A method for forming a curl on an open end of a metal container, for adapting the metal bottle to be closed by a cap, comprising in sequence: inserting the open end of the metal container into a powered first curler roller housing, wherein the first curler roller housing houses a set of first curler rollers, to deform the open end by turning it outwardly so as to obtain a first stage curl; inserting the open end of the metal container having the first stage curl into a powered second curler roller housing, wherein the second curler roller housing houses a set of second curler rollers, to further deform the open end and first stage curl by turning them outwardly and/or curling them so as to obtain a second stage curl; inserting the open end of the metal container or bottle having the second stage curl into a powered third curler roller housing, wherein the third curler roller housing houses a set of third curler rollers, to further deform the open end and second stage curl by turning them outwardly, curling them and/or compressing the second stage curl radially and/or longitudinally downward towards a bottom of the metal container so as to obtain a third stage curl.

A can seaming apparatus including a frame, a can handling assembly, a can driving assembly and a seaming assembly. The can seaming apparatus is configured to seal a lid to a can through a double seam can seal. The can is positioned and clamped between an upper and a lower chuck. The can driving assembly spins the can and the upper and lower chucks about an axis. The seaming assembly includes two rollers which can selectively be directed to engage the can to form the necessary crimping operations.

Various embodiments of the present disclosure are directed to seaming assembly for seaming a can lid onto a can body. In one example embodiment, a seaming assembly includes a chuck; and a knockout pad that is movable relative to said chuck in an axial direction of said chuck. The knockout pad includes a fastening element, and a holding element in a spring-loaded manner relative to the fastening element such that contact with the can lid is effected and established in a spring-loaded region.

A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with a lower wall portion of a chuck wall, and the chuck wall has an upper wall portion which connects with an inner wall of the crown. The chuck wall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall.
