The invention relates to a method for automatically regulating the size of a nozzle discharge slot of a nozzle assembly, wherein the nozzle assembly comprises a first and a second nozzle lip and a nozzle discharge slot arranged between the nozzle lips for setting in a controlled manner a thickness profile of a conveyable melt. A plurality of adjusting elements, in particular a plurality of adjusting pins, coupled to respective thermoelements, is arranged on the first nozzle lip, the thermoelements being controllable by the controller in such a way that the slot can be adjusted by the action ofa mechanical force applied to the first nozzle lip by the corresponding adjusting element, as a result of the expansion or contraction of the thermoelements. At least two adjusting elements are simultaneously adjusted. The invention further relates to a control and/or regulation system. 本发明涉及一种用于自动化调整喷嘴机构的喷嘴出口缝隙的尺寸的方法，其中，该喷嘴机构具有第一喷嘴唇和第二喷嘴唇以及设于所述喷嘴唇之间的且用于可控调节可输送熔体的厚度轮廓的喷嘴出口缝隙。在第一喷嘴唇处设有与所属的热电偶相连的多个调节件且尤其是多个调节销，其中，该热电偶能由该调整
