Description
Die Erfindung hat nun zum Zweck, spritzgeformte Stiefel zu schaffen, an denen das Aufbringen von Folien mit praktisch dem gleichen Automationsgrad auszuführen ist wie demjenigen der gesamten Produktion. Es wurde dabei - verglichen mit einigen der herkömmlichen Methoden - zwar eine gewisse Einschränkung in bezug auf Materialauswahl des eingebrachten Zweitmaterials in Kauf genommen, die Vorteile, die dadurch aber erreicht wurden, waren erstens nicht vorauszusehen und erlauben zweitens, das Aufbringen höchst rationell und wirtschaftlich zu gestalten. The invention now has the purpose of creating injection-molded boots on which the application of foils is to be carried out with practically the same degree of automation as that of the entire production. Compared to some of the conventional methods, a certain restriction with regard to the material selection of the introduced second material was accepted, the advantages that were achieved, firstly, were not foreseeable and secondly, the application was extremely efficient and economical shape.
Das erfindungsgemässe Verfahren zur Herstellung von druckgespritzten Siefeln aus Kunststoff oder Gummi, die mindestens eine einen Flächenteil überdeckende, fest mit letzterem verbundene Folie aufweisen, ist im Patentanspruch 1 definiert. The method according to the invention for the production of pressure-sprayed plastic or rubber seals, which have at least one film covering a surface part and firmly connected to the latter, is defined in claim 1.
Das erfindungsgemäss verarbeitete Material kann auf PVC oder Polyurethan basieren. Ebenso kann das Material hauptsächlich aus Kunst- oder Naturgummi bestehen. The material processed according to the invention can be based on PVC or polyurethane. Likewise, the material can mainly consist of synthetic or natural rubber.
Beim erfindungsgemässen Verfahren sollte darauf geachtet werden, dass die Schichtdicke der eingelegten Folienteile an den mit den Folienteilen überzogenen Stellen des Produktes höchstens die Hälfte der Schichtdicke des Stiefels ausmacht. Beim Überschreiten dieser Grenze ist zu befürchten, dass sich das nach dem Einlegen des Folienteils in die Spritzform eingespritzte, flüssige Material um die Folie nicht genügend gut verteilt. In the method according to the invention, care should be taken that the layer thickness of the inserted film parts at the points of the product covered with the film parts is at most half the layer thickness of the boot. If this limit is exceeded, it is to be feared that the liquid material injected into the injection mold after inserting the film part will not be distributed sufficiently well around the film.
Die Folienteile können zum Beispiel mittels eines Klebstoffs in die Spritzform eingeklebt werden; denkbar ist aber auch die Verwendung von Folienteilen, die auf einer Seite schon einen Klebstoff aufweisen. Aus solchen Folien würde dann das Motiv ausgeschnitten und in die Pressform eingebracht. The film parts can, for example, be glued into the injection mold using an adhesive; it is also conceivable to use film parts that already have an adhesive on one side. The motif would then be cut out of such foils and inserted into the press mold.
Die Folienteile können verschiedene Grössen und Formen aufweisen. Hauptsächlich wird hierbei jedoch vor allem an Verzierungen oder Bezeichnungen solcher Artikel gedacht. The film parts can have different sizes and shapes. However, the main focus is on decorations or names of such articles.
Der Stiefel muss dabei nicht in einem Einspritzvorgang abgeschlossen werden, er kann ohne weiteres zum Beispiel in zwei solcher Arbeitsschritte produziert werden. Bei den letztgenannten Vorgängen ist jedoch darauf zu achten, dass die eingebrachte Folie nicht über den Materialgrenzen der in verschiedenen Arbeitsgängen eingebrachten Spritzmaterialien zu liegen kommt. The boot does not have to be completed in one injection process, it can easily be produced in two such steps, for example. In the latter processes, however, care must be taken that the film introduced does not lie above the material limits of the spray materials introduced in different processes.
Als Versuch einer Erklärung der Entdeckung, die hinter dieser Erfindung steht, kann eventuell die folgende Überlegung dienen: Beim Eintreten des flüssigen Spritzmaterials wird die dem flüssigen Kunststoff oder dem Gummi zugekehrte The following consideration may serve as an attempt to explain the discovery behind this invention: When the liquid spray material enters, it turns to the liquid plastic or rubber

Seite der eingelegten Folienteile durch deren Wärme aufgeweicht. Dadurch wird eine eigentliche Verschweissung der holienteile mit dem Grundmaterial, d. h. dem Kunststoff oder dem Gummi erreicht. Side of the inserted film parts softened by their heat. This will actually weld the holie parts to the base material, i. H. the plastic or the rubber.
Zur Illustration der Erfindung werden nun zwei Beispiele 5 summarisch beschrieben: Two examples 5 are now summarized to illustrate the invention:
Beispiel 1 example 1
Auf einem Extruderautomat mit Spritzformkarussell und zwei angeschlossenen Druckspritzanlagen wurden gelbe 10 On an extruder with an injection mold carousel and two connected pressure injection systems, yellow 10
PVC-Kinderstiefel mit weisser Sohle gespritzt. In die geöffneten Spritzformen wurden aus einer schwarzen PVC-Folie einer Schichtdicke von 0,2 mm Motive an einen äusseren Formteil geklebt. Die Einspritzung der beiden Stiefelteile (Schaft und Sohle) in die Form geschah anschliessend automatisch. Nach 15 PVC boots injected with white sole. In the opened injection molds, a black PVC film with a layer thickness of 0.2 mm was used to glue motifs to an outer molded part. The injection of the two boot parts (shaft and sole) into the mold then took place automatically. After 15
Entnahme der so verzierten Stiefel zeigte sich das völlig unverzerrte Motiv an der genau vorgesehenen Stelle und wies eine einwandfreie Haftung im Hauptmaterial des Stiefels auf. When the boots decorated in this way were removed, the completely undistorted motif was shown at the precise location and showed perfect adhesion in the main material of the boot.
Beispiel 2 Example 2
Auf einem ähnlichen Automaten wie im Beispiel 1 wurden schwarze Kinderstiefel mit brauner Sohle aus Kunstgummi (liquid rubber) druckgespritzt. In die geöffneten Spritzformen wurden aus einer weissen PVC-Folie einer Schichtdicke von ca. 0,2 mm Motive an einen äusseren Formteil geklebt. Die Einspritzung der beiden Stiefelteile (Schaft und Sohle) in die Form geschah anschliessend automatisch. Nach Entnahme der so verzierten Stiefel zeigte sich das völlig unverzerrte Motiv an der genau vorgesehenen Stelle und wies eine einwandfreie Haftung im Hauptmaterial des Stiefels auf. Black children's boots with brown soles made of synthetic rubber (liquid rubber) were pressure-sprayed on a machine similar to that in Example 1. In the opened injection molds, motifs were glued to an outer molded part from a white PVC film with a layer thickness of approx. 0.2 mm. The injection of the two boot parts (shaft and sole) into the mold then took place automatically. After removing the boots decorated in this way, the completely undistorted motif appeared in the exactly intended place and showed perfect adhesion in the main material of the boot.
