Definitions

  • This invention relates to a can body making machine and, more particularly, it relates to a portion of the side seam forming assembly of a can body maker wherein fiat can body blanks are first secured to a foaming horn or mandrel and then wrapped about the mandrel to be formed into tubular configurations.
  • fiat can body blanks are delivered to a side seam forming assembly wherein the flat blanks are converted into the tubular can bodies.
  • the can body blanks have hooks formed along their opposite edges which may be interlocked and hammered to form the side seams.
  • the tubular can body is formed by delivering a flat can body to the mandrel, securely clamping it in place and then wrapping it about the mandrel to interlock the hook edges.
