定の厚みまでプレスするのが一般的であった。2. Description of the Related Art Conventionally, as a method of manufacturing a paste type anode plate for a sealed alkaline storage battery, Japanese Patent Publication No. 52-18379 has been used.
There is a method disclosed in the publication. As shown in FIG. 2A, the paste-like active material 2 is provided between the pair of rolls 1.
And by continuously supplying the substrate 3, one surface of the substrate 3 is filled with the paste-like active material 2 to form a sheet-like electrode plate. As shown in FIG. ′ And a sheet-shaped electrode plate are continuously supplied between a pair of rolls 1 ′, the paste 2 ′ is formed into a sheet on the other surface of the substrate 3, and at the same time, the paste 2 ′ is applied to the substrate 3 and the paste-shaped active material 2, 2 is formed on both surfaces. The electrode plate 4 filled with 'was manufactured. Also,
In order to improve the capacity density, the electrode plate 4 is generally dried and then pressed to a predetermined thickness.

為に、基体3への圧力が高くなり、基体3の変形による
不良が発生し極板を完成することは出来ない。However, in the above-mentioned conventional manufacturing method, when the paste-like active material 2 containing fibers such as carbon fibers is filled in the substrate 3 at a predetermined density, the paste-like active material 2 is obtained. Since the viscosity of the paste is low and the fluidity of the paste-like active material 2 in the traveling direction of the substrate 3 by the roll 1 is low, the pressure on the substrate 3 becomes high and defects due to the deformation of the substrate 3 occur to complete the electrode plate. I can't do that.

の充填密度が向上しないという問題があった。Therefore, a method may be considered in which the viscosity is lowered by increasing the mixed liquid of the paste-like active material 2 and then the mixture is filled, but since the fluidity is high, the density becomes low at the time of filling. If the filling amount is kept constant, the electrode plate after filling becomes thicker, so that the compression rate becomes higher when forming by the press after drying, and the base 3
Defects occur due to peeling of the active material from the. Therefore, there is a problem that the filling density cannot be improved after the electrode plate is completed because the filling amount cannot be set to a certain amount or more.

It is characterized in that after the substance is intermittently transferred to the substrate, it is uniformly formed into a predetermined thickness by a one-stage or two-stage or more roll press.

Therefore, it is possible to obtain an electrode plate having a high density and a large capacity, without being restricted by other paste-like active material, easily extending backward in the traveling direction of the substrate, without deforming the substrate.
