Harvid nedtryckes stave. 27, yarvid rorelsen overfores via vinkelarmen 20 och lankarmen 25 till stangen 24, vars anslag 29 harigenom Ores in mot vandningsstavens hake 30. Cylinderkolven bringas nu att rora sig nedat, havarmen 13 fOres tillbaka och vandningsstaven med haken 20 for darvid stangen 24 uppat, sa att avlastningsskenan 10 med amnet vrider sig omkring axeln 11 och arias-tar amnet. When a blank is advanced on the roller conveyor for treatment, the cylinder piston is in the bottom position and the sea arm 13 in the rearward position, so that the clamping jaw 12 is slightly below the top plane of the roller conveyor. After the blank has been pulled out, the arm 13 pushes the blank against the stop 9 and holds it in firm grip against it, whereupon the surface treatment can begin on one side of the blank. When this treatment is completed, the arm 13 is brought back, and the irrigation rods 16 are used for their upward movement. Then the blank is clamped again, and the treatment of the next side can be started. After all the sides have been treated, the relief anode is put into operation. Then press down sticks. 27, in which case the movement is transmitted via the angle arm 20 and the long arm 25 to the rod 24, the abutment 29 of which is thereby directed towards the hook 30 of the irrigation rod. that the relief rail 10 with the blank rotates about the shaft 11 and arias the beam.
