Abstract
A method and apparatus for filling fibrous-structure electrode plaques for rechargeable batteries with an active compound paste, with simultaneous sizing of the plaque. The fibrous-structure electrode plaque is fed by means of a conveyor device to a roll mill whose roll nip is uniformly filled with a flowable active compound paste over the nip width. As the plaque passes through the roll nip, it is filled with active compound paste from both sides, simultaneously sized for thickness, its surface is smoothed and excess paste is removed from the main surface.
