Abstract

PURPOSE:To obtain a multilayer composite sheet in which different constituents are distributed alternately and regularly in the direction of the width of the sheet by providing plural apparatuses for multilamination of specific structure side by side with each other in front of a mouthpiece for extruding a composite body formed by two kinds or more of viscous liquid laminated in multilayer. CONSTITUTION:An apparatus for multilamination is constituted in a square form by two parts 71 and 71' as one unit and has induction ports 72 and 73 in the positions on diagonal lines of a square on the inlet side thereof. These ports have an intermediate horizontal partition 74 between the upper and lower parts and are communicated with a passage to the central part of the device, being kept in the horizontal state. The part 71' has a partition 75 provided in the longitudinal direction in the central part thereof and the passages separated by the partition 75 are communicated with lead-out ports 72' and 73' arranged on diagonal lines on the outlet side. These parts 71 and 71' are joined in one body by U-u, V-v, W-w and X-x shown in the figure, respectively and this is put in a quadrangular tube having a passage in the same dimensions with the outer periphery, thus the apparatus for multilamination being formed.
