Abstract

An apparatus for bending sheet-like work pieces com­ prise a main frame, a die having a longitudinally extending groove, a stamp, a stop for determining the position of a work piece with respect to the die, clamping means for clamping a working piece and a frame. The frame supports the stop and the clamping means and is pivotably around a pivot axis sub­ stantially coinciding with the groove of the die. Further the apparatus includes a lifting arm for the work pieces pivotably connected with the main frame.
The frame is pivoted into a position extending obliquely downwardly form the pivot axis and a work piece is picked up from a storage location by the lifting arm and is laid on the obliquely pivoted frame. Thereby the work piece automatic­ ally shifts against the stop, whereafter the work piece is clamped in the position as determined by the stop and the frame is pivoted into a substantially horizontal position.
