Abstract: A method of assembling a cylindrical storage battery includes the step of mounting a block of electrodes in the body of the cylindrical storage battery, and the lid thereof with a gasket is installed on the body of the cylindrical storage battery. Thereupon, the edge of the body of the cylindrical storage battery is rolled-in through the gasket to the storage battery lid, the cylindrical storage battery is filled with a measured quantity of electrolyte, the cylindrical storage battery is electrically charged and discharged and a valve is installed in the lid of the cylindrical storage battery.

Abstract: An apparatus for sealing a cylindrical storage cell comprises a main holder accommodating the storage cell, an auxiliary holder accommodating a rod, and a means for rolling-in the housing of the cylindrical storage cell including two shafts secured coaxially in the wall of the auxiliary holder. Mechanically linked with each such shaft are a seaming roller and an element for adjusting the distance between the seaming rollers interconnected therebetween, a stop means for limiting the movement of the seaming roller being in turn connected to the element for adjusting the distance between the rollers.
