Abstract

PURPOSE:To efficiently prepare a composite sheet having a cross section of plural layers arranged regularly by providing a flow-route diverting 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 diverting apparatus 61 is a unit composed of a set of components 62 and 62', the former being positioned on the upstream side and the latter on the downstream. At the inlet of the component 62, a partition 63 is provided in the upper and lower end side parts thereof, thereby the flow of a multilayer composite body being divided for both end side parts thereof into a main flow part M and two branched effluent parts S and S'. At the outlet of the component 62, the branched effluents S and S' are compressed and parted in the right and left directions respectively. On the other hand, on the outlet side of the component 62', a partition 63' is provided is such a manner that it cuts the partition 63 of the component 62 at right angles, and the effluents S and S' expand in the direction orthogonal to that in which they are partitioned at the inlet of the component 62 respectively, while the main flow M also expands in the same direction with them.
