ABSTRACT:
The method of producing galvanic primary cells including introducing an overdosage of depolarizer mass into a prepressing form and compressing the mass to constant density, forming a pressed depolarizer element by pressing an overdosage of the depolarizer mass into a cell cup through a nozzle, separating the overdosage from the depolarizer element within the cell cup along a predetermined line and allowing the overdosage to remain within the nozzle, pushing the overdosage into the following cell cup as a mass plug and adding sufficient additional depolarizer mass to nozzle to provide an overdosage. The invention also includes the apparatus for carrying out the method including a prepressing form to contain an excess of depolarizer mass, a dosage nozzle in communication with the form and receiving compressed depolarizer mass therefrom, a first ram pushing depolarizer mass into the nozzle and into a cell cup, a second ram forcing the cell cup into the nozzle for dosage application, and a separating device to move the cell cup relative to the nozzle whereby a depolarizer element can be formed within the cell cup and the excess depolarizer mass remains in the nozzle for subsequent feeding into the following cell cup.
