Abstract

A method for joining a first electrode web to a second electrode web comprises providing a first free end (11) of a first electrode web (f1); providing a second free end (l2) of a second electrode web (f2) at the first free end (11) of the first electrode web (f1); unwinding a first adhesive tape (n1) from a first feeding coil (b1) along a first unwinding path (63), the first adhesive tape (n1) comprising an unwound first piece of adhesive tape (b1a) that is positioned between a first part (n1a) of the first adhesive tape (n1) upstream and a second part (n1b) of the first adhesive tape (n1) downstream along the first unwinding path (63); cutting away from the first piece of adhesive tape (b1a) an inner portion of the first adhesive tape (n1) separating the inner portion of the first adhesive tape (n1) from a residual edge portion (69a) of the first adhesive tape (n1) extending along the first unwinding path (63) so as to keep the first part (n1a) of the first adhesive tape (n1) in connection with the second part (n1b) of the first adhesive tape (n1), the inner portion of the first adhesive tape (n1) forming a first adhesive patch (69b); applying said first adhesive patch (69b) at both said first free end (11) and second free end (l2); winding the residual portion (69a) of the first adhesive tape (n1) on a first winder (69) positioned downstream of the first feeding coil (b1) with respect to the first unwinding path (63).
