Abstract

Uppfinningen avser ett filtermagasin (1, 2) for en filtersubstans. Filtermagasinet har ett ramparti (2) med öppningar täckta med ett membran (1). Membranet är ihopgjutet med rampartiet sånär som på över öppningarna och membranet är försträckt i öppningarna. Detta förebygger att membranet buktar ut och lämnar utrymme för luckor i filtersubstansenEtt sätt att uppnå försträckningen på är om membranet har en högre värmeutvidgningskoefficient än ramen.Uppfinningen avser därtill en metod att tillverka sådana filtermagasin (1, 2). Rampartiet (2) formas i icke fast tillstånd tillsammans med membranet till ett sammanhängande fast element, där membranet är försträckt i öppningarna. Membranet kan sträckas medan rampartiet övergår i fast form och denna försträckning kvarstår sedan.The invention relates to a filter magazine (1, 2) for a filter substance. The filter magazine has a frame portion (2) with openings covered with a membrane (1). The diaphragm is cast together with the frame portion except on the openings and the diaphragm is stretched in the openings. This prevents the membrane from bulging out and leaving space for gaps in the filter substance. One way to achieve the pre-stretching is if the membrane has a higher coefficient of thermal expansion than the frame. The invention also relates to a method of manufacturing such filter magazines (1, 2). The frame portion (2) is formed in the non-solid state together with the membrane into a continuous solid element, where the membrane is stretched in the openings. The membrane can be stretched while the frame portion changes to a solid form and this pre-stretching then remains.
