摘要： A tool device and its use for manufacturing a bicycle rim, having opposite rim flanks, a rim well and a rim base and rim flanges configured on the radially outwardly ends of the rim flanks, wherein the tool device includes two molding devices and a circular device. The circular device forms the rim well and the axially inwardly oriented surfaces of the rim flanges. The circular device includes an annular unit of a less elastic material and at least one cover of a more elastic material. Alternately, the molding devices each include a molding unit of a less elastic material and at least one cover of a more elastic material, for attachment thereto. The thickness of the cover is between one eighth of the minimum wall thickness of the rim well of the rim manufactured and eight times the minimum wall thickness of the rim well of the rim manufactured.

摘要： A method of manufacturing a fibrous composite bicycle rim , employs a tool device having a plurality of tool components including two molding devices and one circular device. The two molding devices each have one rim flank contact surface. The circular device includes a rim well contact surface. Tool components are provided, and a first varnish coat is applied to a rim contact surface and is dried. A first fiber layer of the fibrous composite material is applied to the flank contact surface of the molding devices, forming the outer fiber layers of the pertaining rim flanks. At least one first fiber layer of the fibrous composite material is applied to the circular device which forms the rim well. The tool components of are interconnected, and the tool device is closed, is heated up, and the smooth varnish coat firmly bonds with the hardening fibrous composite material.
