ABSTRACT:
This invention relates to an arrangement at lower tools for edging presses and the like where a pair of jaws or pads are displaceable in at least the one direction by means of a system including obliquely arranged surfaces. The novelty lies in that there are arranged at a first sliding face of a sliding plate, a number of slots or recess (3) in pairs and positioned in opposing directions on each side of a central plane of the tool and at second inverted sliding faces each connected to a jaw or pad means (12) mirror inverted slots (8) having greater length than the former slots and in that in the shorter slots there are arranged keys having a depth adapted to the slots so that a protruding portion of each key projects into each of the elongated slots.
