Das Heiss-Spritzformen von Schuhen und Stiefeln aus Elastomeren und Piastomeren ist bekannt. Es stellt eine Weiterentwicklung und spezielle Anwendung der in der einschlägigen Fachliteratur eingehend beschriebenen Heissspritz- und Heisspress-ForTtrungsverfahren dar.The hot injection molding of shoes and boots from elastomers and plastics is known. It puts a further development and special application of the hot injection molding process described in detail in the relevant specialist literature and hot-press extrusion processes.
Ebenso ist aus der Patentliteratur bekannt, bei den genannten Formungsverfahren in die Formteile, z.B. Folien, aus Materialien einzulegen. Beim Heissspritzen bzw. -pressen wird das eingelegte Teil mit dem Spritzmaterial verschweisst. Es ist zu beachten, dass die genannten Verfahren nur für solche Einlagematerialien geeignet sind, die erstens kompakt sind und zweitens ähnliche chemische und physikalische Eigenschaften wie das zu spritzende Material aufweisen. Solche Verbindungsverfahren sind z.B., neben dem Patentgesuch der Anmelderin dieser Erfindung, in der deutschen Patentschrift Nr. 833 118 undiin der deutschen Offenlegungsschrift 1 629 beschrieben.It is also known from the patent literature, in the named molding processes into the molded parts, e.g. foils, insert made of materials. During hot spraying or hot pressing, the inserted part is welded to the spray material. It should be noted that the methods mentioned are only suitable for insert materials that are firstly compact and, secondly, have similar chemical and physical properties as the material to be sprayed. Such Connection methods are e.g., in addition to the patent application of the applicant of this invention, in the German patent specification No. 833 118 and in German Offenlegungsschrift 1 629 described.
Bei der Schuhherstellung bildet das Einbringen des Futters, vor allem eines gut isolierenden Futters für Winterschuhe, unabhängig von der Art und von der Herstellungsweise der Schuhe einen speziellen Arbeitsgang: Vor oder nachIn shoe production, the introduction of the lining, especially a well-insulating lining for winter shoes, A special operation regardless of the type and method of manufacture of the shoes: before or after

Für gespritzte Kunststoffschuhe werden dabei vielfach Plüschgewebe als Isolierschichten eingesetzt. Das Gewebe wird mit der Grundschicht direkt an die Innenseite des Schuhobermaterials geklebt. Oft wird dabei auf dem Sohleninnenteil keine Isolierschicht angebracht.the completion of the shoe upper becomes the lining attached on the inside, practically always glued on. For injection-molded plastic shoes, there are many Plush fabric used as insulating layers. The fabric is attached directly to the inside of the base layer Glued shoe upper. Often no insulating layer is applied to the inner part of the sole.

Bei der Anwendung des erfindungsgemässen Verfahrens werden mit Vorteil Innenfutter aus Acrylfasern oder solche aus Polyester-Polypropylenfasern verwendet, die in Plüschgeweben vorliegen.When using the inventive In the process, inner linings made of acrylic fibers are advantageous or those made of polyester-polypropylene fibers are used, which are present in plush fabrics.
Bei der Verwendung der genannten, speziellen Innenfutter ist es wesentlich, dass auf das Grundgewebe der, Innenfutters eine relativ starre Baumwollgewebeware als Sohle des Innenmaterials und auf der Seite und am Schaft eine relativ elastische Baumwollwirkware aufgeklebt ist.When using the aforementioned, special inner lining, it is essential that the base fabric is used the, inner lining a relatively rigid cotton fabric as the sole of the inner material and on the side and on the A relatively elastic knitted cotton fabric is glued on the shaft.
Bei der Anwendung des erfindungsgemässen Verfahrens ist es von Vorteil, das Spritzgiessen des äusseren Schuhobermaterials bei Temperaturen zwischen 190 und 200 C und das Spritzgiessen der Sohle bei Temperaturen zwischen 195 und 205 C auszuführen.When using the method according to the invention it is advantageous to injection-mold the outer shoe upper material at temperatures between 190 and 200 ° C and the injection molding of the sole at temperatures between 195 and 205 C.
Das erfindungsgemässe Verfahren erlaubt es,The inventive method allows
Kunststoffschuhe mit einem beständigen Innenfutter praktisch in einem Arbeitsgang, d.h. während des Druckgiessens des Schuhs, auszuführen. Das spezielle Verfahren ergibt eine sehr gute Haftung zwischen dem aufgespritzten ElastGtaermaterial und dem Baumwollgewebe des Futters. Mittels des erfimlmKisgemässen Verfahrens wird erreicht, dass die beim Spritzvorgang flüssige Elastomermasse nicht in das Plüschgewebe des Futters eindringt. Der Aufbau des Futtermaterials bleibt vollständig erhalten. Versuche, das gleiche Verfahren nur mittels des Plüschgewebes f d.h, ohne die Baurawo 1!gewebekaschierung, auszuführen, zeigten negative Resultate * DasPlastic shoes with a durable inner lining practically in one operation, ie during the die-casting of the shoe. The special process results in very good adhesion between the sprayed-on ElastGtaermaterial and the cotton fabric of the lining. By means of the process according to the invention, it is achieved that the elastomer compound that is liquid during the injection process does not penetrate into the plush fabric of the lining. The structure of the lining material is completely retained. Experiments, the same procedure f that is, only by means of plush fabric, without the Baurawo 1! Fabric lamination to perform, showed negative results *

