ABSTRACT:
A gripper unit for clamping and aligning a layer of concrete paving bricks with compound elements for forming a stretcher bond of the bricks into the form of a setting unit by means of clamping bars which can each engage at their longitudinal edges a row of bricks. The clamping bars are simultaneously longitudinally and laterally displaceable on a frame-like support element, and are mounted on the associated support element by means of a guide cross bushing. Adjacent clamping bars have at least one common hinged lever which acts as a parallelogram control and which is coupled with an actuating device for effecting pivotable movement thereof.
