Abstract

The method involves arranging slits (6, 7) in a bottom wall (3) between circumferences of outer and inner sleeve parts (2, 4) of a cup-shaped sleeve assembly (1), where the slits are produced by a punching process. A portion of the slit (6) is punched-out in a punching step, where the slits run along a circumferential direction. The portion of the slit (6) is adjacent to the circumference of the outer sleeve part. A portion of the slit (7) is punched-out in another punching step, where the portion of the slit (7) is adjacent to the circumference of the inner sleeve part.
