Definitions

the partial closure cam 58 and the partial closure cam follower 62 cooperate to bring the partial dies 40, 42 from their open configuration position to their overall configuration position.
the partial closing cam 58 and the partial closing cam follower 62 cooperate in the same way in order to bring the partial dies 40, 42 from their overall configuration position towards their open configuration position.
the partial dies 40, 42 are adapted to deform the side walls 12, 14 of the blank 8 separated from the punch 32 against an elastic return force against the punch, and this when the partial dies move between their position of open configuration and overall configuration position. More precisely, at least the parts of the side walls 12, 14 of the blank 8, adjacent to the free edges 18 are elastically deformed and brought into contact with the punch surface 34.
