A method of forming metallic current conducting lugs on an accumulator electrode plate wherein at least the region where the current conducting lug has to be formed comprises a plastic net structure which is preferably provided with a metallization which conducts electricity well, in particular of copper, which is in turn provided with a tin or lead/tin coating and/or a lead coating or a lead alloy coating. Metal strips of an alloy which melts at low temperature are applied to the two oppositely disposed surfaces of the plastic net structure in the region of the current conducting lug which is to be formed. The strips cover over at least the upper region of the current conducting lug which is to be formed. The two metal strips are pressed together from the flat sides with a high pressure while clamping the plastic net structure, preferably while being heated to a temperature which at least softens the metal strips, and preferably melts them at the edges but does not yet allow the plastic net structure to be melted or decomposed. The metal of the metal strips flows into the plastic net structure and the two metal strips are connected together at least at the edges, but preferably also in the interior of the plastic net structure.

[ What is claimed is:] [1.] A method of forming metallic current conducting lugs on an accumulator electrode plate wherein at least the region where each current conducting lug is to be formed comprises a plastic net structure which includes a tin or lead/tin coating and/or a lead coating or a lead alloy coating, the plastic net structure having two oppositely disposed surfaces and a plurality of edges which include a pair of opposite free edges, the method comprising the steps of:applying two metal strips of an alloy which melts at low temperature with flat surfaces of the metal strips to the two oppositely disposed surfaces of the plastic net structure in the region of the current conducting lug which is to be formed, with the metal strips covering over at least the upper portion of the region where the current conducting lug is to be formed; andpressing the two metal strips toward one another clamping the plastic net structure with a high pressure to soften and cause the two metal strips to flow through the plastic net structure and connect with one another at least adjacent edges of the metal strips, the plastic net structure having a sufficiently high melting temperature to prevent melting and decomposition under the high pressure.
