Definitions

  • a two-piece can sometimes referred to as a "seamless" can, wherein the body and the base are integrally formed by drawing and wall-ironing from a blank of metal, to form a one-piece cup-shaped container, which is trimmed at the rim and finally capped after filling. It is usual for such a cup-shaped container to be made in three operations. A shallow cup-shaped blank is formed in a first operation from a flat blank. This shaped blank is then subjected to drawing and wall-ironing and the third operation is cutting off the rim margin with a knife to form a cup - shaped container of standard length.
  • Such cans have the advantages that leakage and consequent food contamination are less likely to occur, since seams are considerably reduced as compared with the traditional can.
  • the two-piece cans are more aesthetically pleasing to the eye and are easier to stack end to end.
  • the apparatus preferably includes trimming means provided near the groove co-operable with the wall ironing die for trimming the rim of the extended cylindrical wall.
  • the trimming means advantageously, has a trimming edge radially aligned with an edge of the groove, so that the bead immediately adjoins the free end of the trimmed cylindrical wall.
  • the mandrel 50 is advanced together with the sleeve 54 towards and into engagement with a blank 13 held in the cradle 42.
  • the sleeve and the mandrel enter _ the open end of the blank and the sleeve deforms the cylindrical wall 15 of the blank and urges it against the rebated wall of the drawing die 21.
  • the mandrel 50 continues to move relative to the sleeve 54 and pushes the blank through the drawing die, so that the blank is reshaped to the mandrel with a base of reduced diameter a cylindrical wall of increased length. This process is illustrated in Figure lb.
  • the mandrel 50 continues to advance and forces the re-shaped blank 13 through the first wall-ironing die 22. This process thins and lengthens the cylindrical wall of the blank along the mandrel, as is apparent from Figure lc.
  • the mandrel continues to force the blank through the second wall-ironing die 23, as shown in Figure ld, and this further thins and lengthens the cylindrical wall to its final length.
  • the invention may be applied to cans of materials other than tin coated steel, such as aluminium or aluminium alloy.
