Arrangements for tracing grooves to the sides of bricks at any angle relative to the extrusion direction used for producing bricks by ceramic products industries. The invention adds an arrangement of sheaves to the clay extruder in each of the sides of the clay which will be in the sequel used as a brick, once cut, dried and baked. Finally, the presence of such grooves in the above sides of the bricks in combination with the parallel grooves traced by a conventional extruder will contribute to the improved retention of the plaster onto the bricks in all directions and will thus contribute to the improvement of buildings and the reduction of the cost of plaster maintenance. |
