摘要： PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a glass fiber, where molten glass with a constant heat is supplied to a spinning furnace, an inclusion of air does not occur, and a problem caused by an air bubble present in the glass fiber is controlled. SOLUTION: The temperature of a melting furnace 20 and the temperature and viscosity of the molten glass 3 feed from the melting furnace 20 to a spinning furnace 7 are maintained at a constant level without fluctuation of the quantity of the molten glass in the spinning furnace 7 by controlling a feed of the molten glass 3 to the spinning furnace 7 by opening and shutting or controlling the opening of a flow outlet 24 set at the bottom of the melting furnace 20 using a valve 25 installed at the flow outlet 24. The molten glass 3 is supplied to the spinning furnace 7 by flowing down along a rod-like guide 28 connected to the lower end of the body 26 of the valve 25. The molten glass 3 in flowing down does not swirl and is supplied into the spinning furnace 7 in a state maintaining a homogeneous temperature, where air is not involved in the molten glass 3.

摘要： PROBLEM TO BE SOLVED: To provide a traverse guide for winding a fiber bundle capable of winding up a fiber bundle of e.g. glass fiber without causing any twisted portions in the bundle for resultantly forming a package. SOLUTION: This traverse guide 20 for winding up a fiber bundle 14 comprises; a slit 24 for allowing the bundle 14 to pass therethrough; a constrainer plane 26 for constraining the bundle 14 having gotten through the slit 24; and a space section 25 formed between the slit 24 and the constraining plane 26 for allowing the bundle 14 to twist at an angle of about 90 degrees without any constraint. In the space section 25, an unequal force tending to disarrange the alignment of filaments forming the bundle 14 is absorbed because each filament itself moves in a proper manner within the space section 25. Hence, the bundle 14 is wound up around a package P while remaining in a flat state independent of any disarrangements, twists or the like in the alignment of the filaments.

摘要： PROBLEM TO BE SOLVED: To provide an inorganic fibrous ceiling board hard to make the dew condensation inside an inorganic fibrous board and capable of maintaining sound absorption efficiency and heat insulating efficiency even when the inorganic fibrous ceiling board is constructed in such a structure as the indoor side becomes high temperature and high humidity. SOLUTION: A waterproofing film 2 having over 50m .hr.mmHg/g of vapor resistance is stuck on the surface placed to the indoor side of an inorganic fibrous board 1 with an adhesive 3. The surface placed on an attic space side of the inorganic fibrous board 1 is covered with a waterproofing film 4 having vapor resistance less than 1/5 of vapor resistance of the waterproofing film 2. The waterproofing film 2 on the indoor side and waterproofing film 4 on the attic space side are connected at those circumferential edge sections, and the circumference of the inorganic fibrous board 1 is completely covered to constitute a ceiling board.

摘要： PROBLEM TO BE SOLVED: To form a package by winding a fiber bundle of glass fiber, etc., without twisting it. SOLUTION: A traverse guide 20 to be used to wind up a fiber bundle 14 is furnished with a slit 24 to pass the fiber bundle 14, a guide surface part 25 to be positioned at both sides of the slit 24 and a constraint surface part 26 to constrain the fiber bundle 14 passing through the slit 24 positioned below them. As a bottom part 24a of the slit 24 and the guide surface part 25 have a curved surface shape, movement of the fiber bundle 14 at the bottom part 24a and movement of a sliding position of the fiber bundle 14 and the guide surface part 25 caused in accordance with reciprocating motion of the traverse guide 20 in the axial direction of a package P are extremely smoothly carried out. Consequently, the fiber bundle 14 winds around the package P while keeping a flat state not causing turbulence, twisting, etc., of arrangement of filaments not only in the middle of movement of the traverse guide 20 but also in the case of reversing the moving direction.

摘要： PROBLEM TO BE SOLVED: To obtain a blended yarn for composite materials in which continuous reinforced fiber bundles and continuous thermoplastic-resin fiber bundles are uniformly mix-spun, and to provide a method of its production. SOLUTION: This blended yarn for composite materials is obtained by subjecting continuous reinforced fiber bundles 12a of no twist and continuous thermoplastic-resin fiber bundles 22a of no twist to opening processing to produce opened continuous reinforced fiber bundles 12b and opened continuous thermoplastic-resin fiber bundles 22b both of which have 0.5-3 of the opening factor defined by formula: F=W/DN (F is an opening factor; W is width of a fiber bundle (mm) when measured in the rolled condition in the case of rolled yarn or in the condition of the bundle at the outlet of an opening machine in the case of a bundle immediately after opening, D is a diameter of single fibers (mm), N is number of single fibers in a fiber bundle), and then mix- spinning the opened continuous reinforced fiber bundles 12b and opened continuous thermoplastic-resin fiber bundles 22b.
