Abstract:
1. A roller rolling machine making a sheet electrode with a predetermined thickness for an electric double layer capacitor by carrying out a rolling step, said machine comprising: (a) A pair of rolling rollers; (b) a winding section for winding up the rollers; (c) a drawing section for drawing out the rollers; (d) a tension control device for controlling tension of a sheet drawn out of the drawing section so that the tension on the sheet is constant; (e) an edge position control device for controlling a widthwise position of the sheet, said edge position control device being located immediately before the rolling rollers; (f) a winding side drive roller located adjacent to the winding section so as to be rotated at a predetermined speed; and (g) a pressing element for applying a predetermined pressure to a drive roller on the winding side so that the winding section is pressed against the winding side drive roller.
