In a fibrous filter element in which there are a bundle of fibres having woven edges supported around an inner support such as a cylinder and attached between two end supports the woven edges of the bundle of fibres are encapsulated with the end support with an encapsulating resin, this avoids the packing density of the fibres at the end of the element being reduced compared to that at the centre of the element and makes for easier handling and manufacture. |
