ABSTRACT:
Open-ended cylindrical shells, such as might become beverage cans or containers, are necked (and/or may be flanged) at the open end by tooling including a cooperating internal mandrel and external forming roller; at the opposite end of the shell there is a chuck to clamp and spin the shell. The chuck spins the shell while the forming roller forces the rim portion at the open end of the shell progressively into contact with the opposed mandrel to form the neck and/or the flange. The tooling is repeated in sets at regular spaced intervals between and about a pair of rotating wheels, there being a shell supported between the tools at each tool position so that continuous production is achieved within a production loop or orbit which occupies limited space. Variations in shell thickness or metallurgy can be complied with by employing a variable speed drive both for the chuck and a rotatable collar which fits the open end of the shell. Gears are part of the variable speed drive. These gears are employed in the variable speed drive and by arranging the gears to be driven counter to the wheels, a gear ratio results by which the shells may be rotated rapidly so the forming operation may be performed quickly.
