As the demand for alkaline rechargeable batteries such as nickel-hydrogen rechargeable batteries mounted as a power source in electronic devices is increasing, there is a strong demand for improved productivity, higher capacity, and lower cost.

It is manufactured by laminating an electrode member forming a positive electrode and an electrode member forming a negative electrode via a separator. These electrode members are prepared by filling a slurry-like substance obtained by kneading, for example, nickel powder or hydrogen-absorbing metal powder as an active material thereof with a binder or water, for example, into a sponge-like or non-woven fabric-like porous substrate. It is manufactured by drying and rolling.

応じて決定される。A rolling apparatus used for manufacturing such an electrode member generally transports the electrode member between a pair of upper and lower pressure rollers to which a predetermined rolling load is applied, and places the electrode member between these pressure rollers. Rolling is performed continuously by sandwiching the electrode member. The load applied between the pressure rollers is determined according to the thickness of the electrode member before rolling and the thickness to be obtained after rolling.

ある。However, in the conventional rolling apparatus, the load between the pressure rollers set at the start of rolling cannot be automatically changed in the middle, so that the thickness of the long electrode member is reduced in the middle. If it changes, for example, if the thickness increases, the rolling between the pressure rollers may not be sufficient, and the thickness of the electrode member after rolling may exceed an allowable range.

招きやすいという問題がある。On the other hand, if the thickness is reduced on the way, the electrode member is excessively compressed in the rolling step, so that the thickness of the electrode member after rolling may fall below an allowable range. Such an electrode member having a thickness after rolling out of the allowable range of the reference value cannot be used in the subsequent assembling process of the secondary battery, and is discarded as a defective product. That is, the conventional rolling apparatus has a problem that the production yield of the electrode member is likely to be reduced.

A signal is output from the control unit 14 to the control unit 14 so as to reduce the load, whereby the control unit 14 reduces the load of the load applying means 9. If the determination result in step 22 is NO, that is, since the thickness of the electrode member 1 is the reference value, the load is not increased or decreased and the process returns to step 20 and the determination is performed again. Hereinafter, this cycle is repeated.
