Abstract
Packing elements of the Pall ring type having improved resistance to crushing even though made from thinner gauge metal can be obtained by providing attachment means that hold overlapping ends of the ring together and resist deformation.
Claims6
A packing element formed by bending a metal strip into a generally cylindrical shape with overlapping ends, said ends being provided with attachment means which releasably engage to hold the ends together when overlapped, wherein the attachment means comprises at least one pair of flaps projecting from the plane of the strip at essentially the same angle and in the same direction, with each flap located adjacent an end of the strip in the region of overlap when the element is formed, and at least one cooperating slot adjacent one of the flaps such that the flap formed on the opposed end engages with the slot when the element is formed.
