PURPOSE:To give tension to a fine wire very inexpensively by mounting to a delivery side flange of a bobbin in the peripheral direction an elastic cord giving by its flection the tension to the fine wire delivered while it is brought into contact with the elastic cord. CONSTITUTION:For instance, when two or more fine wires (a) are delivered to a collector, in each bobbin of the fine wire (a), it is delivered while turning around a flange 10 as shown by full-line chain-line, and the fine wire, as it turns around, comes into contact with and separates from elastic cords 12 provided in the flange 10 in the radial direction. At the time of these contact and separation, the elastic cord 12 is flexed as shown by the chain-line, so that the fine wire (a) is given fixed tension by elastic force of the elastic cord 12. By the constitution thus giving the tension to the fine wire (a) by the elastic cord 12, a device can be formed inexpensively.
