RIBBED BREAKING MEMBRANE WITH MULTIPLE OF SALIENTS

摘要

FIELD: production of filters. SUBSTANCE: ribbed breaking membrane with multiple salients has opposite first and second surfaces, round central part and smooth ring-type flange embracing the central part. Curved line of weakness is made in membrane, surrounding central part, except of area of circumference of central part, that determines loop, around which central part is rotating during breakage. Central part is divided by diametric bulge for two located side by side halves, in limits of which membrane is bending to form multiple separate salient-concave bendings in body. EFFECT: improved design.
