The spacing of the gaps is preferably as short as possible and the length of the direction is short. To the long sheet 5 along the line 4, the effect of this money is to supply the electric mineral liquid: the internal space of the frame 'and the plating solution is mixed with the 曰 = branch, by spraying from the top of the material 5 downward : The material 5 floats, so that the lower side is pressed against the line 4. Secondly: = the effect of the pouring of the long sheet 5 ~, the anti-negative sheet 5 is substantially vertical! 298358 posture, due to the long sheet 5 It is located at the approximate center of the electric money jet and is substantially parallel to the jet flow direction, so it can be applied from the electric money jet with approximately equal stress:: two sides of the long piece + material 5. However, when the long piece 5 is in the jet A slight tilt "flow" changes, and as a result, the pressure for correcting the tilt direction is applied from the key jet to the long sheet 5. Thereby, it is possible to prevent the long sheet 5 from being tilted and to supply the plating liquid inside the support frame 6 from the grooves 6a and 讣 of the support frame 6. The plating solution that has flowed out is recovered in a management tank (not shown) and supplied to the plating liquid supply pipe 15. #山社+ ’ As described above, by circulating the plating solution, the long sheet 5 and the anode 1 are held in the plating solution. By this, the DC energy is applied between the anode 10 and the long piece #5, and is dissolved in electricity (4): the ions of the plated metal are deposited on the surface of the long sheet 5. Anode J. The electro-mineral metal is replenished to the anode casing by the accompanying dissolution in the electro-recording liquid. At the position yb on the eve of the electric clock slot 1, a long sheet of the vertical posture is placed between the guide rods 7 to be loaded on the line 4, although it can be hand-worked, but it can also be pulled out of the field.卞蒹 Although ^ ^ ^ w . Straw is carried out using automatic equipment of various known mechanisms. The operation of taking out the electroplated sheet 5 by electric sputum is also carried out, and the line can be transported to the 3k line in the other slots of the first step before and after the electroplating step. For example, the pre-plating treatment (four) has flaws, and the post-treatment steps are neutralization, washing, and 妒 ^ ^ first electric key treatment (for example, the bottom plating is two.

The winding operation of the wire 4 is performed by the = winding one-winding device 29. In Fig. 4, the intermediate structure of the guide groove 20 in the processing tank 20 is omitted. In the present embodiment, the pulley 9 (see Fig. 2(b)) fixed to the lower portion of the pair of guide bars 7 and supported by the cooling means is preferably slightly one. . The resin is formed so that the elastic force can be continuously applied to the wire 4. Alternatively, a spring-loading mechanism is used which applies a spring force in a direction in which the pair of guide bars 7 and the sliding gap are shortened by using a spring or the like. Between I298358 ^ Further, when the thread 4 is taken up on the bobbin, in order to make the line 4 travel at a constant speed, it is easy to control, and a line drive mechanism using a pinch roller may be additionally provided. That is, the pinch rolls that are held at a constant speed by the wire are set by the position "after the plating tank", and the Μ is made of a relatively small torque winding line which does not cause slack in the line. In addition, only the % L is used instead of taking the wire on the bobbin, and an endless loop can also be formed, so that the wire passes through the outside of the plating tank and returns from the exit of the plating tank to the inlet. Further, in the above embodiment, the metal wire member is used as an example of a wire, but the metal t is not necessarily used. As long as there is a line of appropriate conductivity, the moon 匕 passes this line to a negative voltage on the long sheet. In the present invention, the so-called line, which is a wide range of wires, is comprehensive. Furthermore, "the need to reduce the loss of electroplated metal to minimize the replacement of the wire, etc., is preferably the use of a wire that is not easy to apply. Further, if the line "coated with Ni plating" on the Cu wire is used, the Cu material can be prevented from being eluted to the electro-recording liquid to reduce the maintenance work.

Further, as shown in Fig. 2(c) or Fig. 3(b), it is also possible to cover the region other than the portion with the groove portion 17 or the flat portion 18' of the exposed line 4 by the heat-reducing insulating member 19. Thereby, it is possible to suppress the unnecessary electroplating deposition 1 of the line 4 from being prevented from wasting the plating solution, and the maintenance work can be reduced. The heat-resistant insulating member 19' is preferably made of polyvinyl chloride having heat resistance. Further, if a metal wire is used as the wire 4, a rolling roller (not shown) having a ridge can be provided in the loading device 24 and the unloading device f 25 for forming the groove portion 17 and capable of forming the groove portion 17 The plating process is performed while forming the groove portion 17.
