Abstract
A papermaking mold 10 includes a mold main body 10A having a wire part and a wire 108 disposed on the wire part. The wire part has a base surface 102, a columnar projection 106 lying sideways on the base surface 102, and at least two plate-like projections 105 at predetermined positions at a predetermined spacing in the longitudinal direction of the columnar projection 106. The facing inner sides 105A of every adjacent two of the plate-like projections 105 are each formed of a part of a circular conical surface or a part of a hyperboloid.
Claims22
A papermaking mold comprising a mold main body having a wire part and a wire disposed on the wire part, the wire part having a base surface, a columnar projection having a longitudinal direction and lying sideways on the base surface, and at least two plate-like projections at predetermined positions at a predetermined spacing in the longitudinal direction of the columnar projection, the facing inner sides of every adjacent two of the plate-like projections being each formed of a part of a circular conical surface or a part of a hyperboloid.
A fiber molded article having a flange, the fiber molded article comprising a base plate inclusive of the flange, a columnar projection having a longitudinal direction, and at least two plate-like projections at predetermined positions at a predetermined spacing in the longitudinal direction of the columnar projection, the facing inner sides of every adjacent two of the plate-like projections being each formed of a part of a circular conical surface or a part of a hyperboloid.
A casting mold part having a base surface and a cavity that is concave relative to the base surface and forms a molding surface to produce a casting having a plurality of plate-like parts at a predetermined spacing, wherein the cavity has a plurality of depressions for forming plate-like projections spaced face-to-face in a prescribed direction, the adjacent inner sides of every adjacent two of the depressions for forming plate-like projections being each formed of a part of a circular conical surface or a part of a hyperboloid.
