Abstract (en)
[origin: EP2604357A1] The method involves sending two press mold halves (31,32) having a semi-annular projection along a first stroke axis of the peripheral wall, for shaping groove in first pressing step, so as to form a preform of the groove. Two press mold halves (41,42) having a semi-annular projection on the peripheral wall are sent along a second lifting axis in second press step relative to peripheral wall rotated around angle of rotation to the first lifting axis.
