摘要： An air nozzle, suitable for producing a fasciated yarn, having at least one jet in each of narrow and wide passages along the traveling direction of the fiber bundle. Each jet is directed to generate a vortex whirling reversely from that of the other passage. The twist imparted to the fiber bundle by the vortex generated in the wide passage is restrained by the vortex whirling reversely thereto in the narrow passage. As a result, circumferential fibers of the fiber bundle are less twisted relative to the core portion thereof. During the untwisting operation of the vortex of the wide passage, the circumferential fibers are entangled around the core portion with a twist corresponding to the difference from the core portion, thereby obtaining a well-fasciated yarn.

摘要： A method and an apparatus for producing a fasciated yarn, utilizing an air nozzle for false-twisting a fiber bundle. The apparatus is provided with a fiber passage comprising an inlet portion, a small channel, and a large channel, and is provided also with a contact area on an inner wall of the small channel, this contact area being formed by the intersection at an angle of the small channel and the large channel.During the spinning operation, the fiber bundle is forced against the contact area, effectively suppressing a twist imparted by a vortex such that it does not ascend toward the upstream region.Also, since ballooning can be suppressed by the contact area, the size of the small channel can be increased, resulting in the intake by suction of a sufficient amount of air in the inlet portion.

摘要： Sliver weight unevenness correcting apparatus of a feed-forward type has: a sliver weight measuring section for detecting the variations in weight of a bundle of slivers; a correcting draft device having front rollers disposed downstream of the sliver weight measuring section relative to the direction of advancement of slivers, the front rollers being rotated at a constant speed, and back rollers disposed between the sliver weight measuring section and the front rollers, the back rollers being rotated at a variable speed; a rotation detector for detecting the number of revolutions of the front rollers; an unevenness correcting circuit having a ratio circuit for operating a ratio (E.sub.0 /E.sub.1) between a reference sliver weight (E.sub.0) and the detected weight (E.sub.1) thereof, a delay circuit for delaying the speed control of the back rollers of the correcting draft device for a predetermined period of time, and a contrasting operational circuit for multiplying the ratio (E.sub.0 /E.sub.1) and a ratio (N.sub.F /k) between the number (N.sub.F) of revolutions of the front rollers and a reference draft value (k) and for producing a multiplied signal (E.sub.0 /E.sub.1 .multidot. N.sub.F /k); and a speed control circuit for producing a speed control signal responsive to the multiplied signal to control the speed of back rollers through a rotation transmitting mechanism. This arrangement enables accurate correction of sliver weight unevenness even short in wavelength in a drawing frame running at a high speed.

摘要： A novel fiber drafting system is disclosed, according to which fibers of sliver supplied continuously are passed through a first pair of rotatable cooperating rollers while being pressed and compacted into a reduced section by and between a space formed by a groove and a projection formed respectively in and on the circumferential peripheries of the rollers of said first pair. The sliver thus compacted is then transferred to and held by and between a second pair of rollers rotated at a higher peripheral speed than the first pair of rollers, whereby the fibers of sliver are drafted successively between the two pairs of rollers without use of conventional aprons for guiding and supporting the fibers in the drafting zone.
