The invention relates to a method and apparatus for making can (61), such as a paint can, comprising the steps of:
i. providing a cylindrical body (2,36,51,65);
ii. arranging piston means (14,25,44,74) in a first opening (20,60,75) of the cylindrical body for defining the diameter of the opening;
iii. curling a free end (8,66) of the first opening (20,60,75) radially outwardly and axially along the cylindrical body (2,36,51,65) thereby forming a curl (47,48,57,68,70,79), such that the defined diameter of the first opening (20,60,75) is substantially circumferentially, dimensionally stable,
and to the can (61) and can body (63) made. |
