Verfahren zum Abdichten von Kissen-ÜberzügenMethod of sealing pillow covers
Die vorliegende Erfindung bezieht sich auf die Herstellung von Kissen, besonders von solchen mit Jerseystoff-Überzügen, oder dergleichen, und sie betrifft im besonderen ein Verfahren zum Abdichten der Überzüge solcher Kissen.The present invention relates to the manufacture of pillows, particularly those with jersey fabric covers, or the like, and particularly relates to a method of sealing the covers of such pillows.
Das zur Zeit überwiegend angewandte Verfahren besteht darin, dass ein elastischer und/oder warmformbarer Überzug, wie z.B. ein durch aufgetragenes Polyvinylchlorid, Polyurethan, oder dergleichen, abgedichteter Stoff mittels eines Rahmens über dem Oberteil einer Form gespannt und befestigt wird, die man je nach Erwärmen oder Nichterwärmen des Stoffes luftleer macht, damit sich das Überzugsmaterial gegen die Innenwände der Form presst und deren Gestalt annimmt ; diese innen mit Stoff oder anderem Überzugmaterial bedeckte Form wird dann mit einer schäumenden Polyurethan-Mischung ausgegossen, die sich in der geschlossenen Form ausdehnt ; die Polymerisation erfolgt warm oder kalt je nach der Art der verwendeten Polyo-Ie und Isozyanate j schliesslich wird die Form geöffnet undThe currently predominant method is that an elastic and / or thermoformable coating, such as e.g. a fabric sealed by applied polyvinyl chloride, polyurethane, or the like by means of a frame the upper part of a mold is stretched and fastened, which is evacuated depending on the heating or non-heating of the fabric makes so that the coating material presses against the inner walls of the mold and takes their shape; this inside with Fabric or other covering material covered mold is then poured with a foaming polyurethane mixture, which expands in closed form; the polymerization is carried out warm or cold, depending on the type of Polyo-Ie used and isocyanates j finally the mold is opened and

aus ihr die Polyurethan-Füllung zusammen mit dem auf ihr haftenden Stoff herausgenommen.taken out of it the polyurethane filling together with the substance adhering to it.
Bei diesem bekannten Herstellungsverfahren spielt die Dichtschicht eine dreifache Rolle, und zwar :In this known manufacturing process, the sealing layer plays a role a threefold role, namely:
- den Stoff luftdicht zu machen, um ihn unter Vakuum anpressen zu können,- to make the fabric airtight so that it can be pressed under vacuum,
- den Stoff luftdicht zu machen, damit die Schaummischung, die in den unter Vakuum angepressten Stoff gegossen wird, an keiner Stelle durch ein Loch der Dichtschicht, und somit in das Stoffgewebe austritt,- to make the fabric airtight so that the foam mixture that is poured into the fabric pressed under vacuum, at no point through a hole in the sealing layer and thus into the fabric,
- sehr elastisch zu sein, damit sich der Jerseystoff in der Giessform unter Annahme ihrer Formen richtig anpresst und keine Knickstellen aufweist.- to be very elastic, so that the jersey fabric presses properly in the mold, assuming its shapes, and has no kinks.
Die derzeitigen Dichtschichten werden so hergestellt, dass Polyvinylchlorid-Filmen, expandierte Polyvinylchlorid-Folien oder Polyurethan-Filmen auf den Jerseystoff oder dergleichen, aufgetragen oder aufgeklebt werden.The current sealing layers are made so that polyvinyl chloride films, expanded polyvinyl chloride sheets or polyurethane films on the jersey fabric or the like, applied or glued.
Die mit diesen bekannten Verfahren erzielten Ergebnisse sind nicht sehr vollkommen.The results obtained with these known methods are not very perfect.
Es erweist sich, dass die in dieser Weise abgedichteten Stoffe ungenügend elastisch sind und auf dem Überzug Knickstellen enthalten.It turns out that the fabrics sealed in this way are insufficiently elastic and have kinks on the cover contain.
Ausserdem sind die Polyurethan-Filmen, die am elastischsten sind, sehr häufig mikroporös, sodass sich beim Anpressen unter Vakuum bestimmte Mikrolöcher vergrössern und die Folie für den Schaum somit durchlässig machen.In addition, the polyurethane films are the most elastic are, very often microporous, so that when pressed against Vacuum certain micro-holes and enlarge the foil thus make it permeable for the foam.
Weiterhin ist bei den bekannten Verfahren der Verbrauch an Dichtfolien sehr bedeutend, denn sie bedecken die gesamte Stoff-Fläche, während nur ein Stoffstück benutzt wird, dasFurthermore, the consumption of sealing foils is very important in the known methods, because they cover the whole Fabric surface while only using one piece of fabric that
509882/0719509882/0719
die Form des Kissens hat. Auch die Stoffabfalle sind nicht mehr verwendbar und nicht wieder kardierbar, da die Dichtfolien fest auf dem Stoff haften.has the shape of the pillow. Even the garbage is not longer usable and not re-cardable, as the sealing foils adhere firmly to the fabric.
