Process for fastening conductive bars

A process for fastening conductive bars in slots of bundles of laminations provided with core ducts, comprising:

• applying an electro-conductive polymer comprising an elastomer as a soft material which is not cross-linked into a bottom of a corresponding slot in a middle of a partial bundle of laminations
• by introducing the elastomer under pressure with a needle dosing device through a bore hole in a slot wedge at a central portion of the slot;
• and
• embedding a conductive bar into the polymer which is not cross-linked and distributing the elastomer by pressing in the conductive bar so that a predominantly enclosed elastomer layer is produced at the bottom of the slot with the elastomer layer expanding at slot flanks.

• the conductive bar including a top portion, and further comprising applying an electroconductive elastomer as a soft material which is not cross-linked onto the top of the conductive bar;
• pressing in an intermediate bar so that a predominantly enclosed elastomer layer is produced that is substantially parallel to the bottom of the slot with the elastomer layer expanding at slot flanks.
