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.