Die vorliegende Erfindung bezweckt die Beseitigung dieser Nachteile.The present invention aims to overcome these drawbacks.
Das erfindungsgemässe Verfahren zum Abdichten der Kissenüberzüge besteht darin, dass auf der einzigen Stoffseite, die dem Vakuum ausgesetzt ist und die Schaummischung aufnimmt, anstelle des derzeitigen Kunststoffes, wie z.B. des ungenügend dichten und wenig elastischen Polyurethans, ein Kautschuklatex- oder Kunststofflatex-Film angebracht wird.The method according to the invention for sealing the cushion covers consists in the fact that on the only side of the fabric that is exposed to the vacuum and absorbs the foam mixture, instead of the current plastic, such as the insufficiently dense and poorly elastic polyurethane Rubber latex or plastic latex film is applied.
Gemäss einem Ausführungsbeispiel besteht das Verfahren zum Abdichten der Kissenüberzüge darin, eine sehr glatte Scliablone, z.B. aus Glas, herzustellen, die der Grosse der zu dichtenden Stofffläche entspricht ; diese Platte versieht man mit einem Ausformmittel, z.B. einer Seifenlösung, worauf mittels Spritzpistole eine oder mehrere Schichten von Kautschuklatex aufgetragen werden, dem eine anti-oxydierende und vulkanisierende Mischung, z.B. Schwefel, Zinkoxyd, oder dergleichen, beigefügt wird ; der so gebildete Film wird mit Warmluft oder durch eine andere, diesen Vorgang beschleunigende Wärmequelle getrocknet und dann eine letzte Latexschicht aufgetragen, auf welcher sofort der Jerseystoff oder dergleichen aufgebracht wird. Diese letzte Latexschicht gewährleistet das Festhaften des Stoffes auf dem Latexfilm nach dem Trocknen der Gesamtbeschichtung, nach welchem man die Schablone vom Latex trennt. Man erhält so ein mit einem Latexfilm beschichteter Stoffabschnitt von der Grosse der Schablone, der elastisch und einwandfrei dicht ist.According to one embodiment, the method for sealing the cushion covers consists in producing a very smooth template, for example made of glass, which corresponds to the size of the surface of the fabric to be sealed; this plate is provided with a molding agent, for example a soap solution, after which one or more layers of rubber latex are applied by means of a spray gun, to which an anti-oxidizing and vulcanizing mixture, for example sulfur, zinc oxide, or the like, is added; the film formed in this way is dried with warm air or by another heat source which accelerates this process and then a last layer of latex is applied, on which the jersey material or the like is immediately applied. This last layer of latex ensures that the material adheres to the latex film after the entire coating has dried, after which the stencil is separated from the latex. This gives a section of fabric coated with a latex film, the size of the template, which is elastic and perfectly tight.
Gemäss einem anderen Ausführungsbeispiel der Erfindung besteht das Verfahren zum Abdichten der Kissenbezüge darin, die Schablone in ein Latexbad zu tauchen und ihre beiden Seiten mitAccording to another embodiment of the invention, there is the method of sealing the pillowcases is to dip the stencil in a latex bath and both sides with it
509882/0719509882/0719
einem Latexfilm zu überziehen, deren Dicke durch die sich folgenden Eintauchvorgänge bestimmt wird ; sie wird an der freien Luft oder in einem Ofen, oder dergleichen, getrocknet. Unmittelbar nach dem letzten Eintauchen werden beide Seiten der Schablone mit Stoff belegt und nach dem Trocknen der Gesamtbeschichtung die Schablone von den zwei abgedichteten Stoffabschnitte getrennt.to coat a latex film, the thickness of which is determined by the following dipping operations; she will at the in the open air or in an oven or the like. Immediately after the final dip, both sides will the stencil is covered with fabric and after the entire coating has dried, the stencil is sealed off from the two Sections of fabric separated.
Das Auflegen des Stoffes auf die Schablone kann z.B. dadurch erfolgen, dass sie auf den flachen Stoff aufgelegt und damit die untere Schablonenseite belegt wird, worauf ein zweiter Stoffabschnitt auf der Schablonenoberseite anzubringen ist.The laying of the fabric on the template can be done, for example, by laying it on the flat fabric and so that the lower side of the stencil is covered, whereupon a second section of fabric is to be attached to the upper side of the stencil is.
Die Erfindung findet ihre Anwendung auf dem Gebiete der Kissenherstellung, insbesondere der Kissen für die Sitze von Automobilen, oder dergleichen.The invention finds its application in the field of pillow manufacture, in particular the cushions for the seats of automobiles, or the like.
Die Erfindung beschränkt sich nicht auf die beschriebenen Ausführungsbeispiele. Es besteht die Möglichkeit von Änderungen, besonders hinsichtlich der Anwendung des Verfahrens, ohne dadurch den Schutzbereich der Erfindung zu Überschreiten. The invention is not restricted to the exemplary embodiments described. There is a possibility of changes, especially with regard to the application of the method, without thereby exceeding the scope of the invention.
