Abstract
A method and apparatus are described for forming a plurality of axially extending externally concave complete flutes defining a fluted profile in a cylindrical can body 1. The apparatus comprises a correspondingly profiled mandrel 11 of maximum diameter less than the minimum diameter of the cylindrical can body and comprising a whole number of complete flutes which is less than the number of flutes on the finished can body, an elongate rail 14, means 12 for locating a cylindrical can body over the mandrel, and means 10 for rolling the mandrel relative to the rail to deform a portion of the cylindrical can body between the mandrel and the rail into the fluted profile.
