摘要： A filter element of the present invention provides low pressure loss, superior filter performance and bonding of filtering material, and compactness. An inlet path of a nearly semicircular configuration which is formed in the width direction of a filter element is open at its upper side and closed at its lower side. An outlet path is closed at its upper side and open at its lower side. Corrugated filtering material has continuous mountain portions and valley portions. The mountain portions have a large radius of curvature R1, and the valley portions have a small radius of curvature R2. The valley portions are bonded to a flat filtering material. The open surface area of the inlet path is larger than the closed surface area of the outlet path 16. Preferably, R1/R2 is set so as to be within the range of 1.5 to 3.0.

摘要： A method for manufacturing filter elements, in which sealant does not get onto the rolling claw and rolling of the roll filter paper is made easy.A long roll filter paper having laterally oriented filter parts for filtering, the filter parts being open on the inflow side of the roll filter paper and closed on the outflow side of the roll filter paper, is rolled. During rolling, a sealant is applied to the surface of the roll filter paper in a narrow longitudinal strip, in such a way that the sealant does not make contact with the rolling claw. The roll-start end of the roll filter paper is gripped with the rolling claw during rolling. The rolling claw is made up of 2 or 4 rolling bars having the shape of the parts produced when a cylinder is split into two halves along its axis.

摘要： A filter element has a wavy filter portion including a plurality of ridges of a filter material, which are juxtaposed to one another and closed at their sides, and a flange portion extending along a mounting plane around the filter portion for supporting the filter portion. The flange portion is made of the same filter material extending from the filter portion, by compressing the filter material more densely than the filter portion. The filter element is manufactured by a step of preparing an intermediate product of a wavy sheet, and a step of forming the filter portion by leaving the central portion of the wavy intermediate product as in the wavy sheet, and forming the flange portion around the filter portion for supporting the filter portion, by pressing the side portions of the ridges of the wavy intermediate product along the mounting plane.

摘要： A filter production method produces a filter having a shape substantially identical to the shape of a forming surface by extruding semi-molten fibers to the forming surface. When the semi-molten fibers are extruded to the forming surface, the semi-molten fibers are gathered to upstanding surface portions of the forming surface. Therefore, a sufficient amount of fibers can be layered onto the upstanding surface portions, so that the layering amount of fibers on the upstanding surface portions of the forming surface will not be considerably reduced in comparison with the layering amounts on other portions of the forming surface.

摘要： A seal member is attached to a peripheral edge portion of a filter body by being fused to semi-melted fibers that form the filter body when the semi-melted fibers are layered over a forming surface. Therefore, the formation of the filter body and the attachment of the seal member can be simultaneously accomplished.

摘要： A filter portion of a filter includes a plurality of bag-like members. The bag-like members are formed in a container shape having an opening and disposed with intervals therebetween. The periphery of the opening of each bag-like member is supported by a supporting member, and the bag-like members are mutually connected by the supporting member. Consequently, the strength of the filter portion comprising the bag-like members is improved.
