PURPOSE:To certainly prevent the wire cut and winding deflection of an extremely thin wire by feedback-operating the tension of the extremely thin wire on a tension transmitting lever which is electrically measured by a tension detector into a tension generator. CONSTITUTION:An extremely thin wire 1 supplied from a driving-out spool 6 is applied with a tension through an tension transmission spool 5 and a tension applying pulley 2 by a tension generator 10, and taken up onto a taking-up spool 15 through a processing device 20. The processing speed is control led by a driver 15 and a motor 16, with a deviation between the output of a taking up speed setting device 19 and the output of a taking-up tachogenerator 17. Further, the driving-out speed of the extremely thin wire 1 is control led similarly by a driver 9, and corrected by the output of a tension applying pulley position detector 3. The tension is detected as the strain of the tension transmitting lever 5 by a tension detector 13, and compared with the output of a tension setting device 11 through a conversion amplifier 14 by a driver 12, and control led by the tension generator 10. Thus, the wire cut and winding deflection can be certainly prevented. |
