmateriale, åpnes lokket 12, tetningsrammen 7 fjernes og puten tas ut av formen, idet kledningen 2 da hefter til polyuretanskummet utelukkende på de steder som ikke er dekket av laget av formlosende middel (fig. 7). After a polymerization at an elevated temperature or at ambient temperature depending on the filling material, the lid 12 is opened, the sealing frame 7 is removed and the cushion is taken out of the mold, the covering 2 then adheres to the polyurethane foam exclusively in the places that are not covered by the layer of mold release agent ( Fig. 7).
Oppfinnelsen angår også som nytt industrielt produkt puter fremstilt ved hjelp av fremgangsmåten og bestående av et fyllmateriale, såsom polyuretanskum, til hvilket kledningen hefter utelukkende på visse steder. The invention also relates as a new industrial product to cushions produced using the method and consisting of a filling material, such as polyurethane foam, to which the covering adheres exclusively in certain places.
Til en slik pute kan, som vist på fig. 9, på grunn av at under-kanten av kledningen ikke hefter til skummet, med letthet sys et tekstilstoff eller et trekk 13 ved hjelp av en symaskin eller sveisemaskin. For such a pillow, as shown in fig. 9, because the lower edge of the covering does not adhere to the foam, a textile fabric or a cover 13 is easily sewn using a sewing machine or welding machine.
Dessuten blir kledningen av puten ikke forringet under en sammen- In addition, the cover of the cushion is not degraded during a combined
I trykking 14 (fig. 8) av puten, fordi selv om selve skummet dan-' ner folder 15, vil den ikke-vedheftende del. av kledningen 2 danne en naturlig fold 16 som ikke er utsatt for spenninger. In printing 14 (Fig. 8) of the cushion, because even if the foam itself forms folds 15, the non-adherent part will. of the cladding 2 form a natural fold 16 which is not exposed to tension.
Oppfinnelsen er selvsagt ikke begrenset til den beskrevne fremgangsmåte eller til puter fremstilt ved hjelp av fremgangsmåten, men omfatter alle varianter som ikke faller utenfor rammen av oppfinnelsen. The invention is of course not limited to the described method or to cushions produced using the method, but includes all variants that do not fall outside the scope of the invention.
