Patent number: 6071460Abstract: An improved apparatus for manufacturing a reinforced golf club shaft having a complex shape. An inflatable bladder is positioned over a mandrel having a simple shape. Layers of fiber material are then rolled over inflatable bladder to produce a sub-assembly. The sub-assembly is placed in a mold defining a negative of the shape of the final shaft that is to be produced. The impression may have enlarged or narrowed regions for producing irregularities in the shape of the shaft. The bladder is expanded within the mold so that the composite structure is radially displaced and compressed between the bladder and the mold. The inflatable bladder has a variable thickness that conforms to the shape of the impression so that the composite structure undergoes a uniform and minimum displacement along its entire length, which improves the mechanical properties of the final shaft.Type: GrantFiled: August 15, 1997Date of Patent: June 6, 2000Assignee: Taylor Made Golf Company Inc.Inventors: Jean Pierre Renaudin, Philippe Renard

Patent number: 5002598Abstract: The application discloses an apparatus and a process for the manufacture of continuous fibers by mechanical attenuation. It is especially useful in obtaining a strand composed of a mixture of filaments of differing cross sections in constant and definite proportion. This is obtained by employment of a bushing having a lower surface comprising a multiplicity of fiberizing centers of varying configurations, each fiberizing center being formed by a zone perforated by a group of orifices from which at least one filament can be attenuated in a stable manner. The strands produced are particularly adapted for the reinforcement of plastic materials.Type: GrantFiled: January 6, 1989Date of Patent: March 26, 1991Assignee: Societe Vetrotex Saint-GobainInventors: Jacques Lecron, Maxime Manera, Jean-Paul Faure, Jean-Pierre Renaudin

Patent number: 4473387Abstract: Apparatus for the manufacture of thermoplastic mineral fibers is disclosed.A bushing base is formed by a flat plate in which a multitude of conduits are arranged. The upper ends of the conduits open toward the inside of the bushing and their lower ends toward a multitude of small alveoles, each alveole being in communication with the inside of the bushing by means of one of the said conduits. A continuous flat wall closes the base of each alveole, the said wall being perforated by several orifices forming a grouping of orifices.Type: GrantFiled: October 20, 1983Date of Patent: September 25, 1984Assignee: Societe Vetrotex Saint-GobainInventors: Jacques Lecron, Maxime Manera, Jean-Paul Faure, Jean-Pierre Renaudin

Patent number: 4469499Abstract: A process and apparatus is disclosed for forming fibers from attenuable materials, such as molten glass, by attenuating streams of glass from the bottom of a bushing wherein the bottom has downwardly presented wall portions at upper and lower levels. According to the disclosure the upper or lower wall portions are formed into series of bosses, each having a multiplicity of orifices in the lower ball portions. Bosses with alveoles are disclosed. Filamentary material is manufactured by drawing at least one filament from each boss independently of each other boss or from separate fiber forming regions in each boss regardless of whether or not the material has flooded the bottom surface of any boss. Embodiments with one alveole per boss or plural alveoles per boss are disclosed. Where plural alveoles per boss are provided, shallow transverse grooves in the lower wall portions of the bosses may be used to separate the orifices of one alveole from the orifices of adjacent alveoles.Type: GrantFiled: May 3, 1983Date of Patent: September 4, 1984Assignee: Societe Vetrotex Saint-GobainInventors: Jacques Lecron, Maxime Manera, Jean-Paul Faure, Jean-Pierre Renaudin

Patent number: 4401451Abstract: The application discloses an apparatus and a process for the manufacture of discontinuous fibers obtained by fluid attenuation. The fibers are attenuated from a bushing whose base is equipped with a substantially continuous plate having a hollowed upper surface of alveoles, said alveoles being perforated with orifices, and whose lower side is cut with grooves defining bosses, each boss being provided with one or several alveoles. The fibers produced are particularly adapted for use in the form of mat, sheet or roving.Type: GrantFiled: March 3, 1982Date of Patent: August 30, 1983Assignee: Societe Vetrotex Saint-GobainInventors: Jacques Lecron, Maxime Manera, Jean-Paul Faure, Jean-Pierre Renaudin

Patent number: 4398933Abstract: A process and apparatus for forming fibers from attenuable materials, such as molten glass, by attenuating streams of glass from the bottom of a bushing wherein the bottom has downwardly presented wall portions at upper and lower levels. According to the disclosure the upper or lower wall portions are formed into a series of elongated bosses each containing at least one row of cells termed alveoles, each alveole having a multiplicity of orifices extending through the lower wall portion of its boss. Filamentary material is manufactured by drawing at least one filament from each alveole independently of each other alveole regardless of whether or not the material has flooded the bottom surface of any boss. In one embodiment shallow transverse grooves in the lower wall portions of the bosses separate the orifices of one alveole from the orifices of adjacent alveoles so that flooding is confined to a single alveole.Type: GrantFiled: May 3, 1982Date of Patent: August 16, 1983Assignee: Societe Vetrotex Saint-GobainInventors: Jacques Lecron, Maxime Manera, Jean-Paul Faure, Jean-Pierre Renaudin
