can oppose one another when operatively aligned as an example opening 28 can have a surface 29 and opening 26 can have a surface 30 surface 29 can define a different shape than surface 30 surface 29 can be relatively planar when compared to surface 30 as an example surface 29 can be a sheer flat opening that extends from the lateral face of die a to the other lateral face surface 30 for example such as surface 30 of die b can have a contour to the interior wall of its opening such as a convex contour referring to fig3 this interior wall is shown as a cross section of fig2 this contour of the interior face of the opening of die b is shown in fig3 as contour 30 contour 30 can be an elevated portion within the center of the opening of die b extending from lateral face 32 to lateral face 34 of die b referring to fig4 in accordance with an example aspect a plurality of dies can be arranged in groups pressing arrangement 10 can include a group 44 and end group 42 group 42 can be on the periphery of group 44 and group 44 can include dies a and b with these dies having opening surfaces of different shapes group 42 can include dies having like opening surfaces such as dies a according to an embodiment upper dies a can be opposed to one another at end portions 42 for example in accordance with example implementations having end portions 42 configured in this manner may facilitate processing by alleviating at least some of the shifting of the blank as it is being formed dies a and b can.
