Definitions

the nozzles assigned to each side 31, 31 ', 32, 32' of the Bloom 27 form an angle ⁇ 1 with the longitudinal direction (direction of the axis 36) or the conveying direction 3 of the Bloom, which is different from the angle ⁇ 2 that the include nozzles associated with the adjacent side of the bloom with the longitudinal direction is different.
This measure hinder the edges 37 of Different sides of the rays hitting the Bloom do not meet each other, so that the areas of the edges 37 are descaled perfectly.
