Abstract

1304401 Making containers VARTA GmbH 19 Jan 1970 [12 April 1969] 2531/70 Heading B5D [Also in Division H1] Cap-shaped tubes for use as separators in a primary galvanic cell comprises at least one strip of material, preferably paper, wound and glued in the form of a sleeve which is closed at one end by a bottom disc or cup, which may be of cardboard, paper or synthetic resin. Advantageously the sleeve is produced from at least 2 helically wound paper webs and a dry electrolyte is provided on and/or between the webs. In a particular example a dry strip of paper 11 forming the basic web and a paper strip 12 coated with an electrolyte adhesive a paste by application roll 17, are wound helically on a winding mandrel 14 to produce a continuous tubular sleeve which is firmly pressed by a rotating winding belt 16. The sleeve is pushed continuously to a cutting mandrel 112 rotating in the same direction and at the same speed as the winding mandrel. The cutting mandrel is reciprocated along its longitudinal axis in synchronism with a knife support 113 for the cutting blades 114. The tubular sleeve is cut into individual sleeves when the cutting mandrel is in the extended position.
