Abstract
Discrete locations of an electrode web or electrode segment based on a porous metallic carrier framework, which are intended to receive the take-off conductor, are briefly heated to about 450.degree. C. and then cleared of active mass with compressed air. The heating, for which a stream of hot air is particularly suitable, has the effect of destroying the organic binder present in the active material. Following such treatment, a clean metal surface is made available for the welded attachment of the take-off conductor, of a size which is limited to the precise dimensions necessary for the connection.
