A method and apparatus for a can with a bent end, said can and the can body.

摘要

A method for manufacturing a can, such as a paint can or a food can, comprising lospasos of: i. providing a cylindrical body (2, 21, 36, 51, 63); ii. have plunger means (14, 25, 44) in a first opening (20, 60) of the barrel (2, 21, 36, 51, 63) to define the diameter of the opening (20, 60); iii. performing a lip at the free end (6) of the first opening (20) radially outward and axially lolargo the cylindrical body (2) thereby forming a rim (47, 49, 70, 79), while the diameter of laabertura it is determined by the plunger means (14, 25, 44) applied to the opening (20, 60), characterized in that the free end (6) of the first opening (20, 60) is provided with a precurl the edge (7) before laformación flange in step iii, the step of forming the flange iii comprises forming a free end (6) provided with the precurl delborde (7) with an elongated flange (47), a step (48) is formed in the elongated rim (47) and the cylindrical body (2, 21, 36, 51) is stretched radially partially to the first free end (6, 66), demanera the elongated curl and step (49, 79) is formed in a narrow portion (43) of cilíndricoestirado body (2, 21, 36, 51, 63), and elongated and stepped rim (49, 79) rest within the imaginariaexterior sheath of the cylindrical body radially stretched (51).
