  • Patent number: 4264232
    Abstract: A method and device for collecting a layer of concrete paving bricks forming a brick disk in the form of a stretcher bond which may be used as one setting unit, is characterized in that the layer of the paving bricks is clamped together laterally with a collecting clamp with respect to their longitudinal axes for aligning purposes and, after releasing the collecting clamps, each row of bricks is individually clamped to their respective position at their head ends with clamps. The clamps with the clamped rows of bricks are then displaced with respect to each other in a parallel direction to achieve the desired setting arrangement and the collecting clamp is again engaged.
