Abstract

Um ein Verfahren zur Herstellung von Schalldämpfereinsätzen sowie neuartige Schalldämpfereinsätze bereitzustellen, welche in Umfang und Gestalt dem Innenraum des zu füllenden Schalldämpfer-Gehäuses mit einfachen Mitteln möglichst optimal anpassbar sind, darüber hinaus wirtschaftlich herstellbar und in der Wirkung verbessert sind,. wird vorgeschlagen ein Verfahren zur Herstellung von Schalldämpfereinsätzen, welche ganz oder teilweise nach dem Absorptionsprinzip arbeiten, wobei eine vorgegebene Menge eines losen Gebindes aus Einzelelementen eines geeigneten Schallschluckmaterials gebildet wird, das lose Gebinde grob in ein der beabsichtigten Form des Schalldämpfereinsatzes entsprechendes Montage-Formelement ausgeformt. wird und wobei das lose Gebinde in der dem Montage-Formelement entsprechenden Form zu einem Formverbund fixiert wird, derart, daß die fixierte Form ohne Auflösung in Einzelelemente bis zur Montage zum bestimmungsgemäßen Einsatz des Schalldämpfereinsatzes handhabbar ist, jedoch während des bestimmungsgemäßen Einsatzes als Schalldämpfereinsatz die Fixierung wenigstens teilweise wieder aufgehoben wird.
