Description

上記目的を達成するため、請求項１〜５記載の発明は、ジグザグ形状に折り加工した濾材の端部を接合して中空円筒状に形成して筒状プリーツ濾材とした後、前記筒状プリーツ濾材の両端面にリング状のエンドシートを取り付けるフィルタエレメントの製造方法において、
前記筒状プリーツ濾材の外周側に配置する外側治具と前記筒状プリーツ濾材の内周側に配置する内側治具との間に前記筒状プリーツ濾材を挟み込み、この状態で前記筒状プリーツ濾材の両端面に前記エンドシートを接着剤を介して接合することを特徴とするフィルタエレメントの製造方法をその要旨とした。
In order to achieve the above-mentioned object, the inventions according to claims 1 to 5 are characterized in that the cylindrical pleat filter medium is obtained by joining the ends of the filter medium folded into a zigzag shape to form a hollow cylindrical pleat filter medium. In the method for manufacturing a filter element in which ring-shaped end sheets are attached to both end faces of the filter medium,
The cylindrical pleat filter medium is sandwiched between an outer jig arranged on the outer peripheral side of the cylindrical pleat filter medium and an inner jig arranged on the inner peripheral side of the cylindrical pleat filter medium, and the cylindrical pleat filter medium in this state The gist of the filter element manufacturing method is that the end sheets are joined to both end faces of the substrate through an adhesive.

また、請求項６記載の発明は、ジグザグ形状に折り加工した濾材の端部を接合して中空円筒状に形成して筒状プリーツ濾材とした後、前記筒状プリーツ濾材の両端面にリング状のエンドシートを取り付けるフィルタエレメントの製造に使用する治具であって
前記筒状プリーツ濾材の外周側に配置する変形可能な外側治具と前記筒状プリーツ濾材の内周側に配置する変形可能な内側治具とからなり
前記外側治具と内側治具との間に前記筒状プリーツ濾材を挟み込んで該筒状プリーツ濾材の形状を固定し、この状態で前記筒状プリーツ濾材の両端面にエンドシートを接着剤を介して接合した後、前記外側治具及び内側治具を変形させることにより前記筒状プリーツ濾材の内側と外側とから前記外側治具及び内側治具を取り外すことができるようにしたことを特徴とするフィルタエレメントの製造用治具をその要旨とした。
Further, in the invention of claim 6, after joining the end portions of the filter medium folded into a zigzag shape to form a hollow cylindrical shape to form a cylindrical pleated filter medium, ring-like shapes are formed on both end faces of the cylindrical pleated filter medium. A jig used for manufacturing a filter element to which an end sheet is attached, which is a deformable outer jig disposed on the outer peripheral side of the cylindrical pleated filter medium and a deformable jig disposed on the inner peripheral side of the cylindrical pleated filter medium. The cylindrical pleat filter medium is sandwiched between the outer jig and the inner jig to fix the shape of the cylindrical pleat filter medium, and in this state, ends are formed on both end faces of the cylindrical pleat filter medium. After joining the sheet via an adhesive, the outer jig and the inner jig can be removed from the inside and outside of the tubular pleat filter medium by deforming the outer jig and the inner jig. The prepared jigs of the filter element, characterized in that the set to its gist.
