Description
Bilderschallplatte Die bisher im Handel erhältlichen, fabrikmäßig hergestellten Schallplatten sind schwarz oder einfarbig und undurchsichtig.Bilderschallplatte The previously commercially available, factory-made produced records are black or plain and opaque.
Versuche, Schallplatten herzustellen, die aus transparenten thermoplastischen Kunststoffen bestehen und in der durchsichtigen Tonträgerschicht Buntdrucke, Lichtbilder oder andere bildliche Darstellungen einschließen, die auf den Inhalt der Tonaufzeichnungen Bezug haben, sind bisher erfolglos geblieben.Try making records that are made of transparent thermoplastic There are plastics and colored prints and photographs in the transparent sound carrier layer or other pictorial representations based on the content of the sound recordings Have so far been unsuccessful.
Das Scheitern dieser Versuche ist darauf zurückzuführen, daß die bei der Verarbeitung von Thermoplasten zu Schallplatten erforderlichen hohen Preßdrücke dazu führen, daß die einzupressenden Bildeinlagen durch die unvermeidbaren seitlichen Materialverschiebungen während des Preßvorganges zwangsläufig zerreißen müssen.The failure of these attempts is due to the fact that the the processing of thermoplastics into records requires high compression pressures lead to the fact that the picture inserts to be pressed in by the unavoidable lateral Material displacements must inevitably tear during the pressing process.
Die vorliegende Erfindung vermeidet dieses Zerreißen dadurch, daß zwei dünne, nur einseitig mit Tonaufzeichnungen versehene, fertig ausgepreßte Schallplatten (-hälften) aus durchsichtigem thermoplastischem Material nach Zwischenlegen einer doppelseitig oder zweier einseitig bedruckten Bildeinlagen oder von aus Papier oder anderen Werkstoffen, z. B. Aluminiumfolien, ausgestanzten Schattenrissen, die Bezug auf die Tonaufzeichnungen der jeweiligen Schallplattenseiten (-hälften) haben, auf der ganzen Fläche oder nur an den Rändern und dem Mittelloch mit Hilfe von farblosen Klebstoffen zusammengeklebt, mittels dielektrischer Erwärmung durch Hochfrequenzgeneratoren verschweißt oder schließlich durch eine zweite Pressung am Rande zu einer doppelseitig abspielbaren Schallplatte verbunden werden.The present invention avoids this rupture in that two thin, fully pressed records with sound recordings on only one side (halves) made of transparent thermoplastic material after inserting a double-sided or two single-sided printed picture inserts or made of paper or other materials, e.g. B. aluminum foils, punched out silhouettes, the reference on the sound recordings of the respective record sides (halves) the whole area or only on the edges and the central hole with the help of colorless Adhesives glued together, by means of dielectric heating High-frequency generators welded or finally by a second pressing be connected at the edge to a double-sided playable record.
