Abstract
During the construction of the nozzle beam according to DE-A-195 01 738, the insertion slit for the nozzle strip (14) is sealed on the front side of the nozzle beam by means of a screwed cover (16,17). It is easier to exchange a nozzle strip (14) if a special closing unit (26) having an opening (3) for the nozzle strip is provided on the front side, and said opening (30) is closed in a liquid-tight manner by a simply fixed insertion mandrel (31).
