Description

"Vorrichtung zum flächigen Verbinden von Folien oder dünnwandigen Formteilen aus thermoplastischem Kunststoff mit in einer zwei- oder mehrteiligen Blas- oder Spritzform auszuformenden Teilen aus thermoplastischem Kunststoff" Die Erfindung bezieht sich auf eine Vorrichtung zum flächigen Verbinden von Folien oder dünnwandigen Formteilen aus thermoplastischem Kunststoff mit in einer zwei- oder mehrteiligen Blas- oder Spritzform auszuformenden Teilen aus thermoplastischem Kunststoff, wobei die Folie bzw. das Formteil mittels Vakuum an der Innenwand der Blas- bzw. Spritzform festgehalten und dann beim Ausformen der Teile durch den Blas- bzw. "Device for the surface joining of foils or thin-walled Molded parts made of thermoplastic material with in a two-part or multi-part Blow or injection mold parts to be formed from thermoplastic material "Die The invention relates to a device for the planar joining of foils or thin-walled molded parts made of thermoplastic material with in a two- or multi-part blow or injection molds to be molded parts made of thermoplastic material, wherein the film or the molded part by means of a vacuum on the inner wall of the blow molding or Injection mold held and then when the parts are molded by the blow molding or

Spritzdruck sowie die Temperatur des sich in plastischem Zustand befindlichen auszuformenden Kunststoffs mit diesem verschweißt wird, indem ein Teil der Wand eines der Blasformteile als gesondert eine und ausfahrbarer Stempel ausgebildet ist, dessen Stirnfläche einen Teil der Blasforminnenfläche bildet und für die Erzeugung eines Vakuums ausgebildet ist, nach Patent.... (Patentanmeldung D 43 492 X/39a2).Injection pressure as well as the temperature of the plastic state located Plastic to be molded is welded to this by part of the wall one of the blow molded parts is designed as a separate and extendable punch is, the end face of which forms part of the inner surface of the blow mold and for the production a vacuum is formed, according to patent .... (patent application D 43 492 X / 39a2).

Es wurde gefunden, daß eine flächige haltbare Kaschierung von Leder, Textilgeweben, Papier und dergl. bei Verwendung von sog. Schweißhilfsmitteln möglich ist.It has been found that a two-dimensional, durable lamination of leather, Textile fabrics, paper and the like are possible when using so-called welding aids is.

Hierzu ist es notwendig, die dem thermoplastischen Schlauch zugewandte Fläche aus Gewebe, Leder oder Papier vorher mit Dispersionen, z.B. aus Mischpolymerisaten, Kunstharzen, Neopren, Kautschuk oder Latex, zu beschichten. Die Auswahl des zu verwendenden Schweißhilfsmittels richtet sich nach den zum Einsatz kommenden thermoplastischen Rohstoff. Als Schweißhilfsmittel können ausserdem auch Lösungen der verwendeten Rohstoffe Verwendung finden. So z. B. bei Polystyrol ein Lösungsmittelgemisch aus 20 Teilen Polystyrol III, gelöst in 80 Teilen Benzol.To do this, it is necessary to place the one facing the thermoplastic hose Surface made of fabric, leather or paper beforehand with dispersions, e.g. from copolymers, To coat synthetic resins, neoprene, rubber or latex. Choosing which one to use Welding aid depends on the thermoplastic used Raw material. Solutions of the used can also be used as welding aids Find use of raw materials. So z. B. with polystyrene from a solvent mixture 20 parts of polystyrene III dissolved in 80 parts of benzene.

Aufgrund der Eigenwärme des thermoplastischen Schlauches ist es möglich, die miteinander zu verbindenden Flächen heiß zu versiegeln. So können z.B. vorbehandelte Flaschenetiketten direkt bei dem Blasvorgang auf Flaschen gesiegelt werden.Due to the inherent heat of the thermoplastic hose, it is possible to heat seal the surfaces to be joined together. For example, pretreated Bottle labels are sealed directly onto bottles during the blow molding process.

Weiter ist darauf zu achten, daß genügend Entluftungsmöglichkeiten zwischen den beiden zu verbindenden Schichten geschaffen werden. Dies geschieht vorzugsweise dadurch, daß man nach dem Aufbringen der Schweißhilfsmittel kleine Bohrungen oder Nadelstiche Uber die gesamte Fläche, etwa in Abständen von 5 bis 50 mm, verteilt anbringt, damit die zwischen den zu verbindenden Schichten verbleibende Luft entweichen kann.It is also important to ensure that there are sufficient ventilation options be created between the two layers to be joined. this happens preferably in that after the application of the welding aids, small Holes or pinholes over the entire surface, approximately at intervals of 5 up to 50 mm, distributed so that the remaining between the layers to be connected Air can escape.

Durch die Verwendung von Papieretiketten ergibt sich ausserdem gegenüber dem bisher bekannten Siebdruckverfahren der Vorteil, daß der Farbaufdruck nicht mehr verwischt, wodurch Ausschußmengen erheblich verringert werden können.The use of paper labels also results in opposite the previously known screen printing process has the advantage that the color print is not more blurred, whereby reject quantities can be reduced considerably.
