Apparatus for performing the method includes two punches, each punch has several triangle prisms. Punches are mounted with possibility of motion one opposite to another in such a way that prims of one punch may move between prisms of another punch. Forming surfaces of punches are arranged on mutually opposite working ends of prisms. Using of the same center for starting cutting in and for forming petals allows to make high-quality petals. Realization of cutting process only between cutting edges enhanced quality of lateral sides of petals. Fixation of parts in mean position provides uniform bending aside of petals and their subsequent pressing to surfaces of parts between annular beads.
