摘要： A spinning apparatus for a fasciated yarn is provided which comprises a fiber-opening means provided with a combing roller, a fiber-collecting means including an inlet member and a rotor, a twist-imparting means consisting of an air nozzle, and a yarn take-up means. A sliver opened by the combing roller is fed to the interior of the rotor through the inlet member. Since the rotor and the inlet member rotate reversely to each other, the fibers are evenly distributed on an inner surface of the rotor. An intermediate yarn drawn out from the rotor is supplied to the air nozzle under an overfeeding condition, whereby a good fasciating effect is imparted to the resultant yarn by a vortex. Prior to feeding the yarn to the air nozzle, the yarn may be drafted between two pairs of rollers. The apparatus is easy to maintain because a roller drafting means having an apron which rapidly wears due to high-speed processing is not utilized.

摘要： A method of yarn piecing in a fasciated yarn spinning unit is disclosed by which a yarn having a broken end and drawn out from the yarn package is introduced through the false-twisting nozzle by conducting an intermediate portion of the yarn into a slit which is formed on a lateral side of the nozzle and extends to the yarn passage channel in the nozzle. Because the yarn has been previously cut into a predetermined length thereof, the cut end of the yarn is placed in the drafting zone of the drafting mechanism at a position where the cut yarn end overlaps a broken end of the fiber bundle. By restarting the spinning operation, the overlapping ends of the yarn and fiber bundle are drafted properly in the drafting zone and then the fibers in the overlapping ends are intermingled by the false-twisting effect of the rotary stream of jetted air while they are advanced through the false-twisting nozzle.

摘要： In the piecing operation, the broken ends of a yarn and a fiber bundle are sucked into a suction nozzle, and therein are entangled due to twists imparted to the fiber bundle by first vortices utilized for forming a fasciated yarn. The broken end of the yarn may be twisted in reverse of the fiber bundle by second vortices. Further, third vortices weaker than the first vortices may be used instead of the first vortices. The apparatus comprises jets for generating the second and third vortices and piping for transporting air to the jets and from the suction nozzle, as well as a control circuit thereof.

摘要： A bottom tenser utilized for a drafting means of a spinning frame, especially for fasciated yarn spinning, in which a fiber bundle is attenuated at a high speed exceeding 100 m/min. The bottom tenser as well as a bottom roller corresponding to the tenser is provided with a free end through which an apron is easily removable from and mountable on the tenser and the roller. The tenser may be constituted by a body and at least a guide wall movable relative to the body. The guide wall prevents lateral movement of the apron in its operative position and, in turn, is displaced or removed from the body in its non-operative position so as not to obstruct an apron exchanging operation.

摘要： A method and apparatus for spinning a modified fasciated yarn at a high production rate featuring a combination of open-end spinning and fasciated yarn spinning. A sliver is opened by a combing roller and deposited as a fiber layer on a fiber collecting surface of a drum rotor rotating at a high speed. Thereafter, the fiber layer is drawn off from the fiber collecting surface as a continuous fiber bundle by a central rotor rotating coaxially with the drum rotor at a faster speed. During the drawing-off operation, the fiber bundle is flattened to a ribbon form by making contact to a deflector and is subjected to a vortex within an air twisting nozzle mounted on the central rotor to form a resultant yarn. According to the present invention, high production rate can be obtained because a roller drafting system having aprons can be omitted.

摘要： An attachment lens is arranged in a stage subsequent to a scanning lens. After a laser beam is converged by the scanning lens, the laser beam is converted into a parallel beam by the attachment lens. When the scanning lens is displaced in a direction perpendicular to an optical axis of the laser beam, a traveling direction of the laser beam is bent by a predetermined angle immediately after the laser beam passes through the scanning lens. Then, the traveling direction of the laser beam is further bent by a predetermined angle in the same direction by the passage of the laser beam through the attachment lens. Accordingly, a final swing angle of the laser beam outgoing from an outgoing window is increased by a swing angle imparted by the attachment lens compared with the case where the attachment lens is not arranged. One of lens surfaces of the attachment lens is formed in a toroidal surface, which allows the laser beam to have a long outline in a vertical direction.
摘要翻译： 附着透镜布置在扫描透镜之后的阶段中。 在激光束被扫描透镜会聚之后，激光束被附着透镜转换成平行光束。 当扫描透镜在与激光束的光轴垂直的方向上移位时，激光束的行进方向在激光束通过扫描透镜之后立即弯曲预定角度。 然后，激光束的行进方向通过激光束通过附着透镜而沿相同方向进一步弯曲预定角度。 因此，与未配置附件镜头的情况相比，从出射窗口射出的激光束的最终摆动角度增加了由附着镜头施加的摆动角度。 附着透镜的透镜表面之一形成在环形表面中，这允许激光束在垂直方向上具有长轮廓。
