1. A press for bending a blank, said press comprising a base, a longitudinally extending counterblade connected with said base and defining a support plane for the blank, at least one longitudinally extending bending blade having an edge portion with a longitudinal axis extending parallel to a longitudinal axis of said counterblade, carrier means connected with said base for supporting said bending blade, said carrier means being movable with respect to said base in a first direction perpendicular to said support plane and said bending blade being movable with respect to said carrier means in a second direction parallel to said support plane, there being provided thrust means for holding said bending blade in a first position with respect to said carrier means, first drive means operable for initially moving said carrier means in a said first direction toward said counterblade to cause said bending blade to effect prebending of the blank, second drive means operable independently from the first ones for subsequently moving said bending blade in said second direction from said first position to a second position toward said counterblade to cause said bending blade to complete bending of the blank, and adjustable stop means for setting said first and second positions of the bending blade.
