Abstract

PURPOSE:To efficiently prepare a composite sheet having a cross section of plural layers arranged regularly by providing a flow-route dividing and altering apparatus of specific structure between an apparatus for multilamination of two kinds or more of viscous liquid and an extruding mouthpiece. CONSTITUTION:A flow-route dividing and altering apparatus 6 consists of distribution plates 7, 8, 9 and 10. On the inlet side of the distribution plate 7 are formed flow-routes 7' and 7'' which divide a multilayer composite body formed in an apparatus for multilamination into equal upper and lower parts and these routes are separated to the right and left as they come near to the distribution plate 8, joining finally flow-routes 8' and 8'', respectively. There the routes are positioned horizontally to each other in the lateral direction, being in parallel, and then the flow-routes 9' and 9'', being divided equally into the upper and lower parts by the distribution plate 9, are expanded and separated to the right and left and further turned to be the routes 10' and 10'', forming a row in parallel, by the distribution plate 10. Next, the composite body is extruded from a slit 5' having the same thickness and width as those of routes 10' and 10'' joined together and thus turns to be the finished multilayer composite body 1.
