Abstract (en)
1. An apparatus for the sound insulating closure of the opening of a machine housing, said opening being provided for the delivery and removal of material being processed in said machine, characterized in - that a flexible mat (18, 36, 136, 236) or the like is disposed within said opening (16, 34), said mat overlapping said opening and resting with a rim portion (20, 38, 138, 238) against the housing wall (22, 40, 140, 240) defining said opening ; - that at least said rim portion (20, 38, 138, 238) is magnetically polarized ; and - that said housing wall (22, 40, 140, 240) associated with said rim portion (20, 38, 138, 238) includes means (26, 42) which are able to take selectively a polarization which is equal with or neutral, or opposite, respectively, to the polarization of said mat (18, 36, 136, 236).
Abstract (de)
Die Öffnung (16, 34) eines Maschinengehäuses ist zur Schallabdichtung mit einer flexiblen Matte (18, 36) abgedeckt, die mindestens in einem Randbereich magnetisch polarisiert ist. Die unter dem Randbereich liegende Gehäusewand (22, 40) ist mit zur Polarisierung der Matte gleichsinnig oder gegensinnig bzw. neutral polarisierbaren Elementen (26, 42) versehen. Die Polarisierung dieser Elemente erfolgt abhängig vom Betriebszustand von in dem Maschinengehäuse angeordneten Einrichtungen.
