ABSTRACT:
The present invention relates to current sources and, in particular, to a method for sealing current sources, preferably of a cylindrical shape, with an alkali electrolyte and to devices for carrying same into effect.
The method can be realized by a device, comprising a rolling die, a hold-down member adapted to position the plane of the cell cover end face perpendicular to the cell axis and to press said cover towards the cell's central support, a footstep for positioning said cell support during sealing. According to the invention, said footstep is made as a cylindrical socket with a ring projection, or has a shape similar to that of the supporting part of the cell being rolled. The rolling die comprises at least one cone-shaped section and is provided with a stop adapted to limit the motion of the hold-down member into the die.
