<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for easily producing a laminated sheet in which each layer has a targeted or set thickness. <P>SOLUTION: In the apparatus for producing the laminated sheet, numbers of slits are arranged at intervals, and different molten materials are laminated alternately by discharging them from adjacent slits. The intervals and lengths of the slits positioned at both ends of a plurality of the slits are set so that in at least one slit of the slits positioned at both ends of a plurality of the slits, when an actual slit interval is Ds, an actual slit length is Ls, a virtual slit interval is Dc, and a virtual slit length is Lc, the relationship: 10≤(Ds<SP>3</SP>/Ls)/(Dc<SP>3</SP>/Lc)≤150 is satisfied. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
