ABSTRACT:
An apparatus is provided for manufacturing a laminated sheet wherein different molten resins are alternately laminated by providing a multitude of slits arranged at intervals and permitting the different molten resins to flow out from the adjacent slits. A value of a shortest flow path length (L1) to a longest flow path length (L2) of the molten resin that flows from an inlet to an outlet of the slit, which is a ratio of (L1)/(L2), is 0.5 or more. The slits include slits having different slit lengths. A flow quantity of the molten resin at the slit is changed by changing the intervals of the slits, length of the slits or by changing the temperature of the molten resin at the slits.
