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.

An apparatus for introducing viscous active ingredients into a case of a galvanic cell, by extrusion, comprising:
- a nozzle for feeding the ingredients;
- and
- means for pumping the ingredients to the nozzle including an elastic, substantially straight section of hose, a first pressure roll movable along the hose between first and second limits, in the general direction of the nozzle, and for compressing the hose, and in an opposite direction for assuming a retracted position, means for moving the first pressure roll only in directions perpendicular to the hose and parallel to the hose, and means for compressing the section of hose at a point immediately adjacent to the segment defined between the first and second limits.
A method for introducing viscous active ingredients into a case of a galvanic cell, comprising the steps of:
- delivering the ingredients to an elastic, substantially straight section of hose;
- and
- pumping the ingredients from the section of hose to a nozzle for delivering the ingredients to the case of the galvanic cell by selectively operating a first pressure roll movable only in directions perpendicular to the hose and parallel to the hose, and along the section of hose between first and second limits, in the general direction of the nozzle, and for compressing the hose, and in an opposite direction for assuming a retracted position, and by selectively compressing the section of hose at a point immediately adjacent to the segment defined between the first and second limits.
