BORING HOLES IN FOIL AND CELLULAR ELEMENTS MADE THEREOF TO PROCESS WASTE GASES (VERSIONS) Russian patent published in 2012 - IPC B21D53/02 F01N1/08

Abstract RU 2440206 C2

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, particularly, to producing corrugated foil with holes. At least one flute is made in even foil whereat at least one hole is made. Note here that, at a time, foil is fed. Using thus made foil, waste gas processing devices are fabricated to process waste gases in nonstationary internal combustion engines.

EFFECT: higher quality and efficiency.