Plüschfutter wurde dabei weitgehend zerstört.Plush lining was largely destroyed in the process.
Im folgenden wird die Erfindung anhand eines Beispiels näher illustriert.The invention is illustrated in more detail below using an example.
Auf einem Bi-Pack-Extrudierautomat mit Spritzformkarussell und zwei angeschlossenen Druckspritzanlagen wurden schwarze Ski-Langlaufschuhe aus synthetischem Kautschuk gespritzt. In die geöffnete Spritzform wurde über die Fussform das Schuhinnenmaterial gestülpt, sodass der Plüsch an der Fussnegativform auflag und die Baumwollkaschierung aussen lag. Auf die Sohlenseite wurde hierauf die Brandsohle geklebt und angepresst. Diese besteht aus einem mit Kohlenstoffderivaten imprägnierten Zellulosematerial. Nach Schliessen der Druckgussform wurde in einem ersten Arbeitsgang der Schuhoberteil aus Synthetik-Kautschuk mit Compounders bei einer Temperatur von etwa 195 C eingespritzt. Gleich anschliessend wurde mit der zweiten Druckspritzanlage die Sohle eingespritzt, wobei das Rohmaterial hier ebenfalls im wesentlichen aus Synthetik-Kautschuk mit bestimmten Compounders und Füllstoffen besteht. On a bi-pack automatic extrusion machine with injection molding carousel and two connected pressure spray systems were black cross-country ski boots made of synthetic rubber injected. The shoe inner material was slipped over the foot shape into the open injection mold so that the Plush was on the negative foot form and the cotton lining was on the outside. On the sole side was on this the insole glued and pressed on. This consists of a cellulose material impregnated with carbon derivatives. After the die-casting mold had been closed, the upper part of the shoe was made from synthetic rubber in a first step injected with compounders at a temperature of about 195 C. Immediately afterwards the second Pressure injection system injected the sole, whereby the raw material here also consists essentially of synthetic rubber with certain compounders and fillers.
Kurz darauf konnte der Pressform der fertige Schuh - natürlich in seiner Rohform - inklusive des Innenfutters entnommen werden. Das als Innenfutter verwendete Acrylfaser-Plüschgewebe war völlig intakt und die Haftung der Baumwollgewebeschichten an dem aufgespritzten Syntheti-k-Shortly afterwards, the press mold was able to produce the finished shoe - in its raw form, of course - including the inner lining can be removed. The acrylic fiber plush fabric used as the inner lining was completely intact and the adhesion of the cotton fabric layers on the sprayed-on synthetic
Kautschuk war tadellos. Nirgends konnte ein Eindringen des gespritzten Materials in das Plüschgewebe festgestellt werden.Rubber was impeccable. No penetration of the sprayed material into the plush fabric was found anywhere will.
