  • corresponding channels may be arranged on the outside of the rear wall 6.17 and / or on the narrower side walls of the trunk extension piece 6.1.
  • the channels 6.23, 6.24 open above the bottom 6.25 of the connection section 6.11.
  • the upper end portions 6.231, 6.241 of the channels 6.23, 6.24 are on the outside of the front wall arranged the connecting portion 6.11, which faces in the operation of the running out of the molten bath vessel 4 section of the band 1.
  • the upper end sections 6.231, 6.241 of the channels 6.23, 6.24 go into channel sections, which are arranged on the underside of the bottom 6.25 (see. Fig. 14 ).
  • the upper outlet openings of the channels 6.23, 6.24 are thus above the bottom 6.25 in a throat area, which is defined by the bottom 6.25 and the front wall of the connection section 6.11.
  • the embodiment of the invention is not limited to the embodiments shown in the drawing. Rather, several variants are conceivable, which make use of the invention specified in the appended claims even with different design. For example, it is also within the scope of the invention if the inner width of the dipped trunk extension piece 6.1 tapers towards its outlet opening 6.15, at least over a partial length, stepwise in the form of one or more inside jumps and / or in the form of differently angled trunk wall sections.
