    Abstract: A molding device is includes a mandrel that has an arc-shaped cross section; a roller that has a round-shaped cross section, is movable along a surface of the mandrel, and applies a pressing force to a material to be molded placed on the mandrel; a gripping unit that grips the material to be molded on an outside of the roller with respect to the mandrel and applies a tensile force to the material to be molded; a roller driving unit that moves the roller along the surface of the mandrel; a gripping-unit driving unit that moves the gripping unit. A control unit synchronizes a position of the roller and a position of the gripping unit with each other to control the roller driving unit and the gripping-unit driving unit so that the material to be molded is arranged in a direction perpendicular to a vertical direction of the mandrel.

    Abstract: A method of manufacturing a composite structure includes providing a mandrel comprising a base part and at least one conical part. The base part comprises an elongate shaft. The base part of the mandrel comprises a cylindrical surface around a longitudinal axis of the base part. The at least one conical part extends from the cylindrical surface of the base part. The mandrel and a braiding machine are moved relative to one another such that fibre tows are braided over at least the base part of the mandrel. The mandrel and the braiding machine are arranged such that during the braiding process, none of the fibre tows intersect with a vertex of the at least one conical part of the mandrel.

    Abstract: A method for manufacturing a high pressure tank includes a step of forming a reinforcing pipe portion including a straight pipe portion and reduced-diameter portions, a step of forming reinforcing dome portions, a step of forming a joined body by joining the reinforcing pipe portion and the reinforcing dome portions, and a step of forming an outer helical layer on an outer face of the joined body. The reinforcing dome portions are disposed with opening ends of the reinforcing dome portions positioned on outer faces of the reduced-diameter portions of the reinforcing pipe portion.

    Abstract: A balloon wrapping apparatus and a balloon wrapping method are disclosed by which a balloon can be wrapped appropriately. The balloon wrapping apparatus for wrapping a balloon of a balloon catheter provided with the balloon at a distal portion of an elongated shaft includes: a pleating section that forms the balloon with wing shapes projecting in radial directions; a folding section that includes a plurality of blades aligned in a circumferential direction, and that folds the wing shapes formed in the balloon along the circumferential direction by moving rotationally the blades; and a rotational support portion that supports a portion of the shaft which portion is on a proximal side of the balloon, and that rotates the shaft in a direction opposite to a rotary movement direction of the blades in a state in which the balloon is positioned in relation to the folding section.

    Abstract: In an embodiment, a paint roller manufacturing system and method uses a fabric-coating applicator to apply a fabric adhesive onto a portion of a perforated paint roller cover fabric material having a plurality of perforations through which adhesive may flow, and into the plurality of perforations and into interstitial spaces of the fabric material, to yield a length of coated fabric. An inner strip and an outer strip are wound about a mandrel in offset relation. A strip-coating applicator is used to apply a strip adhesive to the outer strip as it is wound about the mandrel. Simultaneously with the step of applying the strip adhesive to the outer strip, a portion of the coated paint roller fabric material is received at the outer strip and the length of coated fabric is wound about at least the outer strip to form a paint roller tube.
