Abstract: A nonwoven fabric is constructed of a highly flat glass fiber which is a glass fiber whose section is flat and has a flatness ratio of 2.0 to 10 and which has such a section that the packing fraction is at least 85%, preferably at least 90%. In this nonwoven fabric, the glass fiber section has a shape near rectangle, and hence, the glass fibers can be arranged very densely to form a thin nonwoven fabric having a high bulk density, and when it is used as a laminate material, the glass fiber content can be increased and the surface smoothness can simultaneously be enhanced and can be used appropriately as a reinforcing material for a printed wiring board. Moreover, the above flat glass fiber can be produced by use of, for example, a nozzle having such a shape that one side of the major axis walls of a nozzle chip having a flat nozzle hole is partly notched.

Abstract: Apparatus for reciprocating a yarn guide to wind yarn on a bobbin including a rotating scroll cam provided with an endless helical cam groove and a second cam groove in superposed relationship with the endless cam groove and having a greater lead angle than the endless cam groove over a predetermined distance adjacent each turning point. The yarn guide is provided with an elongate ship-shaped cam follower slidably fitted into the endless cam groove and pivotable with respect to the yarn guide and a cylindrical cam follower slidably fitted into the second cam groove. The width of the portion of the endless cam groove adjacent each turning point is gradually increased toward the turning point so as to permit the elongate cam follower to smoothly reverse its direction when it passes the turning point.

Abstract: A nonwoven fabric constituted of high--flatness glass fibers whose cross sections have aspect ratios of 2.0 to 10 and rates of filling of 85 % or above, preferably 90 % or above. Such glass fibers have nearly rectangular cross sections and therefore can be arranged in an extremely dense state to give a nonwoven fabric which is extremely thin and has a high bulk density. The fabric can give laminates which are enhanced in the glass fiber content and improved in the surface smoothness, thus being suitably usable as the reinforcement for printed wiring boards. The glass fibers can be produced by the use of, e.g., a nozzle equipped with a tip which has a flat orifice and whose major-axis wall is partially cut out on one side.
