Abstract
Metal strips are provided which can be bent into the shape of cylindrical packing elements of the Lessing or Pall ring type. These strips have one end bent back at an acute angle to the rest of the strip and have slots cut into the strip in the vicinity of the bend. At the opposed end tabs are provided that engage with the slots when the strip is formed into a cylinder so as to hold the ends together. Such packing elements have a much greater resistance to crushing than conventional elements and can be made of much thinner metal.
