A blank for forming a spherical filling body for material-exchange columns is formed by stamping from a strip sheet of metal series of tongue-like elements extending from a middle strip. The spherical body can be formed by bending the tongue-like elements into a curved form, then bending the middle strip to form a ring. The tongue-like elements provide a plurality of drip edges to facilitate the interaction of the liquid and the gas in the material exchange column. Additional elements can be formed with the tongue-like elements to provide additional drip edges when the filling body is assembled.

A plate-shaped blank for the manufacture of a spherical filling body for material exchange columns comprising: a middle strip; and a plurality of tongue-like elements extending from the sides of the middle strip, each curved in substantially the same direction and each taper from the end adjoining the middle strip to the free end, the width of the tongue-like element at the middle strip greater than the distance between two adjacent tongue-like elements, said tongue-like elements additionally include stamped-out sections along the length thereof to define a surface section, said surface section bent in a direction opposite the curve of the tongue-like elements, and flap-like elements extending from the ends of the tongue-like elements, the flap-like elements shorter than the tongue-like elements from which they extend.
