A method and apparatus for forming a can end In a forming press (100) Including positioning a sheet: of material between an upper punch assembly (102) and a fixed base assembly (104); cutting a can end blank (W) from the sheet of material; clamping a peripheral portion of the can end blank (W); moving the upper punch assembly (102) to clamp a central portion of the can end blank (W) between an upper panel punch (114) and a Iower panel punch (118) to define a central panel section positioned below an annular Inner bead die (116c) located adjacent to the Iower panel punch (118) on the fixed base assembly (104); and extending the upper punch assembly (102) to form an Initial annular countersink radius (VI) next to the peripheral portion of the can end blank (W)} with a substantially undeformed intermediate area extending between the Initial annular countersink radius (VI) and the annular Inner bead die (116c). An alternative embodiment of the method described above and an apparatus for carrying out this method are also described.
A method and apparatus for forming a can end in a forming press including positioning a sheet of material between an upper punch assembly and a fixed base assembly; cutting a can end blank from the sheet of material; clamping a peripheral portion of the can end blank; moving the upper punch assembly to clamp a central portion of the can end blank between an upper panel punch and a lower panel punch to define a central panel section positioned below an annular inner bead die located adjacent to the lower panel punch on the fixed base assembly; and extending the upper punch assembly to form an initial annular countersink radius next to the peripheral portion of the can end blank, with a substantially undeformed intermediate area extending between the initial annular countersink radius and the annular inner bead die.

A can end blank is initially cupped and a central portion of the cup is rolled up with an annular portion of the cup being free formed with limited contact with any tooling except to prevent wrinkling, to prevent overextension of the free formed material and to define a final geometry of the free formed material as the forming press reaches a bottom of its forming stroke. The free forming is performed by controlling the motion of a pre-panel punch using a double action piston so that the pre-panel punch is selectively moved between an extended position for formation of a cup of a cupped can end blank and a retracted position for free forming material between a central portion of the cup and a clamped portion of the cupped can end blank.
A can end blank (S) is initially cupped and a central portion of the cup is rolled up with an annular portion of the cup being free formed with limited contact with any tooling except to prevent wrinkling, to prevent overextension of the free formed material and to define a final geometry of the free formed material as the forming press reaches a bottom of its forming stroke. The free forming is performed by controlling the motion of a pre-panel punch (118) using a double action piston (123) so that the pre-panel punch (118) is selectively moved between an extended position for formation of a cup of a cupped can end blank (114) and a retracted position for free forming material between a central portion of the cup (106C) and a clamped portion of the cupped can end blank (124).
A method for forming at least one rib and a step shoulder bottom of a can body in a single drawing operation from a redrawn cup or preform which has a closed end with an inwardly tapering annular periphery that includes sufficient material to enable formation of the step shoulder bottom without having the at least one rib drawn into the step shoulder bottom.

METHOD FOR MAKING CAN BODIES HAVING AXIAL RIBS AND STEP SHOULDER BOTTOMS
A method for forming at least one rib (130) and a step shoulder bottom (SS) of a can (CB) body in a single drawing operation from a redrawn cup (110) or preform which has a closed end (BP) with an inwardly tapering annular periphery that includes sufficient material to enable formation of the step shoulder bottom (SS) without having the at least one rib (130) drawn into the step shoulder bottom (SS).
