Abstract
Viscous active ingredients are introduced into the case of a galvanic cell by extrusion from a nozzle fed with the ingredients by a pumping device. The pumping device includes an elastic, substantially straight piece of hose, and a pressure roll which can be moved along the hose between two established limits, both in the general direction of the outlet nozzle to compress the hose, and in the opposite direction to assume a retracted position along the hose. The piece of hose is compressed at a point immediately adjacent to the hose segment defined between the established limits of the pressure roll so that the material to be metered does not come into contact with parts in relative motion to each other.
