Abstract
A method and manufacturing blank for the production of high performance substantially symmetrical open volumed packing bodies is disclosed comprising the steps of forming a blank from sheet material, the blank comprising a plurality of generally identical plates interconnected in linear series by ribbon members coupling adjacent plates and defining a median strip, shaping the plates into troughs having longitudinal axes oriented perpendicularly to the median strip, and bending the median strip to bring the longitudinal axes into close proximity with one another to form an open volumed packing body having a central core defined by the aligned bores.
