<p>PURPOSE:To easily change the ratio of thickness in the respective layers of a multilayer film under operation by incorporating a regulation bar to the tip part of a flow path which is formed of both the flow path face of the surface layer side of an insert and the flow path face of a composite adapter opposed thereto and regulating this bar from the outside and changing the gap of the flow path. CONSTITUTION:The combined paths 107B'', 107C'' are constituted of both the wall face 105' of an insertion hole of a composite adapter 105 and the wall faces 107B', 107C' of the flow path of an insert 107. The regulation bars 111A, 111B are formed which are capable of replacing one part of the wall face of the flow path of the composite adapter 105 opposed to the wall faces 107B', 107C' of the combined paths 107B'', 107C'' and also capable of regulating the gap of the combined paths 107B'', 107C''. Further the regulation bars 111A, 111B are provided so that the adapter 5 can be freely rotated under operation from the outside. A spanner hanger 14 is provided to the part becoming the outer part from a flange 108. A scale reference line 15 is provided and the rate of regulation for the bars 111A, 111B can be recognized. Therefore the ratio of thickness of a film can be easily changed under operation and this change is quickly performed.</p> |
