    • PROBLEM TO BE SOLVED: To provide a yarn winder capable of suppressing the generation of a growth ring and the occurrence cob-webbing by changing a control method for a traverse width in an accelerated winding zone flexibly according to, for example, a yarn winding method.
      SOLUTION: An automatic winder comprises a package drive motor 41, a traverse drive motor 45, and a traverse width shortening part 63. The traverse drive motor 45 drives a traverse guide 11 for traversing a yarn 20 wrapped around a winding bobbin 22 rotated by the package drive motor 41 so as to reciprocate. The traverse width shortening part 63 comprises a shortened width constant mode in which the traverse drive motor 45 is so controlled that a traverse is performed in the accelerated winding zone in a constant shortened traverse width smaller than the target traverse width according to the initial traverse width set by a setter 51 and a shortened width changing mode in which the traverse drive motor 45 is so controlled that a traverse is performed in a traverse width continuously increased from the shortened traverse width when a winding speed is increased.

    • PURPOSE:To facilitate changing of each setting by driving a traverse through reciprocal motion of a linear motor then setting the speed pattern of the linear motor and the moving stroke of the traverse bar electrically. CONSTITUTION:The speed pattern setting section 2 will set the desired speed pattern to feed the acceleration (a), steady speed (v) and motion stroke (S) command to the linear motor drive section 3. Said section 3 will drive the linear motor 4 on the command from a start switch 6. The linear motor 4 will drive the movable section 4b on the basis of the given speed pattern to reciprocate the traverse bar linearly. Consequently a plurality of strings 8 passed through the string guide 7 are traversed to move the winding position against the rotating bobbin 9. Here said speed pattern is set electrically to facilitate changing thus to perform proper traverse motion.

    • PROBLEM TO BE SOLVED: To provide a method and a device for assembling a large number of optical fibers with which it is possible for fiber bundles to be produced and assembled from a large number of individual fibers while maintaining the quality requirements. SOLUTION: A device for assembling a large number of synchronously produced individual optical fibers comprises a drawing installation for drawing a plurality of fibers and a take-up winder for winding a plurality of fibers on a take-up spool. The drawing installation provides an identical and constant drawing rate for each of the fibers. The take-up winder has a correcting device to correct for differences in speed of the fibers between the drawing installation and the take-up spool. The fluctuations of the fiber diameter during the production of the fibers are avoided and a plurality of fibers are sent at a substantially constant rate to the take-up winder. The fiber bundle can be assembled without influencing the drawing rate, and thereby also avoiding action on a melting process when drawing the fibers from a heated preform.
