METHOD OF MAKING PLATE STRIPS OF ALKALINE CURRENT SOURCES Russian patent published in 2002 - IPC

FIELD: electrical engineering; mass production of plates for alkaline storage batteries. SUBSTANCE: according to proposed method powder active material is pressed to form continuous band by rolling using two all-drive rolls of stand. Preset density of active material is provided by applying required processing force to pressure roll. Simultaneously box and cover of strip is made of perforated ribbon, material band is placed into box, and cover is put in placed and edges of perforated ribbons are connected into lock to form strip after which required length of strip is cut by rotating knives. Ecology at production of strips is improved by placing active material in form of band into box. EFFECT: improved density and uniformity of active material enclosed in box owing to preliminarily press-forming material into continuous band with preset cross section dimensions, improved ecology. 7 cl, 9 dwg
