Abstract:
A packing element in the form of a sheet located in a first plane and having the form of a polygon with 3 to 6 corners from which a first group of spaced peripheral strips between each of the corners of the sheet are deformed in a first direction to form arched structures with the apices of at least some of the arches in a second plane parallel to the first plane and removed therefrom in the first direction, and second group of parallel strips equal in number and parallel to the corresponding strips in the first group but each being displaced radially inwardly from the corresponding strip from the first group, each strip being deformed out of the first plane in a second direction diametrically opposite to the first direction to form arches with apices at least some of which are in a third plane parallel to the first plane, and an axially central aperture formed in the sheet and defined by a generally circular periphery.
