Abstract

A method of making a cover for the positive plate for acid batteries, comprising a set of thermally formed tubes of non-woven fabric, characterised in that a tape ( 1 ) of non-woven fabric of a width corresponding to the length of future tubes is wrapped into a single, oval loop, and the extreme ends are laid so as to form an overlap ( 2 ) in the zone between vertices ( 4 ) of the loop, then the loop is stitched crosswise to form a set of multiple channels ( 3 ) which are then thermally formed into cover tubes ( 6 ).
