摘要: In a filter manufacturing method, during a time period from the start of the suction of the slurry to a point in time when fibers in the slurry accumulate on the outer peripheral surface of the protector to a prescribed thickness, the protector and its leg portions are held spaced away from each other. The leg portions are moved toward the protector so that the leg portions are disposed at a position spaced by a uniform distance from the outer peripheral surface of the protector and the suction operation is continued. Thus, the slurry containing the fibers therein can be easily caused to flow deeply into recess portions of a fin-like portion with no fiber being caught between the protector and the leg portions, thus reducing non-walled portions.

摘要: A filter element made of nonwoven filter fabric includes a plurality of pleated portions and a flange portion formed integrally with the filter portion. The flange portion is formed by a pair of press-forming dies to have a thin and compressed connecting portion formed along the outer periphery of the filter portion, a thick and uncompressed seal portion formed along the outer periphery of the connecting portion and a thin and compressed protecting portion formed along the outer periphery of the seal portion.

摘要: An apparatus performing a filter from a material for a filter element automatically and quickly. The filter made by the present apparatus has a plurality of wavy portions which are provided in such a manner that a plurality of wavy portions forms a circle.The apparatus employs a contracting apparatus for contracting a continuously corrugated strip of material for a filter element in such a manner that a distance between adjacent ridges of the corrugated strip is reduced so that the corrugated strip becomes the wavy portion of the filter. The apparatus also employs a rounding apparatus for rounding the continuously corrugated strip in such a manner that both ends of the strip are connected to each other so that the wavy portions made from the corrugated strip form a circle. The apparatus further employs a shaping apparatus for shaping the rounded continuously corrugated strip so that the rounded strip becomes the filter.

摘要: A filter element has a generally ring-like structure which basically comprises a plurality of generally radial sections circumferentially arranged to define a central space. Each radial section has a plurality of circumferentially zigzag pleats formed from a ribbon of a filtering sheet material. The radial sections are circumferentially connected such that radially inwardly open generally radial spaces and radially outwardly open generally radial spaces are defined. The radially inwardly open radial spaces are closed at the axially opposite ends by end walls. Fluid to be filtrated can enter the radially outwardly open radial spaces and then passes through the zigzag pleats into the radially inwardly open radial spaces and thus into the central space. The ring-like structure has many modifications.

摘要: The filter element of the present has a plurality of wavy portions which are so arranged that a plurality of wavy portions make a generally ring like structure. In order to reduce the pressure drop when the fluid flows through the filter element, the present filter element has a special shaped radial gaps. Namely, the width of a first radial gaps, which is formed within adjacent wavy portions and which connects with an inner space formed at the center of the generally ring like structure, increases from the outer end thereof to the inner end thereof. The width of a second radial gap, which is connected with outer atmosphere, decreases from the outer end thereof to the inner end thereof. Both axial ends of the wavy portions are covered with the adhesive sheet on which adhesive layer is cladded.

摘要翻译: 过滤器元件具有大致环形结构,其基本上包括周向布置以限定中心空间的多个大致径向部分。 每个径向部分具有由过滤片材料的带形成的多个周向Z字形褶皱。 径向部分周向连接,使得径向向内敞开的大致径向空间和径向向外敞开的大致径向空间被限定。 径向向内开放的径向空间在轴向相对端处由端壁封闭。 要过滤的流体可以进入径向向外开放的径向空间,然后通过Z形折叠进入径向向内敞开的径向空间,从而进入中心空间。 环形结构有许多修改。
