Abstract
An improved packing body is formed by forming a first end wall of a perforated strip into an interior convolution surrounded by a peripheral convolution containing the second end wall of the strip. The convolutions may be in spiral form or concentric polygons such as cylinders joined by connector segments. Baffle elements can project from the surface of the strip at an angle to the longitudinal axis of the packing body. Tapered strips with the large end wall disposed to the interior can be bent into a shape approaching spherical.
