IMPROVED PACKING

摘要

An improved packing body is formed by forming a first end wall (52) of a perforated strip (40) into an interior convolution surrounded by a peripheral convolution containing the second end wall (58) of the strip. The convolutions may be in spiral form or concentric polygon such as cylinders joined by connector segments. Baffle elements (42) can project from the surface (50) of the strip (40) at an angle to the longitudinal axis of the packing body. Baffle elements (42) can be formed by expanding a strip with slits to form apertures and raised, angled panels projecting from the top and bottom surfaces of the strip. Tapered strips with the large end wall (52) disposed to the interior can be bent into a shape approaching spherical.
