    • PROBLEM TO BE SOLVED: To improve the quality of a doubled yarn formed just after the start of operation, and to prevent yarn break just after the start of the operation by forming a balloon of an outer yarn in early stage.
      SOLUTION: A tension-imparting device 5 for imparting the tension to the outer yarn Y2 is installed. The tension-imparting device 5 is constituted so as to enable to change the tension to be imparted to the outer yarn Y2. A tension control part 51 for controlling the tension-imparting device 5 is also installed so that a tension smaller than the tension to be imparted to the outer yarn Y2 at normal operation may be imparted to the outer yarn Y2 during the period from the starting time of the operation to the time after passing a prescribed time.

    • 要解决的问题:为了提高刚刚开始运转之后形成的双纱的质量,并且通过在早期形成外纱的气球来防止在开始操作之后的断纱。

      解决方案:安装用于向外纱线Y2施加张力的张力赋予装置5。 张力赋予装置5构成为能够改变赋予外线Y2的张力。 用于控制张力赋予装置5的张力控制部51也被安装成使得可以在从开始时间起的时间期间向外纱线Y2施加小于在正常操作时赋予外纱线Y2的张力的张力 经过规定时间之后的时间。 版权所有(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a tension device capable of controlling the tension of a thin wire rod in a careful manner.
      SOLUTION: When an air pressure source 150 feeds air into an air chamber 133e through a hose H and a connector C, the air is supplied to a through hole 141 of a cylindrical hollow member 140 only through opening upper inclined holes 142 since lower inclined holes 143 are closed by an inner surface of a stage 133x, which provides an upward gas flow in the through hole 141 (as shown in Fig.2). Thereafter, releasing the wire rod W by a cutting and holding mechanism and rotating a rotation shaft 122 causes the wire rod W to be wound around an outer circumferential surface of a bobbin B. On this occasion, the wire rod W passing through the through hole 141 receives a resistance by the upward air flow, with a desired tension applied thereto.

    • 要解决的问题:提供能够小心地控制细线材的张力的张力装置。 解决方案:当空气压力源150通过软管H和连接器C将空气进入空气室133e时,仅通过打开的上倾斜孔142将空气供应到圆柱形中空构件140的通孔141,因为 下倾斜孔143由台133x的内表面封闭,该内表面在通孔141中提供向上的气流(如图2所示)。 此后,通过切割保持机构释放线材W并旋转旋转轴122使线材W卷绕在线轴B的外周面上。这时,线材W穿过通孔 141通过向上的空气流接收电阻,施加期望的张力。 版权所有(C)2008,JPO&INPIT
